general and specific combining ability of some sunflower inbred lines and restorers
in order to produce new hybrids and evaluate the general and specific combining ability of sunflower inbred lines and restorers, four inbred lines and six restorers were selected in 2004. twenty-four f1 hybrids were derived in 2004 and evaluated on a rcbd design with three replications in 2005. the results of variance analysis showed that treatments were significantly different for all traits e...
متن کاملstudy on general combining ability of inbred lines and heterosis of sunflower crosses in different moisture conditions
to study general combining ability (gca) and estimation of heterosis in sunflower inbred lines for seed yield and other three agronomic traits, 68 inbred lines crossed with open pollination variety lakumka. in next year inbred lines along with topcrosses were planted in rcbd with 2 replications under two moisture conditions in sararood agricultural research station. analysis of variance in both...
متن کاملCombining ability of tropical and temperate inbred lines of popcorn.
In Brazil, using combining ability of popcorn genotypes to achieve superior hybrids has been unsuccessful because the local genotypes are all members of the same heterotic group. To overcome this constraint, 10 lines (P(1) to P(10)) with different adaptations to tropical or temperate edaphoclimatic environments were used to obtain 45 F(1) hybrids in a complete diallel. These hybrids and three c...
متن کاملgeneral and specific combining ability for agronomic and seed quality traits in some inbred lines of sunflower
production of high yielding hybrid cultivars is among the main objectives of breeding programs in sunflower and on evaluation of the combining ability of the inbred lines necessary to select for the appropriate parental lines for production of hybrid cultivars. this study was conducted to investigate the general and specific combining ability and the mode of inheritance for agronomic and seed q...
متن کاملMonitoring Three Plasmopara halstedii Resistance Genes in Iranian Sunflower Inbred Lines
Background: Downy mildew caused by Plasmopara halstedii is one of the most devastating diseases of sunflower worldwide. So far several dominant resistance genes designated as Pl have been identified and their molecular markers linked to these genes are available. However, no information on the resistance genes is available in Iranian lines. Objective: In this study, the presence of three map-b...
