Inducement of Minghui 63 early-maturing mutant and breeding of high-yielding early-indica hybrid rice Nongyou 90 |
| |
| Abstract: | Dry seeds of Minghui 63 were irradiated by60Co γ with the dosage of 350 Gy. From the M3 population, a mutant line named Zaohui 90 was obtained, which had uniform and stable agronomic traits as Minghui 63. The yield of Nongyou 90 of Nong A CMS line × Zaohui 90 was the highest during the early rice regional trials in Fujian Province in 1999 and 2000. Compared with Veiyou 64 and Veiyou 77 (CK), its yield increased by 9.8% and 8.0%, respectively, reaching significance level, and was superior to CK in disease resistance and rice quality. It was registered in 2002 by the Crop Cultivar Registration Committees of Fujian and Jiangxi Provinces, respectively. |
