Abstract
Genetic analysis of the ineffectively nodulating radiation-induced chickpea mutants PM405 and PM796 revealed two new recessive, nonallelic root nodulation genes. In PM405, the m4 gene determined the formation of small white nodules; in PM796, the m5 gene determined the formation of nodules that were green except for a narrow band apparent leghemoglobin pigmentation near the nodule tip. Recessive epistasis was evident in crosses between PM405 and PM796. F2 segregation data fit the expected ratio of 9 wild type: 3 PM796 type: 4 PM405 type.This publication has 1 reference indexed in Scilit:
