冈稻02系我所于1969年从迟熟晚粳嘉农14中选出的变异株系。它的形态特征与嘉农14相似,但成熟期早7天左右。当年冬季参加南繁,1970年起,经鉴定、繁殖、示范结果,产量高于沪选19,也较农垦58增产;成熟期与沪选19相似,较农垦58早10天左右。因其具有早熟稳产特点,适宜于我区水田三熟栽培,也有利于绿肥高产。现将几年来的试验示范结果整理如下。
Okamoto 02 is a mutant strain that was selected by our institute in late maturity late japonica Jianyou 14 in 1969. Its morphological characteristics and Jiaonan 14 similar, but about 7 days early maturity. In the same year, it participated in Nanfan in winter. Since 1970, the result of identification, breeding and demonstration showed that the output was higher than that of Shanghai election 19 and also increased than that of Nongken 58; the mature period was similar to Shanghai election 19 and about 10 days earlier than that of Nongken 58. Because of its characteristics of precocious stable, suitable for paddy cultivation in our region, but also conducive to high-yield green manure. Now the results of several years pilot demonstration as follows.
