Abstract

Linkage analysis of two linked mutant loci controlling leaf necrosis (nee) and glabrous shoot (gl) was done with eleven isozyme loci in two F2 populations of chickpea (Cieer arietinum L.). The nee and gl loci were located closely linked to the isozyme locus Amy, 6.2 ± 1.8 eM and 15.4 ± 2.8 eM apart respectively, in a gene order of Amy-nee-gl. As the locus Amy is known to be located on linkage group VII, nee and gl loci were also assigned to this linkage group. The isozyme AMY can be used as marker for necrosis gene in segregating generations.
