摘要

对18个大麦品种进行了连续2个rabi作物季的环境互作基因型(GEI)评价，以确定高产稳定的大麦品种。AMMI分析显示，基因型(G)、环境(E)和GEI分别占总方差的1672.35、78.25和20.51。在AMMI双图分析的基础上，DWRB 137 (41.03qha-1)、RD 2715 (32.54qha-1)、BH 902 (37.53qha-1)和RD 2907 (33.29qha-1)的产量分别比农户再生品种(24.43qha-1)高出64.45%、30.42%、50.42%和33.42%。

Using AMMI approach to delineate genotype by environment interaction and stability of barley (Hordeum vulgare L.) genotypes under northern Indian shivalik hill conditions

Genotype by environment interaction (GEI) of 18 barley varieties was assessed during two successive rabi crop seasons so as to identify high yielding and stable barley varieties. AMMI analysis showed that genotypes (G), environment (E) and GEI accounted for 1672.35, 78.25 and 20.51 of total variance, respectively. Partitioning of sum of squares due to GEI revealed significance of interaction principal component axis IPCA1 only On the basis of AMMI biplot analysis DWRB 137 (41.03qha–1), RD 2715 (32.54qha–1), BH 902 (37.53qha–1) and RD 2907 (33.29qha–1) exhibited grain yield superiority of 64.45, 30.42, 50.42 and 33.42 per cent, respectively over farmers’ recycled variety (24.43qha–1).
