Abstract
The Indian millet (Pennisetum typhoides) hybrid breeding programme received a setback in 1965 through the high Sclerospora graminicola susceptibility of the female parent Tift 23 A, common to all 5 hybrids which had been released. Mutational rectification of the fertile counterpart of the male sterile line using gamma radiation permitted the development of a tolerant line which could replace the female parent. Simultaneous diversification of resistance using West African and India donors in the backcrossing programme permitted the release of 3 more male steriles (5054 A, 5141 A and L111 A) which are as widely adapted as the parental line. The corresponding selection for resistance in the male parents of the released hybrids resulted in a set of new reconstituted hybrids now cultivated in > 4 million ha in all the millet growing states in India, and which combine mildew resistance with all the desirable agronomic features of earlier hybrids
