| 摘 要： | 利用人工气候室,以相对受精率为耐热能力评价指标,对西南地区生产上大面积使用的62个杂交水稻品种进行抽穗开花期耐高温特性鉴定。筛选出相对受精率≥60%的品种9个,并通过聚类分析将62个杂交水稻品种分为耐热能力不同的3类,为水稻生产布局提供科学依据。

| Abstract: | Based on the relative spikelet fertility rate, 62 hybrid rice combinations were tested through artificial climate chamber appraisal at flowering stage in southwest China. There are 9 hybrid rice combinations be screened in the test,which relative spikelet fertility 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. |
