常规早稻高产、抗病、优质新品种引进及选育课题自1992年立题开始开展系统选育,1995年正式开始进行杂交育种。本课题研究旨在引进或选育单产比目前我省早籼稻主栽品种嘉育293增产5%以上,或单产与嘉育293相仿,外观米质优,食味品质佳,较抗稻瘟病、白叶枯病和纹枯病,苗期较耐寒,成熟时不过易落粒,熟期与嘉育293相仿的早籼新品种。并推广应用于农业生产。 Conventional early rice high yield, disease resistance, quality introduction of new varieties and breeding topics since 1992, the system began to carry out systematic breeding, formally began in 1995 hybrid breeding. The purpose of this study is to introduce or select more yield than the current indica rice varieties in our province Jiayou 293 yield more than 5%, or similar to the yield and Jiayu 293, the appearance of high quality rice, good quality food, rice blast, white Leaf blight and sheath blight, seedling more resistant to cold, but easy to fall off when mature, mature and early indica rice varieties similar to the Jiayu 293. And promote the use of agricultural production.
