Morphological features and inheritance of a dwarf -growth phenotype in a pea mutant line

A dwarf-growth pea mutant recovered after exposing seeds of P. sativum cv Iregi-5 to gamma-irradiation. The main characteristic of the plants was the shortened internode length. The shoot growth of the mutant was less than that of its parent. The line V/4 has shown to have single-gene recessive inheritance, characterized morphologically and for seed production. The early expression of the mutant phenotype makes it desirable characteristic for genetic- and physiological studies of the stem elongation and plant development.
