- 摘要:
- 以对大豆食心虫不同抗感材料 8004 、合丰 25、8604、1068 、9001、85164、黄宝珠和国育 100-4大豆品种(系)为亲本 ,组配抗×中(8004 ×合丰 25)、中×感(9001×85164)和感×抗(黄宝珠 ×国育 100 - 4)杂交组合,对 F 2 代性状的相关性[ x1]分析结果表明, 大豆食心虫虫食率与虫食粒数 、节数、单株粒数、单株粒重、百粒重和茎杆强度呈极显著正相关 。中 ×感(9001×85164)、感 ×抗(黄宝珠×国育 100- 4)杂交组合中虫食率与荚皮颜色呈极显著的正相关 ,在感 ×抗(黄宝珠 ×国育 100- 4)杂交组合中发现 ,虫食率与茸毛密度正相关性极强 。由此表明,矮杆主茎节数少 、单株粒数少、籽粒小、直立性强不倒伏 、荚皮颜色浅、茸毛密度小的大豆品种不利于大豆食心虫的产卵和危害,有降低虫食率的趋势。
- Abstract:
- T hree hybridized combinations of soybean, whose parents come from 8004 , Hefeng 25, 9001,85164, Huang Baozhu and Guoyu 100- 4, were studied on genetic variation of characters in F 2 generation.The results showed that the percentage of damaged seeds had significant positive correlation with the num-ber of damaged seeds , the number of nods in main stem , the number of seeds per plant , the seed weightper plant , the weight of 100 seeds and the intensity of haulm ;that the percentage of damaged seeds hadsignificant positive correlation with the color of pod coat in hybridized combinations of 9001 ×85164 andHuang Baozhu ×GuoYu100 - 4 ;that the percentage of damaged seeds had significant positive correlationwith the density of pubescence in hybridized combinations of Huang Baozhu ×GuoYu100- 4. So we couldmake a conclusion that the kind of soybean which had dwarf haulm , minor nods in main stem , small seeds,strong erect trait and lodging resistance , light color of pod coat , low density of pubescence , didn’t facili-tate egg deposition and damage of soybean pod borer ,and reduced the percentage of damaged seeds effec-tively.
