Abstract:

CGMS based hybrid breeding was found more reliable to give productive hybrids in pigeonpea but need some expansion. Therefore, in the present research, cytoplasmic male sterility (CMS) source from line AK-120-1A (A2 cytoplasm) was diversified into different height variant lines. These four height variant lines were combined with cytoplasmic male sterility through repeated backcrossing. Anthers of new CMS lines were white translucent colored that strongly correlated with complete male sterility without pollen grains. CMS lines showed difference in height, possibly controlled by different alleles of a gene. Two lines, Dwarf 45 cm and Dwarf 60 cm were early in the flowering and maturity. During the evaluation, Dwarf 45 cm and Dwarf 90 cm CMS lines found good for heterosis and for fertility restoration in combination with twelve restorer lines. Two hybrids Dwarf 45 cm x AKPR-344 and Dwarf 45 cm x AKPR-325 were found significant over the checks PKV-TARA and AKT-8811 for yield traits and found completely fertile. These dwarf lines showed good performance in hybrid combinations showing the prospects for future hybrid breeding.
