Sommario/riassunto

Genetic Enhancement of Rabi Sorghum - Adapting the Indian Durras presents both the historical background and the recent research done in breeding this important world crop for more global production. Its chapters cover topics in origin and taxonomy, morphology and breeding behavior, genetics, and cytogenetics, also looking at production, nutrition, and alternate uses.   The durra race is Ethiopian in origin and its introgression with wild forms permitted adaptation to drier conditions. These have migrated and adapted to the currently known crop that is cultivated in the winter season and com
