有关花生数量性状的遗传规律和主要性状的相关性,在育种技术上一般都凭经验。为了改进育种方法,提高育种效果,我们针对花生育种工作中存在的主要问题,结合选种材料,于1962-1963年,对杂种世代间的遗传力,以及杂种后代主要经济性状的相关性,进行了统计估算。供试材料:伏花生×莱阳大粒墩(正反交)为1960年的杂交后代。1961年培育子一代;1962年结合子二代的培育,研究杂种主要性状的相关性,1963年子三代除估算世代(F_2-F_3)间的遗传力外,还分析计算了性状间的相关性。(一)花生世代间(F_2-F_3)主要性状遗传力的研究利用上下代囘归及相关法估算遗传力,用世
The genetic law of peanut quantitative traits and the correlation of the main traits are generally based on experience in breeding technology. In order to improve the breeding methods and improve the breeding effect, we carried out the major problems in the peanut breeding work, combined with the selection of materials, and the correlation between the heritability of the hybrid generations and the main economic traits of the hybrid offspring from 1962 to 1963 Statistical estimates. Test materials: peanut × Laiyang large grain pier (reciprocal cross) in 1960 hybrids. In 1961, the first generation of youngsters was bred. In 1962, the second generation of hybrids was used to study the correlation of the main characters of the hybrids. In addition to the heritability of the generations (F_2-F_3) in 1963, the correlations between the traits . (A) Study on heritability of the main characters of peanut intergenerational (F_2-F_3) Heritability was estimated by regression of the upper and lower generation and correlation method,
