Linkage mapping of two mutant loci controlling leaf necrosis and glabrousness in chickpea (Cicer arietinum L.)

Published on Aug 17, 2018 12:02 PM

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.
