Abstract:
Regional trials of new rice varieties in Fujian Province from 2007 to 2016 was briefly analyzed. The results showed that the regional trials in Fujian Province mainly included three type groups, i.e., the early rice group, the middle rice group and the late rice group, and further divided into different groups based on the maturity stage, varieties characteristics and the number of tested varieties, such as medium-maturing group, late-maturing group, high-quality group, special rice variety group, photosensitive group, Group A, Group B, Group C, etc. The number of tested varieties was 98-122 per year. The regional trial varieties tested in the first yield were largely eliminated, and most in the second year could enter into production trials. The tested varieties were mainly medium-or late-maturing, and mainly the hybrid rice varieties. The varieties with only one of the following characteristics, high-yield, high-quality or disease-resistant were common in the trial, but seldom the varieties with comprehensive characteristics of the above traits. The selection target of new rice varieties changed from one of the excellent properties to the comprehensive performance. Presently, the rice breeding was still carried out mainly in scientific research institutes, but tended to develop in scientific research units, enterprises and the cooperation of the both sides, and would be mainly in the enterprises for commercial breeding in the future. The tested varieties for regional trials were mostly provided by breeding organizations inside Fujian province, but the number of varieties from other provinces was increasing year by year.
