Line X Tester Analysis Across Environments in Tomato

Combining Ability, Heterosis and Estimates of Genetic Components in Bacterial Wilt Resistant Genotypes

Beschreibung

Study was carried out at Palampur and Bajaura in India.7 lines, 4 testers & their 28 hybrids were evaluated in RBD with 3 replications in line x tester mating design. ANOVA revealed significant differences among genotypes and GxE interactions, the line x tester analysis revealed significant differences due to line x location, tester x location & line x tester x location interactions (tested against error mean squares) at both locations and pooled analysis for most of the traits. GCA effects revealed that the lines BT-18 and Rodade and tester Hawaii-7998 and EC-392698 at Palampur;lines BL-333 and CLN-2123 and testers EC- 191536 and EC-392698 at Bajaura were good general combiners for yield and its contributing traits. However, BT-18 and BL-333 among lines and EC-392698 and Hawaii-7998 among testers were good general combiners for maximum traits studied in over all pooled analysis. Based on combing ability, heterosis and mean performance, crosses BT- 18xHawaii-7998, RodadexEC-392698 and BL-333xEC- 191536 in overall pooled analysis had great promise for further exploration. Preponderance of non additive gene action was fond in most of the traits.
