Abstract

Combining ability studies with respect to such green fodder quality characteristics as oxalic acid, calcium, sodium, potassium and green fodder yield were carried out in a 12 × 12 diallel cross set in pearl millet (Pennisetum typhoides (Burm) S. & H.). With regard to differential expression of gene effects, studies for quality traits were carried out in different seasons and on different plant parts. The relative proportions of general and specific combining variances indicated the preponderance of non-additive genetic variance. Parents possessing desirable fodder quality characteristics were identified on the basis of combining ability and per se performance, and selection criterion for crosses was discussed. It was recommended that leaf portion should be biochemically analysed and manipulated in an environment when the genes are expressed.

摘要

开展了 12×12 双列杂交设计的珍珠粟（Pennisetum typhoides（Burm）S. & H.）中草酸、钙、钠、钾和鲜草产量等绿色饲料质量特性的配合力研究。针对基因效应的差异表达，在不同季节和不同植物部位进行了质量性状研究。一般和特殊配合方差的相对比例表明非加性遗传方差占优势。根据配合力和自身表现鉴定了具有理想饲料质量特性的亲本，并讨论了杂交选择标准。建议在基因表达的环境中对叶片部分进行生物化学分析和操作。
