Abstract: Avaliou-se a divergência genética entre quinze linhagens (Hav 13, Hav 14, Hav 21, Hav 22, Hav 25, Hav 38, Hav 40, Hav 41, Hav 49, Hav 53, Hav 56, Hav 64, Hav 65, Hav 67 e Hav 68) e cinco cultivares (Macarr o Favorito AG480, Macarr o Preferido AG482, Manteiga Maravilha AG481, Teresópolis AG484 e Macarr o Bragan a) de feij o-vagem de crescimento indeterminado, utilizando-se vinte características agron micas. O ensaio foi conduzido na AGENCIARURAL - EE de Anápolis, no período de 30/04 a 10/08/1998. Os dados foram submetidos às análises de variancia e multivariada (distancia D2 de Mahalanobis e o método de agrupamento de Tocher). Houve diferen as significativas entre os genótipos para as características consideradas. Os genótipos Hav 13, Hav 49, Hav 56, Hav 64, Hav 68, Favorito AG480 e Teresópolis AG484 destacaram-se com rela o ao conjunto de características favoráveis a produtores e consumidores. Houve maior freqüência de pares com maiores distancias, quando um dos componentes era a cultivar Teresópolis AG484 ou Hav 49, e de pares com menores distancias quando seus componentes tiveram como ancestral comum a linhagem Hab 229. Os genótipos distribuíram-se em quatro grupos, sendo um constituído exclusivamente pela linhagem Hav 49, outro englobando as cultivares Manteiga Maravilha AG481 e Teresópolis AG484. A linhagem Hav 41 e as cultivares Macarr o Favorito AG480 e Macarr o Preferido AG482 um terceiro grupo, e os demais genótipos um único grupo. As características que mais contribuíram para a divergência entre os genótipos foram o número de dias para o início de flora o e o comprimento das vagens, com 58,11% do total, seguidas da porcentagem de palha na vagem seca, da largura das vagens, das alturas das plantas nas duas épocas avaliadas, do peso médio de vagem e do número de vagens por planta que, em conjunto, contribuíram com 85,73% do total.

Abstract: Estudaram-se a adaptabilidade e estabilidade de 15 genótipos de feij o-vagem de crescimento indeterminado em rela o a oito ambientes. Houve diferen as significativas entre genótipos em apenas três ambientes. As linhagens Hav 13, Hav 14, Hav 53 e Hav 56 igualaram-se aos genótipos mais produtivos em todos ambientes. As linhagens Hav 13, Hav 21, Hav 25, Hav 38, Hav 40, Hav 56, Hav 65 e a cultivar Favorito Ag 480 foram estáveis e as demais imprevisíveis, de acordo com a metodologia de Eberhart & Russell. Os genótipos apresentaram ampla adaptabilidade, exceto Hav 67 adaptável a ambientes desfavoráveis. A linhagem Hav 13, de vagens cilíndricas e sementes brancas, foi a alternativa mais vantajosa à cultivar Favorito Ag 480, utilizada como testemunha.

Horticultura Brasileira , 2002,
Abstract: Estudou-se a resposta de feij o-vagem de crescimento indeterminado à fertilidade do solo em Anápolis (GO). Utilizaram-se sete linhagens (Hav 13, Hav 38, Hav 40, Hav 49, Hav 56, Hav 64 e Hav 68), e as cultivares Favorito Ag 480, Macarr o Bragan a e Teresópolis Ag 484, em sete doses da formula o 4-30-16 aplicadas ao solo (D0= 0; D1=200; D(2)400; D3=600; D4=800; D5=1000 e D6=1200 kg/ha). Houve diferen as significativas entre genótipos para todas características avaliadas, dentro de cada dose do formulado, exceto para produtividade, no quinto nível, e para altura média das plantas no nível mais elevado de fertilidade. As linhagens Hav 49 e Hav 64 igualaram-se aos genótipos de maiores rendimentos em todos os ambientes. O nível médio de fertilidade foi o mais conveniente, do ponto de vista econ mico, para todas as características consideradas. Com exce o de Hav 13 e Teresópolis Ag 484, que se mostraram imprevisíveis quanto à produtividade, Hav 13 e Hav 64, quanto ao número de vagens por planta e Favorito Ag 480 quanto à altura média das plantas, os demais genótipos foram estáveis. Todos os genótipos responderam proporcionalmente à melhoria do ambiente para produtividade, número de vagens por planta e altura das plantas. Quanto ao peso médio das vagens a linhagem Hav 40 respondeu menos que proporcionalmente ao aumento da fertilidade do solo, mostrando-se adaptável a solos menos férteis, enquanto a cultivar Teresópolis Ag 484 respondeu mais que proporcionalmente à melhoria da fertilidade mostrando-se adaptável a solos mais férteis.

Abstract: the resistance to meloidogyne incognita and propagation compatibility of thirteen pepper rootstocks (nine capsicum chinense; three c. annuum and one c. frutescens) were evaluated under rubia r, margarita and maximos red pepper hybrids grafting. the experiment was carried out in 2005, in jaboticabal, s?o paulo state. plants were cleft and notch grafted and, 25 days later, the pant surviving was evaluated. later, the grafted plants and plants without stump were transplanted to a greenhouse and inoculated, individually, with 5,000 eggs and infants in the second phase of m. incognita. the rootstock resistance to nematodes was evaluated at 181 days after inoculation, based on the reproduction factor. the stump/rootstocks compatibility was evaluated considering yield and quality of fruits obtained through seven harvests, 113 to 181 days after seedling transplant. an average of 99,69% of surviving plants was obtained, 25 days after grafting date. the c. annuum and c. frutescens rootstocks were resistant to m. incognita at the end of the vegetative cycle and they provided to grafted plants the higher and lower fruit production and quality respectively, being called compatible and non compatible to stump with rubia r, margarita, and maximos red pepper hybrids. 'maximos' and 'margarita', when grafted, presented better productivity and fruit quality, than 'rubia r'; when non-grafted the productivity did not differ among them, prominence having for 'margarita' about fruit quality.
