摘要
优异的稻种资源是水稻育种的物质基础,本文通过对引自云南的61份育种核心材料在宜春的适应性表现及其相关农艺性状的分析。主要结果如下:该61份材料在宜春自然光照条件下都能正常结实,平均结实率达82.5%,各农艺性状变幅及变异系数较大,显示出较好生态适应性和遗传多样性;以8个农艺性状表型值的综合聚类显示,可将该61份种质资源划分为7个类群;从总体看该批材料在宜春具有一定的感光性,生育期偏长,并从中筛选出11份优异种质资源,供后续育种利用。
The excellent rice germplasm is the foundation of rice breeding,in this paper,the fitness and the agronomic traits of 61 varieties which were external introduced from Yunnan province were analyzed. The results showed,all of those varieties can growth normally in the natural condition of Yichun city,and it＇s mean seeding setting rate reach 82. 5%,existed a good ecological adaptability and biodiversity,and it can be clustered into 7groups by phenotypic values of 8 agronomic traits. It＇s growth period showed relatively prolonged,and some photonasty. 11 species were screened and could be further useable.
