本文用75—17,张亚1号,宁亚10号,天亚2号,681—3—3和77134—269,瑞士红7个胡麻品种(系)作亲本,采用完全双列杂交法(包括正反交和自交)49个组合,对胡麻含油率的配合力进行了初步分析。配合力方差分析表明:一般配合力和特殊配合力分别达11％和5％的显著水准,说明胡麻食油率的遗传受加性和非加性基因的共同作用,但加性基因效应是主要的。7个亲本当中,高油含量的张亚1号、75—17品种(系)的一般配合力效应居第一、第二位,低含油量的瑞士红和77134—2(?)一般配合力效应居末一、二位。特殊配合力效应值高的组合多数有一个一般配合力较高的亲本。含油率数值高(40％以上)的组合,至少含有一个含油率一般配合力高的亲本。
In this study, seven flax varieties (lines) 75-17, Zhang Ya 1, Ningya 10, Tianyao 2, 681-3-3 and 77134-269 and Swiss red were used as parents, Including reciprocal reciprocal and selfing) 49 combinations of oil content of flax with the preliminary analysis of the combining ability. The analysis of variance showed that the general combining ability and the special combining ability reached significant levels of 11% and 5%, respectively, indicating that the inheritance of flaxseed oil was affected by both additive and non-additive genes, but the additive gene effect was the main one . Among 7 parents, the general combining ability of Zhang Ya 1 and 75-17 with high oil content was the first and the second, with low oil content of Swiss red and 77134-2 (?) Force effect at the end of one, two. Most combinations with high specific combining ability have a parent with higher general combining ability. The combination of high oil content (over 40%) oil content contains at least one parent with high oil content and high combining ability.
