Abstract:

【Objective】 To screen out high-yield spring wheat varieties suitable for planting and promotion under rain-fed agriculture conditions in Xinjiang. 【Methods】 The chlorophyll content, agronomic traits and yield of 32 spring wheat varieties were determined, and the drought tolerance of spring wheat in Xinjiang was comprehensively evaluated by analysis of variance, correlation analysis, principal component analysis and cluster analysis. 【Results】 The chlorophyll content of Xinchun 44 was the highest, which was 11.92% higher than that of the control variety Xinhan 688. The coefficient of variation of the main quantitative traits of spring wheat ranged from 6.18% to 28.75%, and the four indexes of actual yield, biomass per plant, number of infertile spikelets and 1000-grain weight had rich genetic variation and great potential for improvement. The highest yield of Xinchun 44 was 6,174.76 kg/hm2, which was 82.04% higher than that of the control variety Xinhan 688.There was a significant positive correlation between the yield and 1000-grain weight (P< 0.01), which were significantly positively correlated with the number of grains per panicle and stem length under panicle (P< 0. 05). At the genetic distance of 12.5, it was divided into five major groups, and the traits of each group were significantly different, and the number of grains per spike and the yield of group II Xinchun 44 were significantly higher than those of other groups. 【Conclusion】 Considering comprehensively, it is considered that Xinchun 44 has the strongest drought tolerance and is suitable for planting and promotion in the dryland of Xinjiang. After comprehensive consideration, it is believed that Xinchun 44 drought resistance is the strongest and is suitable for planting and promotion in dry land in Xinjiang.

摘要:

【目的】 筛选出适合新疆旱作区种植和推广的春小麦高产品种。【方法】 分析32个春小麦品种叶绿素含量、农艺性状以及产量之间的差异,并利用相关性、主成分和聚类分析等方法综合评价新疆春小麦耐旱性。【结果】 新春44号叶绿素含量最高,较对照品种新旱688提高11.92%;春小麦主要数量性状变异系数为6.18%~28.75%,实收产量、单株生物量、不孕小穗数和千粒重4个指标遗传变异丰富,改进潜力很大;新春44号产量最高为6 174.76 kg/hm2,较对照品种新旱688增产82.04%;实收产量与千粒重呈极显著正相关(P <0.01),均与穗粒数和穗下茎长呈显著正相关(P <0.05);在遗传距离12.5时分为5大类群,各类群性状差异明显,其中第Ⅱ类群新春44号的穗粒数和产量显著高于其他类群。【结论】 新春44号的耐旱性最强,适宜在新疆旱作区种植及推广。
