多年来由于辣椒品种混杂退化,抗逆性差、病害重,严重影响产量。虽然近些年来采取了药剂防治、改进栽培技术等综合防治措施,使产量有所提高,但选育抗病丰产、品质优良的品种,仍是非常迫切的任务。 1978年在小区品比试验中,从美国引入的品种比拉尔选出了一个优良株系22—1,通过系统选育,稳定成新品种定名为辽椒一号。通过品种对比、区域试验和生产示范,证明辽椒 Over the years as a result of hybrid varieties of pepper degradation, poor resistance, heavy disease, seriously affecting the yield. Although comprehensive prevention and control measures such as chemical control and improved cultivation techniques have been taken in recent years to increase production, breeding of high-yielding and high-quality varieties is still a very urgent task. In 1978 in the plot ratio test, Balaer introduced from the United States selected an excellent strain 22-1, through the system breeding, stable into a new variety named Liaogao. Through variety comparison, regional trials and production demonstration to prove pepper
