| 摘 要： | 浙辐 91 0系用浙辐 2 1 9与广东优质籼稻长丝软占杂交、杂种F1辅以 3 0 0Gyγ射线辐照处理后选育而成的早籼新品种。浙辐 91 0在湖南省湘潭市 1 997、1 998两年区试中 ,比对照品种湘早籼 1 3分别增产 6 4% (达显著水平 )和 6 9%。在浙江省金华市 1 997、1 998两年区试中 ,浙辐 91 0比对照品种浙 852分别增产 5 5%和 9 8% (达显著水平 )。已分别于 1 999年 1月和 2 0 0 0年 4月通过湖南省湘潭市和浙江省农作物品种审定委员会审定。经稻米品质分析 ,浙辐 91 0糙米的蛋白质含量达 1 3 2 % ,因此 ,它是一个高蛋白水稻品种。

BREEDING,CHARACTERIZATION AND APPLICATION OF A NEW EARLY SEASON INDICA RICE VARIETY ZHEFU 910 |
| |
| Abstract: | A new early season indica rice variety,Zhefu 910,was officially registered by the Municipal Crop Variety Registration Committee of Xiangtan,Hunan Province in 1999,and the Provincial Crop Variety Registration Committee of Zhejiang Province in 2000,respectively.It was bred by pedigree selection of a cross between an early season indica variety Zhefu 219 and a late season indica rice variety Chang\|si\|ruan\|zhan.The F\-1 dried seeds of this cross were treated with 60 Co γ\|rays at a dose of 300Gy before germination.In regional yield trials Zhefu 910 gained yield increase of 5\^5%～6\^4%(significant at 5% probablity) and 6\^9%～9\^8% over control in 1997 and 1998,respectively.Biochemical analysis revealed that the crude protein content of brown rice of Zhefu 910 was as high as 13\^2%.Therefore,Zhefu 910 could be also regarded as a high protein content rice variety.The main characteristics of Zhefu 910 and its cultivation techniques are describled in this paper. |
