花生辐射突变体杂交后代主要性状的遗传变异和选种效果的研究

 对两个表现型稳定一致的辐射大突变体杂交后代及两个原品种的杂交后代进行了遗传变异规律和选种效果的研究。主要结果：1.大突变体杂交后代单株生产力等经济性状的广义遗传力、遗传进度都优于原品种的杂交后代。2.大突变体间杂交后代的选种效果优于原品种的杂交后代，大突变体间杂交中选株率占总中选株率的86.1%，比原品种间杂交的13.9%高72.2%，并已初步选出了有希望的品种（系）。

A STUDY ON GENETIC VARIATION AND SELECTIVE EFFECT OF PRINCIPAL CHARACTERS OF HYBRID PROGENIES OF MACRO-MUTANTS IN PEANUT(ARACHIS HYPOGAEA L.)

In order to make good use of macro-mutants, we have studied the law of genetic variation and selective effect on the hybrid progenies of original varieties and of two macro-mutants with steady phenotypes.The reshlts show that the hybrid progenies of the two experimental macro-mutants in the broad-sense heritability and the genetic advance of their main economical characters as well as the effect on selection are better than those of the hybrid progenies of the two original varieties.The selection rate from the macro-mutant hybrid progenies is 72.2% which in higher than that of the hybrid progenies of the two original varieties, and a new prospecting strain has been obtained.
