浙207是浙江省农业科学院育成的常规高产早籼新品种,2009年2月通过湖南省农作物品种审定委员会审定。两年区试平均产量8.13 t/hm2,比对照金优402增产2.28%,全生育期111.8 d,比对照短0.9 d。表现出株型较紧凑,剑叶挺,分蘖力中等特征。其茎杆粗壮,抗倒性较强,穗、粒、重结构均衡,丰产性好,成熟时叶青籽黄落色好,稻瘟病抗性好于对照,适应性广。

Zhe207, early-maturing indica rice bred by Zhejiang Academy of Agricultural Sciences, was registered and released for commercial production in Hunan province in Feb. 2009. The characteristics of Zhe207 were as follows： compact plant type, strong stem, large panicles, fine grain quality, high and stable yield, good lodging resistance, good BLB resistance and wide adaptability. The average yield of regional trials was 8.13 t/hm^2 during two years （2007＆2008）, 2.28% higher than that of the check - Jinyou402; the average growth duration was 111.8 d in Hunan, 0.9 d shorter than the CK.
