以30多年来新疆不同年代广泛种植、有代表性的17个大麦品种为供试材料,通过分析其产量及主要农艺性状研究了新疆大麦品种更替的演变规律。结果表明:近30年来新疆大麦品种的产量呈现逐渐增加的趋势,随着年代的更替新疆大麦品种在性状生育期、穗长、千粒重和有效分蘖数上呈现逐渐增加的趋势,而在性状穗密度、主穗粒数、主穗粒重及籽粒蛋白质含量上表现出逐渐降低的趋势;相关分析表明,17个品种的产量与生育期、穗长、千粒重和有效分蘖数相关系数较高。
In this paper, 17 barley cultivars, widely planted and cultivated in different decades in Xinjiang, were used as test materials. The evolution of barley varieties in Xinjiang was studied by analyzing their yield and main agronomic traits. The results showed that the barley cultivars in Xinjiang tended to increase in yield over the past 30 years. With the change of years, Xinjiang barley cultivars tended to increase in traits, spike length, 1000-grain weight and effective tiller number. However, , The number of main spike, the main ear grain weight and the grain protein content showed a decreasing trend. Correlation analysis showed that the correlation coefficients between yield and growth period, spike length, 1000-grain weight and effective tiller number of 17 cultivars were higher.
