1978年秋,用汕优2号与威20杂交,经连续四代选择高结实率优良株系,育成了新品种78130。此品种主茎15叶,早季全生育期125～130天,倒种春115天;株态近似汕优2号,但剑叶短直;每亩有效穗20～25万,每穗60～80粒,结实率稳定90％以上,千粒重27～28克,亩产400～450公斤,高产可上500公斤;耐寒又耐淹,抽穗扬花期对风雨适应性好;高抗稻瘟病,兼抗白叶枯病和稻曲病;后期根叶不早衰,谷粒饱满;适应性广;米质中上。1983～1985三年累计全省推广约260万亩。若每亩以最低增产量25公斤计算,全省可增粮6500万公斤以上;包括粮食增产,种子加价和节省防病工本,其社会效益可达2000万元。经福建省农作物品种审定委员会审定,列为全省推广早稻良种之一。1986年早季,全省种植面积可达250万亩以上。
The autumn of 1978, with the Shanyou 2 and Viagra 20 cross, after four generations of high-selection rate of fine lines, breeding a new variety 78130. This variety main stem 15 leaves, the early growing period of 125 to 130 days, 115 kinds of inverted spring; stalks approximate Shanyou 2, but the short leaves straight; per acre effective spike 20 to 25 million per spike 60 ~ 80 grains, the seed setting rate is stable over 90%, the grain weight is 27-28 g, the yield is 400-450 kg, the yield is high 500 kg, the resistance to cold and flood, the adaptability to wind and rain at heading and flowering stage, Bacterial leaf blight and rice false smut; late root failure is not premature, full grain; wide adaptability; From 1983 to 1985, the total province has promoted about 2.6 million mu for three years. If the minimum output per acre 25 kilograms, the province can increase grain 65 million kilograms or more; including grain production, seed fare increase and save disease prevention, the social benefits of up to 20000000 yuan. Approved by the Fujian Provincial Crop Variety Approval Committee, listed as one of the province to promote early rice varieties. In the early morning of 1986, the province’s planted area of up to 2.5 million mu.
