早籼“77—175”是我所一九七四年以珍珠矮为父本,红410为母本杂交培育而成的。于一九七七年稳定,一九七八年参加本所全省区试点试验,亩产898.5斤,居中熟组第一位。一九七九年我所试种1.29亩,平均亩产1232斤。一九八○年早季种植24亩,平均亩产810斤。晚季倒种28亩,亩产800.5斤。龙岩城关西安大队,一九七九年倒种,八月一日播种,十二日插秧,亩产1100斤。此品种一九八○年已在龙岩地区各县多点试种,很受群众欢迎。一般亩产800~900斤,高达千斤以上。在连续三年区试中,产量同对照种红410相似。但抗稻瘟病强,米质好,适
The early indica “77-175” was a result of the hybridization of the pearl dwarf maternal parent and the red 410 as the maternal parent in 1974. It was stable in 1977 and participated in the pilot project of the province in 1978 with a yield of 898.5 kg per mu, ranking the first among the middle class. In 1979, I tried to cultivate 1.29 mu, average mu produce 1232 jin. In the early 1980s, 24 mu were planted, yielding an average of 810 kilos per mu. Late seeding 28 acres, 800.5 kg per mu. Longyan Chengguan Xi’an Battalion, 1979 kinds of seeds, sown on August 1, 12 days transplanting, yield 1100 pounds. This variety in 1980 has been in Longyan counties to try more, very popular with the masses. General mu produce 800 ~ 900 jin, up to jin above. In three consecutive years of district test, the output is similar to the red 410. But strong resistance to rice blast, good quality rice, suitable
