Abstract: leaf rust, leaf spot or brown spot and powdery mildew, caused by puccinia recondita tritici, bipolaris sorokiniana and blumeria graminis tritici, respectively, are wheat diseases that may severely decrease crop yield. several practices are recommended for the control of these diseases such as cultivar resistance, planting at a suitable time, and chemical control, without which the crop frequently becomes uneconomical. the objective of the present work was to evaluate, under field conditions, the response of six wheat cultivars, iac 24, iac 289, iac 350, iac 362, iac 364 and iac 370, in four experiments, carried out from 2000 to 2003 at cap?o bonito, state of s?o paulo, brazil. the experiments were set out in a randomized block design with four replications, and analyzed as a 2 x 6 factorial, being fungicide treatment (with and without) the factor 1 and cultivar the factor 2. severity of the diseases was graded in a scale that ranged from 0 to 9, (0 = without symptoms and 9 > 60% of the foliar area affected by disease). grain yield and the thousand kernel weight (tkw) were also assessed in each experiment. powdery mildew was only observed in 2000, but leaf rust was detected in all years in high severity indexes (30 to 60% of leaf area affected by the disease). leaf spot, detected in the last three years, from 2001 to 2003, showed the highest severity indexes in the rainiest year, 2001 (up to 60 % of the leaf affected by the disease). in all years the fungicides were efficient to control the diseases in all experiments and resulted in higher tkw and in grain yield increases. the cultivars with the longest crop cycles, iac 370, iac 289 and iac 350, had the highest responses in yield to the chemical control, despite the fact that the last two cultivars were less affected by the diseases in the control plots, showing that not only cultivar resistance, but the crop cycle and the yield potential, characteristic of each cultivar, were important in the response to the chemic

Abstract: Seed from the sensitive wheat (Triticum aestivumL.) cultivar Anahuac was treated to gamma-ray irradiation and eleven Al3+ tolerant mutants selected. The objective was to compare these mutants to the original Anahuac and to the tolerant wheat cultivars IAC-24 and IAC-60 from 1994 to 1996 in acid (Cap o Bonito) and limed (Monte Alegre do Sul) soil field trials, in the State of S o Paulo, Brazil. Grain yield and agronomic characteristics were analyzed. All the mutant lines yielded higher than the sensitive Anahuac cultivar in the acid soils of Cap o Bonito. Under limed soil conditions, 10 mutants had a similar yield to the original sensitive cultivar and one a lower yield. The majority of the mutants were similar in yield to the tolerant cultivars IAC-24 and IAC-60 under both conditions. Some of the mutants showed altered agronomic characteristics, but these alterations did not generally influence the grain yield. The results indicated that tolerant lines with good characteristics may be obtained from a susceptible cultivar by mutation induction, thus allowing cropping under conditions where Al3 + is a limiting factor.

Abstract: seedlings of 41 different citrus species and varieties were massively colonized with the citrus brown aphid toxoptera citricidus, obtained from pêra sweet orange (citrus sinensis) trees, presenting symptoms of the "cap?o bonito" complex of the citrus tristeza virus (ctv). the objective was to evaluate resistance or tolerance of the varieties to that virus complex, but even after eight months of inoculation no stem pitting was observed in the plants. otherwise, the presence of galls similar to those induced by the vein enation-woody gall disease was observed in 73% of the plants of volkamer palermo (citrus volkameriana), 60% of the volkamer catania 2, 2% of the rangpur lime d.22.30 (citrus limonia), 13% of the volkamer australian red, the rangpur lime hybrid, the orlando tangelo (citrus reticulata x citrus paradisi) and the florida rough lemon (c. jambhiri), and 7% of the carrizo citrange (poncirus trifoliata x citrus sinensis). the highest incidence and the largest gall size were observed in the palermo volkamer showing that this clone would be the most suitable to be used as an indicator plant in biological indexing tests for the disease. there are no previous reports in the literature about the occurrence of woody galls in orlando tangelo and carrizo citrange.
