Abstract:

The development of Sichuan sorghum has entered a new and rapid period. Strengthening sorghum
breeding work is one of the most important ways to improve the development of sorghum industry. (1) The
industrial development and varietal utilization of sorghum in Sichuan had been overviewed in this paper.
(2) the ordinary seed breeding works of sorghum was lagged behind the breeding of hybrid sorghum and got few
cultivars, the seed breeding and propagation system began to lag, the ordinary seed breeding agencys were very
few, the sorghum seeds breeding bases were lagged behind the breeding bases of rice and corn, so it could not
adaptate the development of new condition. (3) The key to develop the sorghum industry of Sichuan lied in the
plan of consummating the base construction of sorghum seed. To increase the investment of sorghum seeds
breeding, make use of agricultural technology extension system, innovate investment mechanism, absorb the
societal funds, establish breeding bases, increase the investment of new sorghum seed breeding and promoting
by policies.
