Estimates of additive, dominance vanance and expected advances front diflcrcnt methods of selection for grain yield were calculated accoiding to Design - 1 in the synthetic variety of maite. “Moshtobor-2”. Dala were collected on grain yield per plant (g). plant arid ear heights (cnt). number of rows per car. number of kernels per row and 100-kernel weight. The additive genetic variance was significant for plant and ear heights and number of rows per car However, the dominance variance was significan for most trails Moderate lo high heritability values were detected for all trails except 1(X)-kernel weight. The heritability values in narrow sense ranged from 66 21 for plant height to icro for 1(N) - kernel weight The predicted genetic advance per cycle for improvement the vaٌct under study using mass selection one six. modified car-to-row selection, half-sib family selection, full-sib family selection, progeny test and S1 family selection ere 2.57. 3.01. 7.53. 626. ،2.04 and X 79%. re,cctively. Progeny test and S1 family selection seem to be the best methods to improve the variety under study.
