20285系江苏省农科院粮食所从复虹3号×(辛尼斯×南粳15)的配组中选育出的早熟晚粳糯稻品种.练湖农场1980年引进品比试种,1981年扩种繁殖.(一)产量表现1980年在本场的省区试中折合亩产1130斤,占第一位,比对照筑紫晴1020斤增产10.8%.在省组织的16个优良品系联合鉴定试点中,实收亩产1114斤,居首位.1981年在本场的省区试点中,实收亩产1071.6斤,比对照筑紫晴756.7斤增产29.4%.在本场组织的新品系产量鉴定中,实收亩产1057斤,比对照复虹糯增产18.78%,两个试验产量都名列第一,均达到极显著增产标准.1981年我站示范繁殖21.1亩,实收亩产982斤,比筑紫晴增产20.6%.两年试种结果表明,该品种高产稳产,有较大的生产潜力和较高的经济收益.
20285 is a variety of early maturing late japonica glutinous rice bred from the compound group of Fuhong 3 × Xin’ning × Nanjing 15 by Jiangsu Academy of Agricultural Sciences Foodstuffs Institute. (1) Production Performance In 1980, the province held a trial of 1130 kg of mu per mu in the field, accounting for the first place, an increase of 10.8% over the control of Zishuang 1020 kg. In the provincial joint demonstration trial of 16 fine lines , The real yield per mu 1114 catties, ranking first in 1981 in the field of pilot in this field, the real yield 1071.6 kg, 756.7 kg compared with the construction of purple clear increase of 29.4% in the field of new strains of appraisal , The actual yield per mu 1057 kg, compared with the control complex Hong waxy yield 18.78%, the output of the two tests ranked first, have reached a significant increase in production standards .In 1981, I stand 21.1 acres of model breeding, real yield 982 kg per mu , 20.6% higher than that of Zishuangqing.The test results of two years show that the varieties have high and stable yield, large production potential and high economic benefits.
