随着我国粮食生产发展和人们生活水平提高,马铃薯的用途逐渐向商品型转化,尤其自“七五”以来,马铃薯加工业的兴起与发展,对高淀粉适于加工、出口创汇品种的要求日益迫切.为了适应生产和市场发展的需要,我所于1978年开展了抗病、高产、优质新品种选育研究,于1991年育成了克新12号.1 选育经过克新12号是用Dorita自交种子选育而成.1979年培育实生苗,当年从实生苗群体中入选一批优良单株无性系,1980年参加选种试验,原编号为克7943—7,1981年参加品系预备试验,1982~1987年参加品系比较试验,1988年参加区域预备试验
With the development of grain production in our country and the improvement of people’s living standards, the use of potatoes has been gradually transformed into commercial products. Especially since the “Seventh Five-Year Plan” period, the potato processing industry has been on the rise and development. Urgent.In order to meet the needs of production and market development, I carried out in 1978 in disease resistance, high yield, high quality new varieties of breeding research, in 1991 bred new grams 12 .1 Breeding through the new No. 12 is Dorita self-bred seed breeding .1979 nurturing seedlings, the year selected from the seedling population of a group of excellent clones, in 1980 to participate in the selection test, the original number is grams 7943-7, in 1981 to participate in the preparation of strains Test, from 1982 to 1987 to participate in the comparative test of strains, in 1988 to participate in the regional preliminary test
