云南湿润生态型甘蔗细茎野生种血缘F1代创新种质材料同一度分类
Identical degree classification of humid ecotype thin-stalked Saccharum spontaneum L.F1 generation innovation germplasm materials in Yunnan
摘要
Abstract
[Objective]This research classified the innovation germplasm materials of humid ecotype Saccharum spontaneum L. Fl generation in Yunnan in order to provide scientific basis for improving the efficient utilization of F, generation innovation germplasm. [Method]By combining the theory of set pair analysis and the principle of fuzzy cluster, the identical degree analysis method was used to classify the nine main traits of 20 germplasm accessions of humid ecotype Saccharum spontaneum L. F1 generation in Yunnan. [ Result]The 20 germplasm materials of Saccharum spontaneum L. F1 generation were divided into 8 categories: category I included one material with medium seedling rate, low tillering rate, low amounts of effective stalks, slender stalk, low yield, and low brix; category Ⅱ included one material with high seedling rate and tillering rate, high amounts of effective stalks, high stalk rate, high yield, and high brix; category Ⅲ, which accounted for 40% of the total number of materials, included 8 materials with medium seedling rate, medium amounts of effective stalks, large stalk, and medium yield; category IV included one material with normal seedling rate, large stalk, high yield, and low brix; category Ⅴ included two materials with good seedling rate, medium tillering rate, high amounts of effective stalks, medium-large stalk, high yield, and relatively low brix; category Ⅵ included 5 materials with good seedling rate, medium-small stalk, high yield, and medium brix; category Ⅶ included one material with low seedling rate, low amounts of effective stalks, low yield, medium-large stalk, and medium brix; lastly, category Ⅷ included one material of normal seedling rate, high tillering rate, large stalk, low amounts of effective stalks, high yield, and medium brix. [Conclusion]Within the same category, the characteristics of Saccharum spontaneum L. F1 generation innovation germplasm materials were basically the same, but between different categories, the characteristic differences were significant. In the study of Saccharum spontaneum L. F1 generation innovation germplasm materials, different targeted types of germplasm materials with excellent characters were screened out, which reduced the resource utilization blindness in order to improve sugarcane resource breeding efficiency.关键词
