第二轮国家甘蔗品种区域试验湛江点试验结果

经过广东湛江旱坡地2年新植1年宿根试验，试验结果表明：参试的11个新品系中，粤糖91－976、云蔗89－7、桂糖91－116、闽糖92－649、福农91－21、桂糖90－95、粤糖89－240等7品系均比对照品种新台糖10号、粤糖63－237增产增糖；闽糖90－55、福农91－23比两对照品种增产，比粤糖63－237增糖、但糖分不及新台糖10号；川蔗19、川蔗91－91公顷含糖量、蔗产量均居参试品系的最后两位。在各品系的平均蔗糖分中，桂糖91－116居第一位，高于两对照；川蔗91－91、粤糖89－240、桂糖90－95及粤糖91－976低于新台糖10号、高于粤糖63－237；其余6品系均低于两对照。

Analysis of the Second Round Regional Test of National Sugarcane Varieties in Zhanjiang

After two years of regional test on plant cane and one year regional test on ratoon cane in upland in west Guangdong, the experiment showed that the average cane yield and average sugar yield of YT 91-976, YZ 89-7, GT 91-116, MT 92-649, FN 91-21, GT 90-95 and YT 89-240 were higher than that of ROC10 (check variety in China) and YT 63-237 (check varieties in Guangdong Province). The average cane yield of MT 90-55, FN 91-23 were higher than that of the two check varieties, the average sugar yield of these two varieties were higher than that of YT 63-237, low than that of ROC10. The average cane yield and average sugar yield of CZ 19, CZ 91-91 ranked the last two in all eleven tested varieties. The average sugar content of all eleven tested varieties, GT 91-116 was the highest, ranked first, higher than that of the two check varieties. CZ 91-91, YT 89-240, GT 90-95 and YT91-976 were higher than that of YT 63-237, low than that of ROC10, the other six varieties were low than that of the two check varieties.
