Abstract
Variability, heritability, genetic advance and association of nine characters including yield in fifty F5 bulk lines of five wheat crosses viz. Kanchan×DSN-34 (1), Kanchan×YC-17 (2), Kanchan×YC-16 (3), Kanchan×BW-115 (4) and Kanchan×Ad-119 (5) were studied. All the characters studied e.g. days to anthesis, grain filling duration, spikes plant-1, plant height, grains spike 1, 100-grain weight, biomass plant-1, harvest index and yield plant-1 showed significant variation in all crosses. However, the expression of the traits in all crosses was not similar. Very high heritability and moderate genetic advance for days to anthesis and biomass plant-1 in crosses 1, 2 and 3 suggested the predominance of additive genetic variation for this two traits. Similar expression was observed for grain filling duration in crosses 1 and 2. Very high heritability and moderate to high genetic advance were observed for spike plant-1 in crosses 2, 4 and 5; plant height in crosses 1, 2 and 4; harvest index in crosses 2 and 3; grains spike 1 and yield plant-1 in all crosses. The heritability for 100-grain weight however, was moderate to high with low to very low genetic advance. Days to anthesis showed negative association with grain filling duration in crosses 1 and 3 and significant positive correlation with plant height, biomass plant-1 and yield plant-1 in cross 1 and with grains spike 1 in crosses 1 and 4. Grain filling duration showed mostly significant or non-significant negative correlation with all the traits with one exception where it showed significant positive correlation with 100-grain weight in cross 4. Spikes plant-1 and plant height showed significant positive correlation with biomass plant-1 and yield plant-1 in most crosses with few exception. The trait 100-grain weight did not show any significant correlation with any trait except in one occasion. Biomass plant-1 and harvest index showed significant positive correlation with yield plant-1 in most crosses, however, they did not show any significant correlation between biomass and harvest index.
