我所驻井岗山大队蔬菜基点的同志与贫下中农一起于1969年开始进行番茄杂交组合的研究,选出了“北京早红”ד粤农2号”,“北京早红”ד满丝”,“北京早红”ד东州24号”三个杂交组合(以下简称北×粤、北×满、北×东),1970年多点试种结果,杂种番茄产量比当地栽培品种“北京早红”、“长箕大红”增产1～5倍,深曼群众欢迎。1972年试种面积扩大到412亩,杭州郊区种植30亩北×粤、北×满,平均亩产11000斤。其中3亩北×粤亩产高达14130斤。此外,据井岗山9队试验,杂种番茄较亲本增产26.5～66.7%,尤以北×粤、粤×北的绝对产量与增产百分比表现最高,北×满、北×东、东×北次之。
Comrades from the vegetable base of the Jinggangshan Brigade in my hometown started their research on tomato hybrid combinations with the poor peasants in late 1969 and selected “Beijing early red” × “Yue Nong 2” and “Beijing early red” × “full Silkworm ”,“ Beijing early red ”ד Dongzhou 24 ”hybrid combinations (hereinafter referred to as North × Guangdong, North × Man, North × East), 1970 multi-point test results, hybrid tomato yield than the local cultivars “Beijing early red”, “long-Kei red” an increase of 1 to 5 times, deep Man welcome. 1972 planted area expanded to 412 acres, 30 acres of northern suburbs of Hangzhou planted × North Guangdong, North × full, the average yield 11000 pounds. Among them, 3 mu North × Guangdong mu produce up to 14,130 pounds. In addition, according to Jinggang 9 team test hybrid tomato yield 26.5 ~ 66.7% more than the parent, especially in North × Guangdong, Guangdong × North absolute yield and yield percentage of the highest performance, North × full, North × East, East × North times It
