Combining Ability, Gene Action and Heterosis in Some Inbred Lines of Maize at Two Sowing Dates Using Factorial Mating Design
Combining ability, gene action and heterosis was studied for no. of days to 50% tasseling, no. of days to 50% silking, flag leaf area, plant height, no. of rows/ear, no. of grains/row, 300-grain weight and grain yield/plant in a Factorial Mating in Randomized Completely Randomized Design conducted separately in spring and autumn sowing dates, 2013 through hybridization between three parents of ...
متن کاملGenetic Distance Based on SSR Markers and Testcross Performance of Maize Inbred Lines
The identification of parental inbred lines to develop superior hybrids is a rather costly and time-consuming step in maize breeding. In some cases, pedigree information has been used to select diverse parental lines. In the case of Iranian maize inbred lines, this information is not fully available. In this study we investigated the genetic distance (GD) based on Simple sequence Repeats (SSR) ...
متن کاملgeneral yield and specific combining ability and heterosis of some cucumber lines in partial diallel design
combining ability and heterosis were studied in a 6×6 partial diallel cross during 2007-2009 to see the nature of gene action in cucumber (cucumis sativus l.). analysis of variance revealed high significant differences among all the f1 hybrid means and among their respective six parental values for all the traits examined. the mean squares attributed to general combining ability (gca) and speci...
متن کاملgeneral and specific combining ability and heterosis estimation of some cucumber lines for qualitative traits in partial diallel design
partial diallel design can be used to investigate the general and specific combining ability, and heterosis. combining ability and heterosis were studied in a 6×6 partial diallel cross to see the nature of gene action for fruit quality indices in cucumber (cucumis sativus l.) during 2007 to 2009. analysis of variance revealed highly significant differences among all the f1 hybrid means and thei...
متن کاملIdentification of genetic factors contributing to heterosis in a hybrid from two elite maize inbred lines using molecular markers.
The use of molecular markers to identify quantitative trait loci (QTLs) affecting agriculturally important traits has become a key approach in plant genetics-both for understanding the genetic basis of these traits and to help design novel plant improvement programs. In the study reported here, we mapped QTLs (and evaluated their phenotypic effects) associated with seven major traits (including...
