Thick stem of the potato, in the Man-type, leaf green, kidney-type, petiole, stem are green, veins, geranyl Department of purple, purple-red skin potato, spindle type, the high rate of potato, sweet potato spring block 2-4 summer potato blocks 3-8, blockenlarged, smooth non-cleaved ditch resistance, storage, germination strong resistancelean, cooked noodles and sweet chestnut like incense and rich nutrition, high resistance to stem nematode, anti - root rot, is suitable for processing of starch, dry and cut the best varieties for human consumption.

该薯茎蔓粗壮，中蔓型，叶绿色，肾型，叶柄，茎蔓均为绿色，叶脉、叶基部紫色，薯表皮紫红色，纺缍型，大薯率高，春薯2-4块，夏薯3-8块，薯块膨大块，光滑无裂沟，耐贮藏，萌芽性强，耐肥耐瘠，熟食面甜而香似板栗，营养丰富，高抗茎线虫病、中抗根腐病，是适合加工淀粉、切干和食用最理想的品种。

There were close relation and harmonies among the quantities characters that were significantly hereditarily correlated with tumorous stem yield. High yield breeding combining with strong ecological adaptability and good quality should be largely based on later maturity, tumorous stem diameter, whole plant weight and higher ratio of stem and leaf.

瘤茎产量与营养生长期、瘤茎膨大期、瘤茎横径、茎/叶、株鲜重呈极显著遗传正相关，与菜形指数、菜皮百分率呈极显著遗传负相关，与其余性状相关均未达显著水平；与瘤茎产量显著相关的性状间关系密切，有很好的协同性，分析提出茎瘤芥育种选择熟性晚、瘤茎横径大、茎/叶高和植株个体较大的品种，可实现品种产量高、生态适应性强和瘤茎品质较佳等三者的协调统一。

Absence of the infundibular stem, abnormal thickening of the stem, and mass lesions involving the infundibular stem were the predominant abnormalities.

Firstly, we performed pulpotomy for posterior teeth and pulpectomy for anterior teeth. And the experiments were divided into four groups. In the first group, nothing was put in the pulp chamber or canals. In the second group, deciduous dental pulp stem cells of mini-pig with cultured medium were transplanted into the pulp chamber and pulp canals. In the third group, deciduous dental pulp stem cells of mini-pig with lovastatin were transplanted. In the fourth group, deciduous dental pulp stem cells of mini-pig with odontoblast induction medium were transplanted.

在动物实验中，我们将迷你猪乳牙的前牙作拔髓，后牙做断髓处理，各分成四组做实验，第一组不放任何细胞、第二组加入迷你猪乳牙牙髓干细胞和培养液、第三组加入迷你猪乳牙牙髓干细胞和lovastatin，第四组加入迷你猪乳牙牙髓干细胞和odontoblast induction medium，观察三个月后，以探讨其牙齿组织是否会再生。
