OCCURRENCE OF CYTOPLASMIC-GENETIC MALE STERILITY IN SOME INDIAN SORGHUMS

Published on

THE development of cytoplasmic-genic male steriles has made hybrid Sorghum
a commercial proposition. Stephens and Holland (1954) found that Milo cytoplasm
interacted with Kafir nuclear factors resulting in male sterility; by substituting the entire
Milo genome with that of Kafir by repeated backcrosses, a hundred per cent. male
sterile line was developed. Subsequently, a number of male steriles have also been
built up by introducing genomes of appropriate
Sorghum varieties into Milo cytoplasm.
