甘蔗新品种粤引618的引进与选育

Introduction and Breeding of the Sugarcane Variety Yueyin 618

粤引618系广州甘蔗糖业研究所2006年从巴西引进的甘蔗新品系,经5年种性试验选育而成的高产高糖甘蔗新品种。该品种高糖、丰产稳产、中至中小茎、萌芽快齐、分蘖力强、宿根性较强、抗逆性较强,农艺性状佳。多年多点试验结果表明,粤引618公顷产蔗115.87 t,分别比对照种ROC16和ROC22增产60.9%和16.2%;产糖16.54 t/hm2,分别比ROC16和ROC22增糖57.5%和19.0%;粤引618甘蔗蔗糖分含量在11月～次年1月平均达15.51%,分别比ROC16和ROC22提高0.53个百分点和0.26个百分点。粤引618主要农艺性状、蔗茎产量、含糖量、蔗糖分、抗逆性均优于ROC16和ROC22,适合在粤、桂、滇等蔗区繁殖试种。

Abstract： Yueyin 618 was introduced from Brazil in 2006 and bred for five years by Guangzhou Sugarcane Industry Research Institute. Yueyin618 was an excellent new sugarcane variety with desirable characteristics of high cane and sugar yields, stable yield, medium to medium small stalk, strong perennial and ratooning ability, strong resistance and good agronomic characters. The results of plant tests conducted at different sites for several years showed that the average cane yield of Yueyin 618 was 115.87 t/hm2, increased by 60.9% and 16.2% compared with ROC16 and ROC22. The sugar yield of Yueyin 618 was 16.54 t/hm2, increased by 57.5% and 19.0% compared with ROC16 and ROC22. Sucrose content of Yueyin 618 was 15.54% from November to January, 0.53% and 0.26% higher than that of ROC16 and ROC22. The agronomic characters, cane yield, sugar yield, sucrose content of Yueyin 618 were significantly superior to the cheek varieties ROC 16 and ROC22 and it can be planted on a trial basis in sugarcane areas, such as in provinces of Guangdong, Guangxi and Yunnan.
