浙辐802是我所与浙江农业大学协作,于1980年选育而成的早籼新品种。它具有早熟、高产、抗病、省肥、秧龄弹性大、适应性广等优点。该品种1978年进行种子处理,1980年定型,至今仅4～5年时间,已在长江中下游8省1市推广,面积达1100万亩。这在新品种的选育推广上速度之快是前所少有的。它之所以有如此惊人的速度,除浙辐802本身的优良特性外,在育种程序上进行了改革。这就是一切以早出成果、早收效益为出发点,加速、加强了中间试验环节,既抓良种、又抓良法、还抓种源,数管齐下,才有今天的结果。现将这方面的做法与体会简述如下:
Zhejiang Spoke 802 is a new breed of early indica that was bred in 1980 by our cooperation with Zhejiang Agricultural University. It has a precocious, high yield, disease resistance, fertilizer, seedling age flexibility, wide adaptability and so on. The variety of seed processing in 1978, stereotypes in 1980, so far only 4 to 5 years, 8 provinces and 1 cities in the middle and lower reaches of the Yangtze River to promote an area of 1100 mu. This is the new breed of breeding promotion speed is rare. The reason why it has such an alarming rate, in addition to the excellent characteristics of Zhejiang spokes 802 itself, the breeding program was carried out on the reform. This is the starting point for accelerating and strengthening the pilot program of early achievement and early return of benefits. It not only grasps good seeds and grasps good laws, but also grasps the provenance with a few measures in place to achieve today’s results. The practice and experience in this respect are summarized as follows:
