Combining 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 analysis for seed yield and its components in Sunflower (Helianthus annuus L.)
Twenty four lines were crossed with two testers in an L x T mating design to estimate the combining ability for seed yield in sunflower. Non-additive genetic variance played a preponderant role in the inheritance of all the characters studied viz., days to 50 % flowering, days to maturity, plant height, head diameter, volume weight, hundred seed weight and seed yield per plant. The lines 27, 43...
متن کاملcombining ability and gene action for agronomic traits and oil content in sunflower (helianthus annuus l.) using f1 hybrids
for different agronomic traits in sunflower (helianthus annuus l.) inbred lines were estimated using “line × tester” analysis method. six new restorer lines were crossed with four cms lines as tester in 2006 growing season. the 24 f1 single cross combinations were planted in complete randomized block design with four replications in khoy field research station in 2007 growing season. there were...
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,...
متن کاملCombining Ability Estimates for Yield and Fibre Quality Traits in Line X Tester Crosses of Upland Cotton, (Gossypium hirsutum)
This study was to estimate the GCA of the parents and SCA considered for the development of high yielding and better quality cultivars. Eleven genotypes and 28 F1 hybrids obtained by crossing 4 lines and 7 testers in line X tester mating system were sown in randomized complete block design. L X T analysis revealed significant GCA and SCA effects for all the traits except earliness. Among the pa...
