Correlação da heterose de híbridos de milho com divergência genética entre linhagens. Repositório Alice
GUIMARÃES, P. de S.; PATERNIANI, M.E.A.G.Z.; LÜDERS, R.R.; SOUZA, A.P. de; LABORDA, P.R.; OLIVEIRA, K.M..
O objetivo deste trabalho foi avaliar a produtividade de híbridos simples de milho obtidos de cruzamentos dialélicos entre linhagens divergentes, estimar a capacidade de combinação das linhagens e confirmar se a divergência genética entre as linhagens, obtida por marcadores moleculares, é correlacionada com a heterose dos híbridos simples no campo. Trinta e seis híbridos resultantes do dialelo parcial e as 12 linhagens parentais foram avaliadas em Campinas em blocos ao acaso, com três repetições e duas testemunhas. A capacidade de combinação das linhagens foi estimada de acordo com o modelo 4 de Griffing. Estimaram-se a correlação matricial, mediante a estatística de Mantel, entre heterose, produtividade e capacidade específica de combinação com...

Genotype x environment interaction and its implication in identification of common bean populations with high calcium content. Repositório Alice
FERNANDES, S. B.; ABREU, A. F. B.; RAMALHO, M. A. P..
The common bean is a food with high mineral content. Of the various types of beans cultivated in Brazil, carioca type beans are the most consumed. The aim of this study was to identify promising common bean populations with an emphasis toward the selection of carioca type bean lines with high calcium content. We also aimed to verify whether and how the crop season and the genotype (parental line and hybrid populations) x crop season interaction affect calcium content. A group of 3 lines of good agronomic characteristics were crossed with a group of 4 lines with high calcium content in a 3 x 4 partial diallel design. Great variability was identified among both the parental lines and the hybrid populations derived from the diallel crosses among the parental...

Heterosis in crosses among white grain maize populations with high quality protein. Repositório Alice
RODRIGUES, M.C.; CHAVES, L.J.; PACHECO, C.A.P..
The objective of this work was to investigate heterosis and its components in 16 white grain maize populations presenting high quality protein. These populations were divided according to grain type in order to establish different heterosis groups. The crosses were carried out according to a partial diallel cross design among flint and dent populations. Seven agronomic traits were evaluated in three environments while four leaf diseases and incidence of corn stunt were evaluated in one. Least square procedure was applied to the normal equation X'Xb = X'Y, to estimate the model effects and their respective sum of squares. Among the heterosis components, in diallel analysis, significance for average heterosis in grain yield, number of days to female...

Selection of melon genotypes with resistance to Didymella bryoniae using a diallel approach Agronomy
Santos, Lucas da Silva; Diniz, Guilherme Matos Martins; Gomes, Rafaelle Fazzi; Silva, Edgard Henrique Costa; Silva, Alysson Jalles da; Braz, Leila Trevisan.
The development of melon lines resistant to gummy stem blight (GSB) is an important strategy for decreasing losses caused by this disease. Thus, selecting the best parents for such a goal is essential. We evaluated the general (GCA) and specific (SCA) combining abilities of lines and accessions to guide the selection of the most promising parents to develop GSB-resistant lines. Six genotypes representing two groups (group I - susceptible: group II - resistant) were crossed in a partial diallel mating design. The genotypes were evaluated for disease expression using a rating scale from 0 (resistant) to 4 (susceptible). Estimates of GCA were negative and significant for the accessions PI 420145 and PI 482398, which can be suggested for crosses aimed at...
