“脱毒紫花白”是乌盟农科所与中国农科院作物所合作,于1975年从茎尖脱毒苗中筛选出来的抗病、高产株系,经扩大繁殖在生产上推广后,深受农民的欢迎。因其为紫花白肉,所以叫“紫花白”。该品种幼苗粗壮,色泽深绿,生长较快,株高40—50厘米,株型直立,分枝3—4个,顶小叶片呈阔卵形,侧小叶呈长卵形,叶片肥大而排列疏密适中。出苗后一个月左右就完成了植株生长阶段;一般个体叶面积值达3.5—3.8平方米,形成强大的光合作用体系,并进入 “Virus-free Purple White” is the cooperation between UNAMIDO and the Chinese Academy of Agricultural Sciences Crops, in 1975 screened from stem-tip virus-free seedlings of disease-resistant, high-yielding strains, after expanded production in the promotion of production, Popular by farmers. Because of its purple white meat, so called “purple white.” The varieties of seedlings sturdy, dark green color, grow faster, height 40-50 cm, plant type erect, branches 3-4, the top small leaf was broadly ovoid, side lobular was long oval, leaf hypertrophy and arranged Moderate density. The emergence of a month or so to complete the plant growth stage; general individual leaf area value of 3.5-3.8 square meters, forming a powerful system of photosynthesis, and enter
