摘要

本试验旨在通过x系试验分析，确定作为蛋白质来源的豌豆籽粒产量及相关性状的一般配合力和特异配合力及杂种优势。通过12 × 3系x试验分析，对籽粒产量及其遗传特性进行了研究。实验材料包括15个亲本及其36个杂交种。材料采用随机区组设计，每组重复3次。一般配合力和特异配合力效应均显著，表明存在加性型和非加性型基因作用。杂种优势被确定为优于中亲本和优亲本(HBP)。籽粒产量杂种优势在-36.29 ~ 8.77之间，相对杂种优势在-25.85 ~ 13.19之间。

Combining ability and Heterosis analysis for grain yield and yield associated traits in Pea (Pisum sativum L.)

This experiment was conducted to determine the general and specific combining abilities and heterosis for grain yield and yield associated traits in pea as a source of protein through line x tester analysis. Grain yield and its inheritance were carried out for investigation through a 12 x 3 line x tester analysis. Experimental materials comprising 15 parents and their 36 hybrids. The materials were planted in a randomized block design with three replications. The general combining ability and Specific combining ability effects were significant indicating the presence of both additive and non-additive types of gene actions. Heterosis was determined as the superiority over mid parent heterosis as well as better parent (HBP). Grain yield showed highly significant heterosis ranging from -36.29 to 8.77and relative heterosis ranged from -25.85 to 13.19 respectively.
