寒地水稻种质资源品质性状特性及聚类分析研究
Study on Quality Characteristics and Cluster Analysis of Rice Germplasm Resources in Cold Region
摘要
Abstract
In order to breeding high quality rice in cold region ,clear rice germplasm resources quality character‐istics in cold region and provide theoretical basis for parent selection of rice quality breeding in cold region ,169 germplasm resources of rice in cold region were used as the experimental material ,variation analysis ,correla‐tion analysis and cluster analysis were carried out based on nine quality traits which were the brown rice rate , the polished rice rate ,the head rice rate ,the length and width of the rice ,the ratio of length and width of the rice ,chalkiness ratio in the rice grain ,amylose content and protein content .The result showed that the differ‐ence and variation among the quality characteristics of rice in cold region germplasm were abundant ;There was correlation between the quality characteristics ;the germplasm resources of rice in cold region was divided into six categories by cluster analysis ,the ratio of length and width of category I was longer and the chalkiness ratio was the zower ;the brown rice rate of category Ⅱ was the highest ,and the the ratio of length and width was the lowest ;amylose content of category Ⅲ was the lowest ;the polished rice rate and the head rice rate of cate‐gory IV were the highest ;chalkiness ratio of category V was the lowest ,and the ratio of length and width was the highest ;amylose content and protein content of category VI were the highest .关键词
