西南杂交水稻抽穗开花期耐热性筛选
Screening of Heat Resistance at Flowering stage in Hybrid Rice in the Southwest China
摘要
Abstract
Based on the relative spikelet fertility rate, 62 hybrid rice combinations were tested through artificial climate chamber ap-praisal at flowering stage in southwest China. There are 9 hybrid rice combinations be screened in the test,which relative spikelet fer-tility rate are more than 60%. And the 62 hybrid rice combinations were classified into 3 groups with different heat resistance based on clustering analysis. These results can provide a scientific basis for rice production layout.关键词
