马铃薯是我省晋北和其它山区的一种主要粮食作物。目前存在的问题是,各地采用的栽培品种,大都严重混杂、退化,或不抗晚疫病,致使马铃薯产量不高不稳。因此,生产上迫切需要提供丰产、质优、抗晚疫病、抗毒病或耐毒病以及具有其它优良性状的新品种,以代替严重混杂、退化了的老品种。一、育种工作中存在的问题我所担负着全省马铃薯的育种任务,自1950—1962十多年来,先后曾引进国内外优良品种300余个,培育杂交后代数以千计。
Potato is a major food crop in northern Shanxi and other mountainous areas in our province. The current problem is that most of the cultivated cultivars used in various places are mostly mixed, degraded or not resistant to late blight, resulting in low and unstable potato yield. Therefore, there is an urgent need in production to provide new varieties with high yield, good quality, resistance to late blight, anti-poison or poison resistance and other excellent traits, so as to replace the seriously mixed and degraded old ones. I. Problems in Breeding Work I have undertaken the task of breeding potatoes throughout the province. Since the 1950s-1950s, more than 300 domestic and foreign fine varieties have been introduced and thousands of hybrid descendants have been cultivated.
