Diverse and stable male sterile tropical Asian maize inbred lines provide strategic opportunities for hybrid development.

ABSTRACT: Cytoplasmic Male Sterility, a maternally inherited trait which suppresses the production of viable pollen, eliminates the need for detasseling of females in hybrid maize seed production. A set of 88 diverse elite CIMMYT Asia maize inbred lines converted to CMS-C using a temperate donor, were evaluated for stable per se performance for grain yield, male sterility and Turcicum Leaf Blight resistance. Performances of CMS maize hybrids of varied genetic backgrounds across diverse environments -- seasons, years, agroecologies, countries, abiotic- and biotic stresses -- established a stable and robust diversification process which included the identification of potential maintainers and restorers that will benefit researchers, the seed industry and farmers. While multiple CMS hybrids showed a ra
