对332份云南糯玉米资源的表型多样性分析,结果为:①以来源和表型性状为依据,将云南糯玉米群体划分为5类6个生态型,91 27%的云南糯玉米品种属二季早和大玉米群,云南南部地区的糯玉米多表现为多穗性;②以变异系数为依据评价云南糯玉米品种间主要农艺性状的多样性,表现为:双穗率>穗位高>千粒重>株高>主茎叶片数>穗长>穗粗>生育期,营养成分表现为:α生育酚>硬脂酸>亚麻酸>脂肪=苏氨酸=色氨酸=赖氨酸>蛋白质=油酸;③筛选出231616、231712、230846、230596、231718、231979等一批农艺性状优异的云南糯玉米品种资源,231532、231268、231229和231185的多种营养成分含量均较高;通过上述研究,提出了云南糯玉米在育种、食品加工方面的利用方法和途径。
Based on the phenotypic diversity of 332 Yunnan waxy corn resources, the results were as follows: ① Based on the source and phenotypic traits, the waxy corn populations in Yunnan were divided into five types of six ecological types and 91.27% of Yunnan waxy corn genus The results showed that the diversity of main agronomic traits in waxy maize varieties in Yunnan was evaluated by the coefficient of variation. The results showed that: the rate of ear-ear> ear-height> 1000-grain weight> plant height> number of main stem leaves> ear length> ear diameter> growth period, the nutrients showed as follows: α tocopherol> stearic acid> linolenic acid> fat = threonine = tryptophan = lysine> Protein = oleic acid; ③Selected 231616,231712,230846,230596,231718,231979 and a number of excellent agronomic traits Yunnan waxy corn varieties resources, 231532,231268,231229 and 231185 a variety of nutrients are higher; through The above research, put forward Yunnan waxy corn breeding and food processing methods and ways to use.
