桂糖72/287(CP49/50×F134)是生势好、宿根性好、有效茎多、高产的中小茎品种。缺点是迟热、低糖。针对这些缺点,我们于1980年以其蔗芽进行辐射诱变处理。经过八年的筛选、品比和区域试验,从诱变苗群体中,选育出一个较好的新品种“桂辐80/29”。该品种经同工酶分析,证明是个突变新品种,其产量、宿根性保留原种优势,表现为早熟、高糖。早期(10—12月)新、宿平均蔗糖分13.58%,比原供体(桂
Gui sugar 72/287 (CP49 / 50 × F134) is a good growing potential, good rooting, effective stalk, high yield of small stems varieties. The disadvantage is that after the heat, low sugar. In response to these shortcomings, we mutated their sugarcane shoots in 1980. After eight years of screening, product ratio and regional trials, a better new variety “Gui Hui 80/29” was bred from mutants and mutants. The isozyme analysis of the variety, proved to be a new mutant, its yield, rooting retain the advantages of the original species, manifested as precocious, high-sugar. In the early stage (October-December), the average daily intake of sucrose was 13.58%, lower than that of the original donor (Gui
