经对8个“天府”型花生杂交组合及相应亲本材料7个性状的遗传规律研究表明:(1)亲本对杂种后代的影响较大,各性状中亲值(双亲均数,后同)对F1—3代的平均遗传力为58.34～87.66%;(2)除单株产量和总果数外,其余株高、总分枝数、百果重、百仁重,出仁率5个性状在世代间的遗传力都高,一般在50%以上,最高达96.28%;(3)F2—4代单株产量的遗传力、以及各性状对产量的相关遗传力都很低或不稳定,进行直接单株选择或间接单株选择均无意义。
The genetic study on seven traits of 8 “Tianfu” type peanut hybrid combinations and their corresponding parental materials showed that: (1) the parents had a great influence on the offspring of the hybrids, and the parents (parents’ mean and the same) The average heritability of F1-3 generations was 58.34 ~ 87.66%. (2) In addition to the individual yield and total number of fruit, the other five characters of plant height, total number of branches, fruit weight, The heritability of each generation is high, usually above 50% and up to 96.28%. (3) The heritability of F2-4 generation per plant and the heritability of each trait to the yield are very low or unstable, There is no point in making direct or indirect plant selection.
