摘要
＇ Ji2055A＇ is a superior sterile line sorghum bred by Institute of Crop Resources, Jilin Academy of Agricultural Sciences. It has a growing season of 112 days and a plant height of 70 cm. With a stable sterility rate of 100%, ＇ Ji2055A＇ has a stable male sterility and highly viable stignms. Selfing won＇t lead to seeds, This sterile line is strongly resistant to drought and lodging in addition to resistance to leaf spot and head smut. Generally, it has a yield of 3 000 -4 000 kg/hm2 and the hybrid seed yield is between 4 000 - 5 000 kg/hm2, with a high combining ability. There are six varieties approved by the state and the province, as well as another eight new combines under regional testing. The obtained hybrids are strongly resistant, widely adaptable with a great potential to increase yield, ＇ Ji2055A＇ has promoted the breeding and production of spring early maturing sorghum in China.
