| Abstract: | Tianlong 1A, derived from the cross of Basmati, an introduced fine quality rice, and H067, an indica-japonica derivative with maintaining ability, and the testcross of single plants selected from its F3 population to Feigai A, is a new CMS line developed by Mianyang Tianlong Rice Research Institute through the successive backcrossing method. It has compact plant type, strong tillering ability, stable male sterility, high outcrossing rate and good grain quality. Its hybrids show a strong heterosis in grain yield and a relatively early maturity. In August, 2004, it was technically identified in Sichuan Province. The hybrid Tianlongyou 140 (Tianlong 1A/Tianlonghui 140), a double-cropping late rice hybrid variety, was certified and released to commercial production in Hunan Province in 2009. |
