扬辐籼2号(原名381)由江苏里下河地区农科所利用~(60)Co-γ射线辐照IR1529-68-3-2的突变体选育而成。该品种具有杂交稻汕优63的高产水平,多抗质优,是一个综合性状较为突出的中籼稻新品种。1989年该品种在省中籼稻区试中增产显著,故提前进行生产试验和参加南方稻区区试。1991年4月由江苏省农作物品种审定委员会审定命名。 一、主要特征特性 (一)产量高 1988年参加江苏省中籼稻联鉴试验,产量居参试品种首位,10个试点平均亩产535.2千克,比对照南京11号增产18％,比汕优63增产5.6％。1989～1990年参
Yangyinxian 2 (formerly 381) was selected from the mutants of IR1529-68-3-2 irradiated by ~ (60) Co-γ-ray in the Lixiahe area of Jiangsu Province. The hybrid rice has the high yield level of hybrid rice Shanyou 63, which is a middle-late indica rice variety with more comprehensive characters. In 1989 the variety in the province of indica rice trial yield significantly, it is ahead of the production test and participate in the southern rice area test. April 1991 by the Jiangsu Provincial Crop Variety Approval Committee validated named. First, the main features (a) high yield In 1988 to participate in Jiangsu Province, indica rice Lianjian test, the yield ranks first in the varieties tested, 10 pilot average 535.2 kg per mu, compared with the control Nanjing 11 increased 18% over the Shanyou 63 Increase 5.6%. 1989 ~ 1990 years reference
