目前兰州栽培的辣椒品种以大、小羊角为主,因品种单一,病害严重,致使栽培面积逐年减少,严重影响市场供应和菜农的收入。据报道,国外在生产上已普遍采用杂种一代,国内自70年代起发展亦很迅速,如湘研辣椒系列组合等已应用于生产。我省目前生产上还无辣椒杂交种。针对上述现状,我们开展了辣椒一代优势利用研究。一、杂种优势的表现青椒一代杂种优势极强,据报道高优组合比当地品种增产30％～50％,有的高达
At present, the varieties of cultivated peppers in Lanzhou are dominated by large and small horns. Due to the single breed and serious disease, the cultivated area has been reduced year by year, seriously affecting the market supply and income of vegetable growers.
