用马铃薯的实生籽繁殖种薯,主要有以下好处: 一、增加产量:马铃薯实生籽繁殖的当代,实生薯无性繁殖系的1—3代,可比当地主栽品种增产30％以上,尤以第一、二代增产效果明显。 二、抗病、抗退化:病害一般是通过块茎循环感染的,实生籽不带病原,所以实生薯的后代很少发生病害。实生籽除带纺锤块茎病毒外,不带其他病毒,故实生籽的后代,基本上无退化现象。 三、抗旱、抗寒、适应性强:在特殊干旱和高温情况下,当地主栽品种,枯死株经常发
Reproductive seed potato with potato seed, the main benefits are as follows: First, to increase production: potato seed reproduction of contemporary, real potato clonal 1-3 generations, more than the local varieties of cultivars yield more than 30%, especially in the First, the second generation effect is obvious. Second, disease resistance, anti-degradation: disease is usually infected by the tuberous loop, real seed without the pathogen, so the offspring of real potato rarely occur disease. Except for spindle seedlings tuberous virus, without other viruses, so the seeds of progeny, basically no degeneration. Third, drought, cold, strong adaptability: In the case of special drought and high temperature, the local cultivars, dead plants often hair
