摘 要:为了客观评价小麦品系的主要性状,为区域试验和生产试验提供依据,对3份较为稳定品系的产量、农艺性状、品质性状进行方差和相关性分析,结果表明,供试品系的产量均比对照(永良4号)高,但无显著性差异。农艺性状与产量的相关程度依次分别为:芒长(0.254)>主茎穗长(0.189)>有效分蘖数(0.171)>结实小穗数(0.122)>单穗粒数(0.111)>不孕小穗数(0.109)>单穗粒重(0.032)>株高(-0.040)>韧度(-0.063)>千粒重(-0.216)>粒径(-0.620)。籽粒硬度、沉淀值、湿面筋含量、干面筋含量、容重与产量呈弱的负相关。农艺性状与品质性状间无显著相关性,只有株高和容重呈显著负相关。品系07-1的农艺性状和品质性状较好。In order to evaluate wheat main characters and provide helpful information for the regional and pruductioin tests,variance and correlation analysis were used for agronomic and quality characters in three wheat lines and Yongliang4(CK).The results indicated that the yield of the three wheat lines were all higher than that of Yongliang4,while the differences among them were not significant.Correlation of agronomic characters to the yield was presented below: awn length(0.254) main ear of long(0.189) effective tiller number(0.171) fruiting spikelets number(0.122)each ear of number of seeds(0.111) sterile spikelets number(0.109) seeds weight of each ear(0.032)plant height(-0.040)toughness(-0.063) 1000-grain weight(-0.216) diameter of seeds(-0.620).The yield presented significantly feeble negative relation to quality characters such as kernel hardness,sedimentation value,wet gluten content,dry gluten content,and test weight.The height and test weight presented significantly feeble negative relation,the other agronomic characters have no significantly correlations with quality characters.The lines 07-1 is better than others in agronomic and quality characters.
