摘  要：
Jufeng 2A, an early middle-season indica line of cytoplasmic male-sterility, was developed through backcross method using Yiling 1A(recurrent parent) and the desirable progenies from the cross of a quality line 9526 as the maternal parent and Yiling 1B as the paternal parent. This cytoplasmic male-sterile line was characterized as heat-resistance, high out-crossing rate, good combining ability, and exhibits nicely-colored mature performance in its hybrid F1 s, so it was of a potential wide application in the research field of hybrid rice. Finally, Jufeng 2A passed the identification at site and assessment by the Hubei Crop Variety Approval Committee in August 2014, and had been approved for release in Hubei province in 2015.
