基于同一度的云南甘蔗细茎野生种血缘F1代创新种质材料分类
Classification of innovation germplasm materials of Yunnan Saccharum spontaneum L. blood F1 generation based on degree of identity
摘要
Abstract
This research classified the innovation germplasm materials of Saccharum spontaneum L. blood F,, which originated from the semi-humid and semi-dry ecological environment in Yunnan Province, in order to provide scientific basis for iht: targeted use of innovation germplasm materials. [ Method ] For the innovation germplasm materials of 20 Saccharum spontaneum blood F[ generations, the tested material's 9 traits were individually investigated through the comprehensive evaluation method using set pair analysis of degree of identity. [ Result ]The 20 tested materials were classified into 10 types. Type I consisted of 8 germplasm materials with relatively good comprehensive performance, which accounted for 40% of the total number of tested materials; type II contained one germplasm material with extremely strong tillering and ratooning ability and low Brix; type Ⅲ included 2 germplasm materials with large number of millable stalks, extraordinarily high yield, and medium Brix; type Ⅳ included one germplasm material with high yield and Brix; type V included 2 germplasm materials with low tillering ability, low yield, and medium Brix; type VI included one germplasm material with thin stalk, low yield, and medium Brix; type Ⅶ included one germplasm material with extremely fine stalk, low yield, high Brix, no withered heart sprout rate, and possible drought resistance and borer resistance; type Ⅷ included 2 germplasm materials with thick stalk, high yield, and high Brix; type IX included one germplasm materials with thin stalk, high yield, and high Brix; lastly, type X has one germplasm material with thin stalk, low yield, and high Brix. [Conclusion]All germplasm materials show good tillering and ratooning ability and relatively large number of millable stalks. The use of different types of germplasm materials in moderation could possibly breed distinctive innovation parent materials, which could enormously enrich the hereditary basis of sugarcane breeding in China.关键词
