Title: The improvement of radiation-induced Pisum mutants through recombination
Abstract: Gene gf (for greenish flower colour) and gene efr (for early flowering) of Pisum sativum were combined with other mutant genes of the genome. Their behaviour in different combinations was studied with regard to the seed production of the various recombinants. The following results were obtained: 1. Gene gf of mutant 189 was tested in 22 combinations. Some recombinant types, homozygous for gf, for genes for long or very long internodes and for stem fasciation, show a seed production of more than 800% of that of mutant 189. 2. Gene efr was tested in 59 combinations. The seed production of a high proportion of the recombinants studied was found to be essentially better than that of the parental genotype. This holds true for both long- and short-stemmed recombinants. 3. An early-flowering tendril-less super-dwarf shows high productivity partly due to the positive alteration of the pleiotropic pattern of gene efr. 4. The selection value of both the genes could be strongly improved by combining them with specific other mutant genes of the Pisum genome.
