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 کاملAn estimation of the combining ability of barley genotypes and heterosis for some quantitative traits
ABSTRACT- Barley (Hordeumvulgare L.) is one of the most important cereals in the world which is used as human and cattle feed and for malt production. One of the most important steps in a hybrid and selection breeding program of barley is the selection of suitable parents with high general (GCA) and specific combining ability (SCA) for grain yield. In order to estimate the combining ability and...
متن کاملCombining Ability of Different Agronomic Traits and Yield Components in Hybrid Barley
Selection of parents based on their combining ability is an effective approach in hybrid breeding. In this study, eight maintainer lines and nine restorer lines were used to obtain 72 crosses for analyzing the general combining ability (GCA) and special combining ability (SCA) for seven agronomic and yield characters including plant height (PH), spike length excluding awns (SL), inter-node leng...
متن کاملGenetic Expression of Yellow Rust Resistance, Yield and Yield Related Traits in Wheat Using Griffing's Combining Ability Analysis
Knowledge of traits inheritance is a prerequisite for any plant breeding program. Wheat cultivars like Pirsabak-85, Khyber-87, Saleem-2000, Pirsabak-04, Pirsabak-05 and Shahkar-13 were crossed in 6 × 6 half diallel fashion during 201011 at the Cereal Crops Research Institute (CCRI), Pirsabak Nowshera, Pakistan. The F1 and F2 half diallel hybrids in comparison with parental genotypes were studie...
متن کاملCombining Ability of Pod Yield and Related Traits of Groundnut (Arachis hypogaea L.) under Salinity Stress
A study was performed using 6 × 6 F1 diallel population without reciprocals to assess the mode of inheritance of pod yield and related traits in groundnut with imposed salinity stress. Heterosis was found for pod number and yield. Data on general and specific combining ability (gca and sca) indicated additive and nonadditive gene actions. The gca: sca ratios were much less than unity suggesting...
