杂交中粳六优1号由江苏省农科院以六千辛A与77302—1配制而成。1985年引进我县试种,表现熟期适中,产量较高。当年试种7.7亩,平均单产为571.5公斤。1986年扩大示范种植4100多亩,平均单产达563.4公斤,比大面积种植的盐粳2号增产9.9％,其中连片种植的28.7亩丰产方,平均单产为594.5公斤。1987年在种源紧缺的情况下,我县种植面积仍达2793亩,单产为542公斤,比盐粳2号增产7.6％。三年种植情况表明,六优1号能在较大面积上产量稳定在550公斤左右,因而深得广大农户欢迎。根据三年来六优1号的考察资料,六优1号亩产550公斤的
Hybrid japonica Liuyou 1 by the Jiangsu Provincial Academy of Agricultural Sciences Liu Qian Xin A and 77302-1 preparation. Introduced in 1985 in our county trial, the performance of moderate maturity, high yield. 7.7 acres of trial that year, the average yield of 571.5 kg. In 1986, it expanded the demonstration planting area of 4100 mu with an average yield of 563.4 kg, an increase of 9.9% over that of the salt-tolerant Japonica 2 planted in a large area. The average yield of 28.7 mu of contiguous crop was 594.5 kg. In 1987, in the case of shortage of provenances, my county planted acreage still reached 2793 acres, yield of 542 kilograms, salt than Japonica 2 yield 7.6%. The three-year planting shows that Liuyou-1 can produce a stable yield of about 550kg in a large area, which has won the welcome of farmers.
