选用含Tm 2 nv基因的早熟红果材料与早粉 2号杂交 ,其后代经分离选择育成早熟粉果自交系 92 0 354,从国内杂种一代材料中分离、鉴定、选择育成优良粉果自交系 92 0 387,以二者为亲本组配成番茄一代杂种陇番 8号 ,果实为扁圆形 ,粉红色 ,平均单果质量 138.7g ,熟性极早 ,自开花至采收仅需 4 5d(天 ) ,较西粉 3号早熟 9～ 10d(天 ) ,前期产量 6 6 7m2 16 78.4 6kg ,占总产量的38.2 6 % ,较对照高 18.3% ,在北京、石家庄、郑州、兰州、乌鲁木齐和合肥等地表现良好 Selection of early-matured red fruit material containing Tm 2 nv gene crosses with early powder No. 2, and its progenies are bred from the inbred line 92 0 354 of early-ripening maize by isolation and identification. Department of 92 0 387, the two as the parent group with tomato hybrid generation Long Fan 8, the fruit is oblate, pink, the average fruit mass 138.7g, very early maturity, since flowering to harvest only 4 5d (days), 9 ~ 10d (days) earlier than Xi powder 3, 6 6 7m2 16 78.4 6kg, accounting for 38.26% of the total output, 18.3% higher than that of the control. In Beijing, Shijiazhuang, Zhengzhou, Lanzhou, Urumqi and Hefei and other places performed well
