番茄是一种很受欢迎的果菜,是茄科番茄属半蔓性草本植物。从野生种到栽培种一般都是总状花序、合轴分枝、果穗分层、一序多花由大至小顺序排列。野生种每序花数很多,果实很小,栽培种则每序花数较少,而果实较大。1975年7月初,我们在大寨公社大寨大队、武家坪大队的早粉二号中发现六株每序均为单花的番茄,它在田中表现叶系稀疏,果大早熟。对这种类型的番茄我们进行了单株单果留种。经过连续三代观察、选育及多地试种,发现单花性状稳定,可以做为我国一个番茄资源材料。
Tomato is a very popular fruit and vegetable, a tomato family of tomato plants. From wild to cultivated species are generally raceme, co-axial branches, ear stratification, in order from a large number of flowers arranged in descending order. Wild species in each order a lot of flowers, the fruit is very small, cultivated species per flower less, while the larger fruit. At the beginning of July 1975, we found in the early powder No.2 of Dazhai Brigade and Wujiaping Brigade in Dazhai commune of six tomato plants, each of which is a single flower in sequence, showing sparse leaf clusters and large fruit trees in Tianzhong. For this type of tomato, we planted single fruits. After three consecutive generations of observation, breeding and multi-field trials, we found that single flower traits are stable and can be used as a tomato resource material in China.
