为持续发展我省水稻生产,继续主攻中稻的同时,积极创造条件在气候适宜的地区发展双季稻,省农科院水稻所从全年品种熟期配套、高产稳产的目标出发,最近培育出该所第一个早稻早中熟良种“1107”,给两季稻连作高产提供了一项重要的有利条件和有效措施。“1107”是用曾著名全国的推广良种“珍株矮”和“二九青”杂交选育而成,1977年定型后至今,连续参加三年品比试验、一年川东南多点试验示范和三年全省早稻区域试验。表现具有较广泛的适应性和对年际间气候差异的适应力与稳产高产性能。综合
In order to continue to develop rice production in our province and continue to focus on medium-sized rice, we will actively create the conditions for the development of double-cropped rice in a climate-friendly area and the provincial Academy of Agricultural Sciences, starting from the goal of supporting mature varieties and producing high and stable varieties throughout the year, The first early-maturing early hybrid rice “1107” provided an important favorable condition and effective measure for continuous production of two-season rice. “1107” was bred from the crossbreeds of “Zhenzhengdai” and “Nojiqing”, which have been the famous popularized varieties throughout the country. Since stereotyped in 1977, they have continuously participated in the three-year ratio test and one year in Southeast Sichuan And three years the province’s early rice regional trials. It has a wide range of adaptability and adaptability to inter-annual climatic differences and stable and high yield performance. Synthesis
