今年8月下旬,广东省农作物品种审定委员会召开了全省农作物品种审定会议。经审定合格的有6个水稻品种和1个小麦品种。“双桂1号”是广东省农科院水稻所遗传综合技术育种研究室选育成的。经1980、1981两年晚造省区域试验,比对照种“广塘矮”分别增产14.17％和19.37％。其主要优点是晚造早熟,可避过后期低温冷害,出米率较高,感染白叶枯病较轻。缺点是早稻苗期耐寒性较弱。适宜在我省南部作早稻栽培,中部如有防寒设备,可作搭配种用,晚稻可在中部偏北、中部及南部推广利用。
In late August of this year, the Guangdong Provincial Crop Variety Approval Committee held a meeting to examine and approve the province’s crop varieties. Approved by the six rice varieties and a wheat varieties. “Shuanggui No. 1” was selected from the Rice Research Institute of Genetics and Comprehensive Breeding of Rice Institute of Guangdong Academy of Agricultural Sciences. By 1980,1981 two provinces in the region to make late test, than the control species “Guangtangdi” increased by 14.17% and 19.37%. Its main advantage is that the late-made premature, can avoid late cold damage, a higher rate of rice, bacterial blight less susceptible. The disadvantage is that early rice seedling cold weaker. Suitable for early rice cultivation in the southern part of the province, if the central cold-proof equipment, can be used with the species, late rice can be in the central north, central and southern promotion and utilization.
