Quantitative inheritance of some wheat plant traits
Provedor de dados: Genetics and Molecular Biology
Autores: Novoselovic,D.; Baric,Marijana; Drezner,G.; Gunjaca,J.; Lalic,A.
The objective of this study was to estimate gene effects and genetic variability for some quantitative traits of two winter wheat crosses (Soissons/Zitarka and Soissons/Sana) by generation mean analysis. In most cases a digenic epistatic model was sufficient to explain variation in generation means. The additive-dominance model was adequate for plant height and grain weight per spike of the longest culm. In two cases (grain yield per plant and single grain weight) these models failed to explain variation in generation means, implying the presence of higher order interactions or interactions between linked loci. Dominance effects and additive x additive epistasis were more important than additive effects and other epistatic components. Only complementary...

Generation mean analysis for quantitative traits in sesame (Sesamum indicum L.) crosses
Provedor de dados: Genetics and Molecular Biology
Autores: Sharmila,Vijayarajan; Ganesh,Siruthaiyur Krishnamoorthy; Gunasekaran,Mahalingam.
To study the nature and magnitude of gene effects for yield and its components in sesame (Sesamum indicum L.) we carried out generation mean analysis using the following four crosses of different sesame cultivars: VS 9510 x Co1; NIC 7907 x TMV 3; Cianno 13/10x VRI 1; and Si 1115/1 x TMV 3. The P1, P2, F1, F2, BC1 and BC2 of these generations were studied for seven quantitative traits. The analysis showed the presence of additive, dominance and epistatic gene interactions. The additive dominance model was adequate for plant height in the NIC 7907 x TMV3 and Si 1115/1x TMV 3 crosses and for capsule length in the VS 9510 x Co1, NIC 7907 x TMV 3 and Si 1115/1 x TMV 3 crosses. An epistatic digenic model was assumed for the remaining crosses. Duplicate-type...

O trabalho teve como objetivo gerar informações sobre a capacidade combinatória de linhagens de pimentão por meio da análise dialélica multivariada. Foram utilizadas 13 linhagens de pimentão previamente selecionadas com base na reação ao mosaico amarelo do pimentão, sendo oito linhagens com reação do tipo resistência e cinco com reação do tipo suscetibilidade, num dialelo 8 x 5, mais as linhagens parentais. Os 53 tratamentos foram avaliados em estufa em delineamento de blocos casualizados com quatro repetições, sendo avaliadas a produção total e precoce de frutos, massa média de frutos e altura de plantas. A partir dessas quatro características foi realizada a análise dialélica univariada e multivariada. A análise dialélica multivariada apresentou...

Identification of populations and hybrid combinations of maize for in natura consumption

ABSTRACT Brazil is one of the leading countries in the production of maize (Zea mays), with great potential for growing green maize, which has a superior commercial value in relation to maize marketed in the form of grains. Although important, the availability of cultivars recommended for the production of green maizeis still very scarce. The objectives of the present study were to estimate genetic parameters and to identify promising hybrid combinations for the development of new green maize cultivars to farmers. In the summer crop of 2016/17, ten hybrid combinations obtained through a complete diallel of five maize populations, with attributes for in natura consumption, were evaluated in two sites of the state of São Paulo, Brazil: the Instituto...
