Assessment of barley genotypes as maintainers and fertility restorers

Among the hybrids developed using male sterile line msml, three pollen parents BH 75, BH 85 and Bonlra 10 were found good fertility restorers as the per cent seed set in the hybrids produced by these pollen parents was 86.03, 88.98 and 80.90 and 20 pollen parents were observed to be maintainers as the per cent seed set ranged from 0.00 to 0.55. Among the 30 pollen parents used to produce the hybrids with msm2 male sterile line, eight pollen parents viz. BH 75, BH 85, BH 326, DL 100, ICARDA 105, PL 424, Bonlra 10 and UBE 380 restored more than 90 per cent fertility genes and ten parents maintained sterility. Thus these male sterility g:mes present in male sterile lines msml and msm2 can be transferred in maintainer lines to develop desirable male sterile lines.
