Fourtcen crosses involving seven fertile parents and four cytoplasmic male sterile testers having Texas male-sterile cytoplasm were tested at two locations. Ludhiana and Bajaura (Kulu Valley) for male-sterility behaviour.
The analysis of variance for pollen fertility at both the locations showed environment, genotype and genotype × environment interactions to be highly significant.
Composite J1 did not restore fertility to L 185T and T × 8T at both the locations while. other germplasms restored fertility in varying degrees at the two locations.
Possibilities of developing male-sterile and restorer lines simultaneously from composites have been discussed.
