粤糖04-252是广州甘蔗糖业研究所以粤糖94-128为母本、cp72-1210为父本通过有性杂交选育的优良甘蔗新品种,该品种早熟、中至中大茎、糖分高、丰产稳产;分蘖力强、宿根性好、抗病性能好、抗逆性较强,农艺性状佳。多年多点试验结果表明,粤糖04-252公顷产蔗95.160 t,比CK1、CK2和CK3分别增产20.9%、22.6%和1.5%,与CK1和CK2差异达极显著水平;产糖14.670 t/hm2,比CK1、CK2和CK3分别增产26.4%、25.2%和4.5%,差异均达极显著水平;粤糖04-252甘蔗蔗糖分含量在11月至次年1月平均达15.44%,比CK1、CK2和CK3分别提高0.67%、0.35%和0.43%,差异均达极显著水平。粤糖04-252主要农艺性状、蔗茎产量、含糖量、蔗糖分、抗逆性均优于对照种CK1、CK2和CK3,已在粤、桂、滇等主要蔗区繁殖试种。
Yue sugar 04-252 is the Guangzhou sugar cane sugar Institute of Yueshun 94-128 as the female parent, cp72-1210 as the male parent through sexual cross breeding of new varieties of good sugarcane, the variety of early maturing, medium to large stems, sugar High and stable yield; Strong tillering, good perennial resistance, good resistance, strong resistance, good agronomic characters. The results of multi-year trial showed that the yield of sugarcane from 04 to 252 hectares in Guangdong sugar was 95.160 t, which increased by 20.9%, 22.6% and 1.5% respectively compared with CK1, CK2 and CK3 and reached the extremely significant level with CK1 and CK2; hm2, which increased by 26.4%, 25.2% and 4.5% respectively than CK1, CK2 and CK3, the difference reached extremely significant level. The sucrose content of sugarcane from 2000 to 2000 was 15.44% , CK2 and CK3 increased by 0.67%, 0.35% and 0.43%, respectively, with significant differences among them. The main agronomic traits, cane yield, sugar content, sucrose content and stress resistance were all better than those of the CK1, CK2 and CK3, which had been cultivated in major sugar cane areas of Guangdong, Guangxi and Yunnan.
