Yu Chuangyuan; Gan Shuzhen(Rice Research Institute, jiangxi Academing of Agricultural Sciences,Nanchang 330200)
In the recent years,a seriee of new rice varieties (combuiations) with different grainquality levels have been bred .out and greatly sped the development of high -yield,high-quality ,high-output agriculture of Jiangxi province. There are four features in Jiangxi's quality rice breeding.1 .employing both conventional methods and modern technolopy. 2. combining high- quality with highyield and multiple resistances. 3. developing both early rice and later rice,conventional variety andhybrid combination, mediuni - quality rice and super- high - quality rice coordinately. 4. paying greatattention to resource introduction and exploitation. In order to keep the leading role of Jiangxi's qualitybreeding, the breeding goais in the future should be: 1. combining high-quality with super-high-yield and multiresistances. 2. diveroifying breeding target according to grain usage. Finally thepossibility and character features for a yield of 9000kg. ha￣(-1) or more were discussed.
