Seed protein traits of fasciated pea recombinants and the role of the mutant genes involved.

The protein traits of some fasciated and non-fasciated pea recombinants have been studied in the light of mutant gene actions and interactions. The results indicate that combinations of different mutant genes affecting morphological characters have indirect influences on the quantitative composition of seed flour proteins of the genotypes. At the level of single specific amino acids, there were drastic quantitative alterations. The results also indicate that differences in the mutated background genotypes may have a role in the protein quantitative alterations. Correlations among protein and yield' traits have been calculated and discussed. Percent crude protein was found to be negatively correlated with different protein yield traits at the plant level.
