随着科学技术的不断进步,我国的科研单位利用脱毒技术,将普通品种大蒜胚芽切取0.3～0.5毫米的分生组织,在适宜的培养基上进行离体培养,诱导再生形成幼苗,经过病毒检测确定无病后,再在防早网或空间隔离条件下扩大繁殖,培育成脱毒大蒜新品种。一、特征特性:脱毒大蒜其瓣较大,蒜皮呈淡红色、双层、蒜秸较硬,单株蒜苔重30～40克,一般亩产蒜苔250～300公斤,单蒜头重100～160克,干燥后,亩产蒜头1500～2000公斤,比普通品种早熟4～7天,生长势强,高抗霜霉病、软腐病,耐肥,丰产性能好,生长期240天左右,一代良种可连续栽培3～4年,适宜在全国大多数地区栽
With the continuous improvement of science and technology, the scientific research units in our country use detoxification technology to cut the ordinary germ of garlic germ of 0.3-0.5 millimeter, cultivate in appropriate culture medium, induce regeneration to form seedlings, Detection of disease-free, and then in the prevention of early network or space-based conditions to expand breeding, breeding into new varieties of detoxification garlic. First, the characteristics and characteristics: a large flap of virus-free garlic, garlic skin was pink, double, garlic straw hard, single plant garlic moss weight 30 to 40 grams, general mu produce garlic 250 to 300 kg, 160 grams, after drying, per mu garlic 1500 ~ 2000 kg, 4 to 7 days earlier than ordinary varieties, strong growth potential, resistant to downy mildew, soft rot, fertilizer, high yield performance, growth period of about 240 days, Continuous cultivation of 3 to 4 years, suitable for planting in most parts of the country
