摘要: 【目的】海岛棉的熟性在不同区域差异较大,是品种选择优先考虑的因素。研究世界海岛棉熟性特征及其关联性状与生态因子的关系,为海岛棉熟性育种、针对性引种提供参考。【方法】2013~2016年,对218份世界海岛棉资源材料采用同一生态区连续集中种植的方法进行鉴定,研究其熟性和相关性状表现。【结果】综合考察各材料的主要农艺性状,其中亚洲地区的资源变异系数显著高于其他地区,果枝类型、始果节位、果枝数、单株铃数变异系数达到20%以上;熟性特征,材料间全生育期及各生育阶段差异显著,其中以蕾期变异数最大。比较熟性特征与主要农艺性状的关系,全生育期、蕾期、花铃期均与果枝类型、第一果枝节位呈高度正相关,零式、Ⅰ式果枝类型生育期较短,Ⅱ式、Ⅲ式果枝类型生育期较长。以熟性特征进行比较和分类,埃及材料>美国材料>中亚国家材料,中国新疆塔里木盆地材料和塔吉克斯坦、土库曼斯坦接近。不同地区来源的材料熟性与其育种地纬度、海拔呈极显著负相关,与无霜期、生育期内积温呈高度的正相关。根据熟性聚类可将海岛棉分为三个类群,与地理分布趋势一致。【结论】海岛棉熟性与果枝类型、始果枝节位高度正相关,与纬度、海拔显著负相关,中国新疆海岛棉和中亚零式果枝材料接近,从中亚国家引进熟性接近的品种更易获得成功。

Abstract: 【Objective】 The maturity of the island cotton is very different in different regions, which is a priority factor for selection of varieties. Understanding the characteristics of cotton maturity with its main related characters and ecological factors of the world sea-island cotton can provide reference for island cotton mature breeding and targeted introduction. 【Method】 218 island cotton varieties in the world were identified and analyzed by continuous centralized planting in the same ecological area from 2013 to 2016 and their maturity and related characters were studied.【Result】 The main agronomic characters of each material were comprehensively investigated, from which, we knew that the coefficient of variation resources in Asia was significantly higher than that in other regions, such as the type of fruit branch, the position of initial fruit node, the number of fruit branches and the number of bolls per plant. The coefficient of variation of resources in Asia was more than 20%. According to the characteristics of maturity, there were significant differences in the whole growth period and the growth stage among the materials, among which the variation in bud stage was the largest. The relationship between mature characters and main agronomic characters was compared. It was found that the whole growth stage, bud stage, flowering and boll stage were all related to the type of fruit branch, the first fruit branch was highly positively correlated with the node position, The growth period of fruit-branch type of type 0 and I was shorter while that of type Ⅱ and type Ⅲ was longer. According to the comparison and classification of maturity characteristics, it is found that the maturation of Egyptian material was higher than that of American material and the American type was higher than that of the central Asian country material, Xinjiang Tarim Basin material and Tajik, Turkmenistan are close to each other. Further analysis showed that the maturity of materials from different regions was significantly negatively correlated with latitude and altitude of breeding land, and positively correlated with accumulated temperature during frost-free period. According to mature clustering, island cotton could be divided into three groups, which was consistent with the geographical distribution trend. 【Conclusion】 The maturity of island cotton is positively correlated with the type of fruit branch and the height of branch of first fruit, and negatively correlated with latitude and altitude. Xnjiang island cotton is closed to 0 type of the central Asia countries, so the imported varieties from central Asian countries are more likely to be successful.
