| 摘 要： | 研究了我国南方5省黄麻地方品种与产量和品质有关的12个数量性状的相关遗传进度与选择指数及其相对效率。结果表明:在一定的选择强度下,通过分枝高度间接选择单株干皮重的遗传进度最高,相对效率超过对单株干皮重的直接选择。对纤维支数的间接选择,仍以分枝高相对效率较高,但间接选择的效率不如直接选择的高。按单一性状选择指数计算单株产量的遗传进度,结果与相关遗传进度的研究完全一致;2个或2个以上性状选择指数计算的单株产量遗传进度都大于所含的单一性状;当选择指数方程包含了分枝高和单株干皮重后,即使再增加选择因素,其相对效率提高甚微。 |
| 关 键 词： | 黄麻 性状 相关遗传进度 选择指数 |

| Abstract: | It was investigated that the correlated genetic advances and selection indexes and their relative efficiency of 12 quantitative characters related to fibre yield and quality in jute varieties grown in southern China. The results showed that the highest genetic advance for dry bark weight per plant was predicated indirectly by branching hight, and its efficiency was higher than that by dry bark weight per plant itself. For fibre fineness, the highest genetic advance was predicated by fibre fineness itself, and the second by branching hight. The trend of genetic advances for dry bark weight per plant estimated by selection index with single correlated character agreed with that of correlated genetic, advances completely. There was little increase in relative efficiency of selection index by adding characte(s) to that including the branching hight and dry bark weight per plant. |
