Abstract
The major aim of pearl millet breeder is to develop stable, high-yielding varieties/hybrids. The improved composite/ population provides base for the development of high-yielding stable varieties/hybrids. The present study was conducted to compare the efficiency of half-sib (H5), full-sib (F5) and selfed progeny (51) recurrent selection methods for improvement in yield: and to improve the per se performance of the EC91 PCV5 pearl millet composite. Half sib progeny selection method showed 3.17% realized genetic gain, whereas full-sib progeny selection method showed 11.49% and 51 progeny selection method showed 31.6% realized genetic gain for grain yield on pooled basis. Thus, 51 progeny selection method recorded highest realized genetic gain for grain yield as compared to half-sib and full-sib progeny selection methods. 5imilar trend was also observed for other yield contributing traits. For effective tillers per plant the realized genetic gain was 12.55% for half-sib, 25.11% Jor full-sib and 28.14% for 51 progeny selection method. It was 0.61% (H5), 3.55% (F5), 7.69% (51) and 0.16 % (H5), 16.06% (F5) 28.04% (51) for threshing percentage and harvest index, respectively on pooled basis. Thus, it was revealed. that the 51 progeny selection method is most efficient for improvement in grain yield and its contributing traits in pearl millet. The increase in grain yield in 51 progeny selection method is correlated with increase in panicle surface area, effective tillers per plant threshing percentage and harvest index. On the other hand, for dry fodder yield, only half-sib progeny selection recorded significant realized genetic gain. This increase in dry fodder. yield is correlated with the tallness and lateness.
