当前,全国各地大多利用“克疫”品种所结的天然种子生产实生薯,这个品种的实生薯具有抗病、增产的特点,但熟性、株型、花色和薯形等性状还有较大的分离,给生产和消费带来一定的困难。我们在马铃薯自交系选育和马铃薯新品种选育过程中,发现一些单系天然种子的实生薯在性状分离、抗病性等方面都显著优于“克疫”实生薯,例如我们从“乌盟601×岷县15号”育种材料中一个单株的自交二代选
At present, most of the country uses the natural seeds produced by the “K” epidemic species to produce real potatoes. The real potatoes of this variety have characteristics of resistance to disease and increased yield, but there are still many characteristics such as maturity, plant type, flower color and potato shape The separation, to bring some difficulties in production and consumption. In the process of selection of potato inbred lines and breeding of new varieties of potato, we found that some of the single-seed native seeds of real potatoes were significantly better than “gram-negative” in terms of trait separation and disease resistance. For example, Wuxian 601 × Minxian 15 "breeding materials in a single self-made second-generation selection
