摘要:

【目的】分析海岛棉种质资源机采农艺性状,为机采海岛棉亲本选配和品种培育储备候选材料。【方法】选取125份零式果枝海岛棉种质资源为研究对象,对机采海岛棉农艺性状进行变异系数、遗传多样性、相关性、主成分和聚类分析。【结果】125份海岛棉种质资源间差异大,种质资源多样性丰富。12个性状变异系数在3.54%~23.85%,遗传多样性指数在1.96~2.10,株高与始果枝高度、始果枝节位、铃重呈极显著正相关,始果枝高度与始果枝节位、铃重呈极显著正相关,中部果枝长度与中部果枝夹角、下部果枝长度、下部果枝夹角,呈极显著正相关;12个机采海岛棉农艺性状转化为6个主成分累计贡献率达到了78.59%,分别为始果枝高度因子、果枝因子、茎粗因子、衣分因子、铃数因子和铃重因子;125份海岛棉种质资源分为五个类群,其中第Ⅴ类群机采性状表现良好,代表品种为新海43号、新海55号、石河子V7-4、K426、新78、16DJC01、新库K2442、新库198-1。【结论】125份海岛棉种质资源多样性丰富,第Ⅴ类群机采性好,获得了21份机采性好的海岛棉育种材料,可以作为创制机采棉的基础材料。

Abstract:

【Objective】 The agronomic characters of sea island cotton germplasm resources were analyzed in order to provide candidate materials for its parent selection and variety cultivation in the future. 【Methods】 125 sea island cotton germplasm resources with zero fruit branches were selected to analyze the coefficient of variation,genetic diversity,correlation,principal component and agronomic characters. 【Results】 Indicating that the 125 sea island cotton germplasm resources in this study had great differences and were rich in germplasm diversity.The coefficient of variation of 12 characters was between 3.54% and 23.85%,and the genetic diversity index between 1.96 and 2.10.The results of correlation analysis showed that there was an extremely significant positive correlation between plant height and initial fruit branch height,initial fruit branch node position and boll weight,extremely significant positive correlation between initial fruit branch height and initial fruit branch node position and boll weight,and extremely significant positive correlation between middle fruit branch length and middle fruit branch length. The length of the lower fruit branch and the angle between the lower fruit branch were significantly positively correlated,so it is necessary to consider each other and analyze comprehensively when cultivating cotton varieties picked by machine. By principal component analysis,the cumulative contribution rate of 12 agronomic characters divided into 6 principal components reached 78.59%,which were plant height factor,fruit branch factor,stem diameter factor,lint percentage factor,boll number factor and boll weight factor. The germplasm resources of sea island cotton were divided into five groups by cluster analysis. The fifth group showed good mechanical picking characters,and the representative varieties were Xinhai 43,Xinhai 55,Shihezi V7-4,K426,Xin78,16DJC01,Xinku K2442 and Xinku 198-1. 【Conclusion】 The 125 resources are rich in diversity,and the clustering analysis of the fifth group shoes that it has good machine-harvestability,and 21 breeding materials with good machine-harvestability were obtained,which could be used as the basic machine-picked materials.
