COMBINING ABILITY ANALYSIS IN RICE ( Oryza Sativa L . )
Twenty hybrids were produced using five CMS lines viz., BRRI3A, BRRI9A, IR73328A, BRRI10A and IR78355A and four restorers viz., BRRI12R, BRRI13R, BRRI14R and BRRI15R following line x tester mating design to find out the best combination (s) in respect of their combining ability effects among the parents and hybrids at BRRI, Gazipur, Bangladesh from July 2008 to May 2009. Data were recorded from...
متن کاملcombining ability and heterosis in rice (oryza sativa l.) cultivars
quantitative valuations of observed heterosis for 11 traits of 15 f1 hybrids generated by half diallel crosses of six diverse rice cultivars (domsefid, hashemi and binam, three iranian local cultivars; dorfak, kadous and ir30, three improved cultivars), were made in this study. fifteen f1 hybrids and their parents were evaluated in a randomized complete block design with three replications at t...

15 صفحه اولCombining ability of rice genotypes under coastal saline soils
Six lines and five testers were crossed in line x tester fashion and the F1s were evaluated under coastal saline situation. The ratio between the estimates of additive and dominance variances indicated preponderance of nonadditive gene action for the characters namely, plant height, number of productive tillers, boot leaf length, panicle length, grain weight per primary panicle and grain yield ...
متن کاملevaluation of general and specific combining ability of rice lines
general and specific combining ability of five fertile male (lines) and two male sterile (tester) of rice were evaluated for 10 important morphological traits as well as yield and yield components in a randomized complete block design with three replications. results revealed that general combining ability effects were highly significant (p
