我区从1991年秋开始试制秦油2号杂交种。三年来,制种基地都选择在秦岭以南、汉水以北的长江中上游地区,海拔在430～800米之间。三年总的制种亩产虽然不足50公斤,但每年都有一些高典型。如1993年亩产在70公斤以上的制种户和面积分别占当年制种总户数和面积的19.8%和20.9%;亩产80公斤

My district from the autumn of 1991 trial No. Qin hybrid 2 hybrid. In the past three years, all seed production bases have chosen to be located in the middle and upper reaches of the Yangtze River to the south of the Qinling Mountains and north of the Hanshui River at an elevation of 430 to 800 meters. Although the total seed production per mu in three years is less than 50 kg, there are some high typicals each year. For example, in 1993, the number of seed-producing households with an area of ​​more than 70 kilograms per mu and the area occupying 19.8% and 20.9% of the total number and area of ​​seed-producing areas in that year respectively; and the yield of 80 kilograms per mu
