一、“8706”以“78130”为母本与“温抗3号”杂交,1987年春定型的新品种。 1987年早季本所品比,3月18日播,4月19日单本插,6月13日齐穗,7月11日成熟,全生育期115天,比“金早6号”早熟6天。1988年本所示范4.25亩,3月16日播种,4月24日插秧。6月10日始穗,14日齐穗。抽穗期比“78130”早5天,比“红410”迟1天。 87年单本小区测产,亩产334.06公斤,比“金早6号”减3.82％,方差分析不显著,大区单本繁殖亩产403.3公斤。株高89厘米,株叶态好,分蘖强,纹枯病轻,后期熟色青枝腊秆。单本插亩有效穗19.6万,每穗103粒。结实率96.0％,千粒重 First, the “8706” to “78130” as the female and “Wen Kang No. 3” hybrid, spring 1987 stereotypes of new varieties. In 1987 the first quarter of this ratio, sowing on March 18, April 19 single inserted, June 13 full heading, mature July 11, the whole growth period of 115 days, than the “Golden Early 6” precocious 6 days. In 1988, the model of 4.25 mu was sown on March 16 and planted on April 24. Beginning of June 10 Sui, 14 full heading. The heading date is 5 days earlier than “78130” and 1 day later than “Red 410”. In 1987 alone, the plot production was measured at a yield of 334.06 kg per mu, which was 3.82% less than that of “Jinzao 6”. The variance analysis was not significant. Plant height of 89 cm, plant leaf state is good, strong tillering, light blight, late ripe color green branches. Single copy effective acres of ear 196,000, 103 grains per ear. Seed set rate of 96.0%, 1000 grain weight
