The study was carried out during Rabi season of 2019-20 at HAREC, Bajaura Farm, to evaluate genetic variability for yield and yield related traits in two hundred ten barley germplasm lines (144 exotic and 66 indigenous) and six standard check varieties [HBL 113 (Vimal), HBL 713 (Him Palam Jau 1), HBL 804 (Him Palam Jau 2), BHS 400 (Pusa Sheetal), BHS 352 (Himadri) and VLB 118 (VLJau 118)] in Augmented Design. The analysis of variance indicated significant difference among entries (ignoring blocks), checks, varieties and checks v/s varieties for all quantitative characters except peduncle length in case of checks vs. varieties. The mean squares due to blocks were non-significant for most of the characters under study except for peduncle length (cm), plant height (cm) and days to 75% maturity. High values of PCV and GCV (>20%) were observed for grain yield/plant, number of effective tillers/plant, biological yield/plant and number of grains/spike in this set of experimental barley genotypes indicating high response to selection. High heritability coupled with high genetic advance as per cent of mean was observed for number of grains/spike, biological yield/plant and grain yield/plant, indicated their importance for grain yield improvement in barley.

Abstract


The study was carried out during Rabi season of 2019-20 at HAREC, Bajaura Farm, to evaluate genetic variability for yield and yield related traits in two hundred ten barley germplasm lines (144 exotic and 66 indigenous) and six standard check varieties [HBL 113 (Vimal), HBL 713 (Him Palam Jau 1), HBL 804 (Him Palam Jau 2), BHS 400 (Pusa Sheetal), BHS 352 (Himadri) and VLB 118 (VLJau 118)] in Augmented Design. The analysis of variance indicated significant difference among entries (ignoring blocks), checks, varieties and checks v/s varieties for all quantitative characters except peduncle length in case of checks vs. varieties. The mean squares due to blocks were non-significant for most of the characters under study except for peduncle length (cm), plant height (cm) and days to 75% maturity. High values of PCV and GCV (>20%) were observed for grain yield/plant, number of effective tillers/plant, biological yield/plant and number of grains/spike in this set of experimental barley genotypes indicating high response to selection. High heritability coupled with high genetic advance as per cent of mean was observed for number of grains/spike, biological yield/plant and grain yield/plant, indicated their importance for grain yield improvement in barley.
