Abstract:

Yixiang 101, derived from the fine quality CMS line Yixiang 1A and the heavy-panicle restorer line Gonghui 101, was bred by Agricultural Science Research Institute of Zigong city. In Sichuan territorial experimentation during 2004-2005, the average yield of Yixiang 101 was 8 189.85 kg/hm2, higher than Shanyou 63 by 6.78%. In the pilot productiion test in Sichuan province in 2005, the average yield of Yixiang 101 was 7 836.3 kg/hm2, higher than Shanyou 63 by 7.88%. Yixiang 101, which has the characteristics of fine quality, high yield, stably high yielding ability, strong resistance to diseases and adverses, is suitable for widely planting in the southern area of China. Yixiang 101 was approved through the validation of Sichuan province in April, 2006.
