| 摘 要： | 用6个抗虫棉亲本与6个常规棉亲本配置杂交组合,对其中的23个组合F1进行了杂种优势比较及相关分析,结果表明,强优势组合当首推K6×K5,其综合性状优良,次推B×K2和C×K1组合;单铃重与抗亲优势、中亲优势及竞争优势之间均达极显著水平的正相关,选择大桃品种作杂交亲本,是配置强优杂交组合的主要途径之一。

Comparison and Correlation Analysis for Heterosis of Pest- resistant Cotton Combinations |
| |
| Abstract: | Several hybrid cotton combinations were bred by crossing among six pest-resistant cotton varieties and six traditional cotton varieties, and F_1 generations of 23 hybrid combinations among them were studied by heterosis comparison and correlation analysis. The results showed that combination K_6×K_5 had the strongest heterosis and the best comprehensive traits, followed by combinations B×K_2 and C×K_1. There was significant positive correlation between single boll weight and anti-parental heterosis, mid-parental heterosis, competitive heterosis (P<0.01). So selecting big-boll cotton variety as crossing parent is the main approach to breeding hybrid cotton combinations with strong heterosis. |
