estimation of heritability and heterosis of some agronomic traits and combining ability of rice lines using line × tester method
in order to determine combining ability, heritability and heterosis of some agronomic traits in rice, 4 pure lines were crossed with 2 cytoplasmic male sterile testers. parents and their f1 progenies arranged in rcb design with three replications. analysis of variance showed significant differences among genotypes for all traits, except for filled grains/panicle. furthermore, the crosses effect...
متن کاملEstimation of Combining Ability and Gene Action for Agro-Morphological Characters of Rapeseed (Brassica Napus L.) Using Line×Tester Mating Design
Combining ability effects were estimated for different agronomic characters in line × tester crossing program comprising 21 hybrids produced by crossing 7 lines and 3 testers. Parents and hybrids differed significantly for general combining ability (GCA) and specific combining ability (SCA) effects, respectively. The variance due to GCA and SCA showed that gene action was predominantly additive...
متن کاملCombining Ability Estimates for Yield Some Traits in Tomato (Lycopersicon esculentum L.) by Line×Tester
12 single crosses (F1) achieved by combining four testers and three commercial lines of tomato were evaluated for their response to water deficit stress and the combining ability of yield and some yield components. The layout was split plots according to randomized complete block design with three replications and three irrigation levels (FC, 60%FC and 40%FC). Crossing among lines and test...

متن کاملCombining Ability and Gene Action in Sunflower Using Line*Tester Method
In order to analyze general and specific combining abilities and gene effects in sunflower for some agronomic traits, five CMS lines and four restorer lines (tester) were crossed in a line × tester scheme. Hybrids were evaluated in a randomized complete block design with three replications in the Agriculture Research Station, University of Tabriz, in 2009 and 2010 growing seasons. Plant height,...
