甘蔗长期是用种茎进行繁殖,繁殖系数低,用种量大(一般每亩用种1吨左右)。一个新品种的选育,推广费时太多,一般要10多年,影响了新老品种更替和良种经济效益的发挥。由于以原料茎作种,降低了原料茎的利用率。甘蔗组培苗产量和糖分接近或等于种茎苗,后代生产性能与亲本一致且分蘖多,生长快,宿根性好,繁殖系数高。现将
Sugarcane long-term use of stems for breeding, breeding coefficient is low, with a large amount of seed (usually about 1 ton per mu for planting). Breeding of a new breed, promotion time-consuming too much, generally more than 10 years, affecting the replacement of new and old varieties and the economic benefits of seed play. As the raw material stems for planting, reducing the utilization of raw material stems. The yield and the sugar of the tissue culture seedlings of sugarcane are close to or equal to the seedlings of the seedlings. The progenies have the same production performance as the parents and more tillers, faster growth, better rooting and higher propagation coefficient. Now
