Wheat is grown in rotation with rice on more than 9 million hectares in India. A number of problems are associated with the system and its sustainability is feared to be under threat. The Indian wheat program divides the country into five main zones, differentiated mainly by latitude and altitude. Wheat varieties are developed for each of these zones. A national cooperative testing program is well developed The breeding objectives are to obtain varieties with high, stable yield, with resistance to diseases, particularly leaf and stem rusts and leaf blights, and tolerance to abiotic stresses. More specific varietal and management recommendations, based on the particular requirements of the rice-wheat cropping system, have recently been developed
