Abstract
Ten podfly resistant lines, i.e. PDA 93-1E, PDA 89-2E, PDA 88-2E, SL 12-3-1, SL 21-1-3, SL 21-6-2, SL 21-9-3, SL 22-2-3 and ICP 8102-5-S1, were crossed with each of 3 podfly susceptible cultivars, i.e. Bahar, ICP 5036 and T 7, in a line × tester mating design. MA2, PDA 93-1E, SL 21-9-3, Bahar and T 7 were identified as good general combiners for seed yield per plant, whereas SL 12-3-1, PDA 88-2E, PDA 93-1E, SL 22-2-3, ICP 8102-5-S1 and ICP-5036 were good general combiners for less pod damage and low sugar in pods. Besides, SL 12-3-1 was also a desirable general combiner for thickness of pod wall, total sugar and total phenols in pods. Heterosis of 73.77 and 168.42% over the standard control (Bahar) and better parent, respectively, were recorded for seed yield per plant. Five hybrids, i.e. MA 2 × Bahar, PDA 93-1E × T 7, PDA 93-1E × Bahar, SL 21-9-3 × T 7 and ICP 8102-5-S1 × T 7, exceeding above 45% standard yield heterosis, were spotted out as promising heterotic crosses.
