国内外有不少学者研究花生主要经济性状的遗传变异及其在品种改良上的利用价值,对其主要性状的表型变异和遗传变异作了不少报道,但对苗期主要性状报道较少。1981年我所以花生四大类型具有代表性的12个品种作试验材料,进行花生苗期10个性状遗传变异在育种上的意义,及其与产量相关性的研究。本文报告苗期10个主要性状遗传变异、遗传进度的研究结果,供育种实践的参考。
Many scholars at home and abroad have studied the genetic variation of peanut’s main economic traits and their utilization value in breed improvement. They made many reports on the phenotypic variation and genetic variation of their main traits, but few reported the main traits . In 1981, we used the representative 12 varieties of peanut as experimental materials to study the significance of genetic variation of 10 traits in breeding at peanut seedling stage and its correlation with yield. This paper reports the seedling 10 main traits of genetic variation, genetic progress of the research results, for breeding practice reference.
