Pecosa-Baer: A New Cultivar of New Cultivar Cultivar of White Lupin with Determined Bushy Growth Habit, Sweet Grain and High Protein Content
von Baer,Erik; von Baer,Ingrid; Riegel,Ricardo;
Chilean journal of agricultural research , 2009, DOI: 10.4067/S0718-58392009000400013
Abstract: the expansion of white lupin (lupinus albus l.) cultivation in chile is subject to the availability of cultivars presenting high yield potential, tolerance to the main fungal diseases and homogeneous ripening. in response to these requirements, a new cultivar has been developed and registered as ?liapec->1?, commercially registered as ?pecosa-baer?. this new cultivar has determined bushy growth habit. its flowering period is concentrated in approximately 40 days, less than the 77 days of cv. rumbo-baer. this trait allows it to reach harvest without heterogeneity problems. the seed is speckled, flat and medium-sized (370 g/1000 grains aprox.). the kernels are sweet and have a high protein content of around 41% (dry matter basis). in field assays, ?pecosa-baer? presents a good tolerance to diseases caused by colletotrichum lupini and pleiochaeta setosa. the new cultivar has outstanding stability and yield levels, even under low fertilization conditions. an average yield of 5.43 t ha-1 was obtained over four seasons in two locations. in order to maximize its yield, ?pecosa-baer? must be sown between april and june at a rate of 140-160 kg ha-1. given the high protein content and low alkaloid levels of the seeds, they can be included in the diet of all types of animals.

Rapid emergence and a vigorous growth prevent the seed tubers from infections by soil microbes and allow a rapid interception of solar radiation. In this work, the effect of the potassium phosphites (KPhi) applied to seed tubers of two potato cultivars on crop emergence and early growth was studied. Two experiments were performed under greenhouse and field conditions. Emergence of plants, leaf area, dry matter and the number of primary stems were measured in both experiments. Furthermore, mycorrhizal colonization was also measured on roots under field conditions. The application of KPhi reduced the period between planting and emergence, and increased leaf area and dry matter. The ratio between dry matter of aerials and underground organs was not affected by KPhi. Indigenous mycorrhizal colonization increased after KPhi application to seed tubers. These results confirm the benefit of the application of KPhi to seed tubers on early plant growth and suggest that their application in crop production would be advantageous.

American Journal of Plant Sciences (AJPS) , 2019, DOI: 10.4236/ajps.2019.104037
Abstract: This investigation was conducting to explain that four barley genotypes varied in their drought tolerance according to their genotype and their tested organs. It can be recorded that growth parameters (fresh, dry matter and length, water content, leaf area and pigment contents) were decreased as decreasing M. C. in the soil. This indicated that Giza 123 was the superior in its drought tolerance and Giza 129 was the interior and both cv. Giza 2000 and cv. Giza 124 were the intermediated between them. This concomitant with increase in soluble sugar and soluble protein content of both organs in Giza 123 and shoot Ca++, this related with lower value of OP other than genotypes, in Giza 2000 this was related with a huge accumulation in soluble protein of shoot and root, shoot amino acids and root proline reach 3-folds than control plants as decreasing M. C. Whereas drought stress increased soluble protein only in Giza 124 while in Giza 129 decreasing M. C. increased soluble protein, amino acids and proline contents in shoot and root and shoot Ca++. The values of OP increased as decreasing M. C. in four barley cultivars concomitant with their drought tolerance. Also, SA application was markedly enhanced the production of growth parameters in shoot and root with varied degree according to each tested barley genotypes. SA application was significantly increased OP in shoot, root and spike of barley pants. Spraying vegetative parts with 0.5 mM SA was markedly increased the soluble sugar, soluble protein and amino acids in shoot, root and spike of four barley cultivars. On the other side, SA application lowered the accumulation of proline in shoot and root of barley genotypes. SA treatment induced no significant change in K+, Ca++, and Mg++ in shoot, root and spike of Giza 123, it significantly increased K+, Ca++, and Mg++
Rapid regeneration of stable transformants in cultures of potato by improving factors influencing Agrobacterium-mediated transformation  [PDF]
Bipasha Chakravarty, Gefu Wang-Pruski
Advances in Bioscience and Biotechnology (ABB) , 2010, DOI: 10.4236/abb.2010.15054
Abstract: An efficient and rapid Agrobacterium tumefaciens-mediated transformation protocol was developed to generate activation-tagged mutant lines with the aim of large-scale functional analysis of the potato genome. The explants were inoculated with an Agrobacterium strain harboring the binary plasmid pSKI074 containing four CaMV 35S enhancers in the T-DNA region which activates the downstream genes in the host plant after its integration. Various parameters investigated to increase transformation efficiency were the type and age of explant, cultivar, hormone combinations, preculture of explants, period of co-cultivation with bacteria and concentration of bacterial cultures used for transformation. Stem explants from 5 week old plantlets of cv. Bintje which had undergone phytohormone pretreatment for 4 days, inoculation with diluted bacterial concentration of OD600 = 0.2 containing acetosyringone followed by 2 days of co-cultivation and selection in media with IAA and trans-zeatin all helped in greatly improving the transformation efficiency. The total time required from infection to rooted shoots was 6-7 weeks. Initial evidence for stable integration and expression of the transgenes by PCR analysis showed that over 93% of the regenerated lines were transgenic and this was confirmed by Southern hybridization.

American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.515237

During 2013-2014 a field experiment was conducted at experimental area of Faculty of Agriculture under Lasbela University of Agriculture, Water and Marine Science, Uthal, Lasbela to evaluate the influence of various row spacing on the yield and yield components of Raya Anmol and Faisal Canola under coastal climatic conditions of Lasbela. Randomized complete block design (RCBD) with factorial arrangement having 3 replications was used. Experiment comprises two canola varieties, C1 = Raya Anmol, C2 = Faisal Canola at 3 row spacing distances RS1 = 30 cm, RS2 = 45 cm and RS3 = 60 cm respectively. Result showed that yield and yield contributing traits are significant. It was concluded that seed yield of C1 (Faisal Canola) was better as compared to that of Raya Anmol. Row spacing (RS3 = 60 cm) yielded more crop canopy and the highest number of pod per plant, pod length and seed yield under agro climatic condition of Lasbela as compared to other densely arranged row spacing.

Freezing temperatures cause different levels of freezing injury and change biochemical components of trees. In this study, the range of survival temperature and variation in electrolyte leakage, and in concentrations of sugar, starch, and proline were determined in peach twigs (Jinmi, Changhowonhwangdo, and Kawanakajima Hakuto) exposed to artificially controlled freezing temperature. Freezing temperatures at which the plants were damaged by stress were found to be -21°C in Jan. and Feb., -18°C in Mar., and -6°C in Apr. Electrolyte leakage increased as temperature decreased from -15°C to -24°C at each assessment time. Sugar gradually decreased after the endodormancy period in the late part of winter, and sugar concentration was overall

Advances in Bioscience and Biotechnology (ABB) , 2015, DOI: 10.4236/abb.2015.65034
Abstract: Arbuscular mycorrhizal fungi are key components of soil micro-flora and obviously interact with other microorganisms in the rhizosphere which is the zone of influence of plant roots on microbial populations and other soil constituents. Keeping in view the importance of AM fungi, the present study was undertaken for assessing the AM fungal spore population dynamics in the rhizosphere soil and its colonization in rhizosphere soils in relation to soil physico-chemical factors. Present study represents an attempt to establish the qualitative and quantitative distribution of AM fungal species in rhizosphere soils of wheat. Thirteen different wheat cultivars collected from four different sites of Lalganj Pratapgarh (U.P.), India were examined for the AM infection. All the wheat cultivars were found to be infected with arbuscular mycorrhizae. However, their population in rhizosphere and root infection varied to a considerable extent from species to species. The maximum spore population and highest percentage of root colonization were found with the rhizosphere soil of cultivars Ankur Kedar.

Abstract: Medna bijela is an autochthonous cultivar of the third Adriatic vine-growing subregion. Its synonyms in use are: Buboj, Bumba, Medna, Rizavac, Zlo der etc. No detailed ampelographic study has been made to date; based on our research this cultivar is classified in the ecological-geographical group of Convarietas Pontica, Negr. Subconvarietas Balcanica, Provarietas Mesocarpa, Nem., Subprovarietas Dalmatica Nem. It is a medium lush wine cultivar with some 16-17 % of sugar and 6.0-7.0 g/l of total acidity, with a yield of 2.5-3.5 kg of grapes per grapevine and a load of 16 buds per grapevine. The wines are light, acidulous, with a specific fine aroma of honey, which is implied in the very name of the cultivar. It is recommended that the research should be continued, particularly on clonal selection.
Rojo INIFAP, nueva variedad de frijol de grano rojo para el trópico de México Rojo INIFAP, a new red grain bean variety for the Tropic of Mexico

Revista mexicana de ciencias agrícolas , 2010,
Abstract: En los Distritos de Desarrollo Rural, Centro y Altos de la Secretaría de Agricultura, Ganadería, Desarrollo Rural, Pesca y Alimentación del estado de Chiapas, existen áreas donde se siembran materiales criollos de frijol de grano rojo, los cuales se comercializan tanto en los mercados locales de las comunidades, como en la capital del estado, donde también se comercializa grano de frijol rojo proveniente de Centroamérica. Aunque estos genotipos tienen adaptación específica, son de bajo rendimiento potencial y susceptible a enfermedades. En esta entidad existe un creciente interés por parte de los agricultores por la siembra de este tipo de grano, lo cual obedece al establecimiento cada vez mayor de inmigrantes centroamericanos en el estado, que culturalmente consumen frijol de grano rojo y por lo tanto aumenta la demanda local de este tipo de frijol. Por otra parte, al incrementar la superficie de siembra y el rendimiento de frijol de grano rojo, representa una oportunidad para el estado de Chiapas de exportar este tipo de grano, considerando la demanda que hay en El Salvador, Honduras y Nicaragua, así como en los Estados Unidos de América, donde radican habitantes de estos países centroamericanos, además de promover su consumo en el país. In the Rural Development Districts (DDR), Centro y Altos of Secretaría de Agricultura, Ganadería, Desarrollo Rural, Pesca y Alimentación (SAGARPA) in the State of Chiapas, there are areas where creole materials of red grain bean are sowed, which are traded in local markets where they are produced, as in those of State capital, where it is also traded red grain bean from Central America. Although these genotypes have specific adaptation, they are from low yield potential and susceptible to diseases. In this state there is a growing interest in the farmers for sowing of this type of grain, which stands for the increasing establishment of Central American immigrants in the state that culturally consume red grain bean and to the increase of the local demand for this grain type. On the other hand, when increasing sowed surface and red grain bean yield, it represents an opportunity to Chiapas for exporting this seed type, considering the current demand at El Salvador, Honduras and Nicaragua, as well as in United States of America, where inhabitants of these Central American countries reside, besides promoting their consumption in the country.
