| 摘 要： | 利用5个高粱(Sorghum bicolor)不育系和6个饲草高粱恢复系(IS722为对照)为材料组配置30个杂交组合,采用不完全双列杂交(NCⅡ)设计法对其生物产量、株高、茎粗、分蘖和干重5个主要农艺性状数据进行了遗传力估算和配合力分析。结果表明,所有饲草高粱恢复系中,只有安微草3和053423-2在5个性状上的一般配合力都表现出正向效应,尤其在生物产量等性状上表现出较好的一般配合力。TX623A/053423-2、SX14A/053423-2和SX14A/(MamaMama/BMR)-1等9个组合的生物产量特殊配合力效应值高于对照IS722,表现出较高的特殊配合力。(MamaMama/BMR)-1的株高和干重效应值均位居第1位,表现出较高的一般配合力。V4A/健宝-8-2、HC356A/安徽草3、SX14A/皖系3SM3-1、SX7A/安徽草3和V4A/(MamaMama/BMR)-1在产量性状上表现出较高的特殊配合力,是较好的杂交模式。5个农艺性状的遗传是受加性和非加性效应双重影响,占主导地位的是加性效应。综合而言,(MamaMama/BMR)-1和053423-2表现出的一般配合力突出,安徽草3的特殊配合力表现较好,都是选育出的优良亲本恢复系。本研究对饲草高粱恢复系配合力和遗传力进行了估算,对了解饲草高粱恢复系主要性状的配合力,及为杂交育种选择优良亲本和最优杂交组合提供依据。

| Abstract: | 30 hybridized combinations from 5 sterile lines and 6 restoring lines (IS722 by CK) were used to analyze the heritability and combining ability of 5 agronomic characters with a p×q incomplete diallel cross (NCⅡ) design. The results were as follows:among all the restorer lines tested,only 053423-2 showed positive effect on the 5 traits,especially for the general combing ability (GCA) in biological yields.The 9 combinations derived from TX623A/053423-2,SX14A/053423-2 and SX14A/(MamaMama/BMR)-1 etc.exhibited significant specific combing ability (SCA)and exceeded to IS722.General combing ability of (MamaMama /BMR)-1 in plant height and dry weight were significant and the highest.The combinations V4A/Jianbao-8-2,HC356A/An hui cao No.3,SX14A/Wan xi 3SM3-1,SX7A/An hui cao No.3 and V4A/(MamaMama /BMR)-1showed high biological yield.The results indicated that the 5 agronomic traits were controlled by both additive and non-additive effects,and the additive effects were the principal one. Comprehensive,(MamaMama/BMR)-1 and 053423-2 showed good general combining ability,An hui cao No.3 showed good special combining ability,they are the ideal restoring lines. The heredity of the five traits was in fluenced by the dual influence of both additive effect and non-additive effects, but the additive effect is dominant.The study by means of combining ability and heritability estimates of forage sorghum restoring lines,to understand the combining ability of forage sorghum restorer main characters,and cross breeding of choosing excellent parents and provides the basis for the optimal hybrid combinations. |
