甘蓝型油菜杂种优势和过氧化物酶的关系分析

Simple Analysis on the Relation of Heterosis and Peroxidase in Brassica napus L.

对3个甘蓝型油菜杂交组合和亲本的农艺性状表现及其与过氧化物酶活性的关系进行了浅析,研究结果表明:杂种的产量性状,如单株粒重、单株有效角果数、有效分枝数、主花序有效角果数等,比其双亲有明显的优势;杂种花期的过氧化物酶活性高于双亲,与株高、有效分枝数、有效角果数、千粒重等性状具有显著的相关性;杂种的过氧化物酶同工酶谱表现为双亲的互补型。

The relation of agronomic traits and pcroxidase in 3 hybrid combination and their parents of Brassica napus L. was analyzed. The result indicated the hybrids were superior to their parents in the yield traits, such as 1000- grain weight, the number of effective pods per plant, the number of effective branch and the number of effective pods in main anthotaxy. In florescence, the activity of peroxidase in hybrids was higher than in their parents and was in highly significant correlation with plant height, the number of effective branch, 1000-grain weight and the number of effective pods. The electrophoretic patterns of peroxidase in hybrids represented the complementary traits of their parents.
