INHERITANCE OF GENETIC MALE STERILITY IN SAFFLOWER

Published on

A few male-sterile plants were identified in the accession crv-53 and in F2 population of
the cross A-I x 83-13-3 of safflower. Phenotypically, the male-sterile plants were identical
to male-fertile plants except for the nonfunctional pollen grains. The inheritance of male
sterility in both cases was found to be monogenic recessive. Crosses among the four
male-sterile sources showed allelic identity among MSN-l, MSV-1 and UC-148 male-sterile
lines, and all these were nonallelic to the GMS-5 (A) male-sterile strain.
