Evaluation and Breeding of A New Sugarcane Variety Funong 38

福农38号系从组合粤糖83-257×粤糖83-271中经多年选育出的中熟高产高糖强宿根适应性广甘蔗新品种,并于2013年通过国家鉴定。多年多点试验结果表明,福农38号出苗较好,苗壮,分蘖力强,植株高,中大茎,易脱叶,57号毛群不发达,高抗黑穗病,高抗花叶病,抗逆性强。平均蔗茎产量104.21t/hm2,分别比对照种新台糖22号、新台糖16号增产4.53%、10.76%。11—12月平均蔗糖分14.48%;1—3月平均蔗糖分15.53%;11—3平均蔗糖分15.08%,分别比对照新台糖22号、新台糖16号高0.24%、0.49%。平均蔗糖产量15.69t/hm2,分别比对照种新台糖22号、新台糖16号增糖6.16%、14.28%。

New sugarcane variety Funong 38 was selected from the cross of Yuetang83-257 x Yuetang83-271. It was as a new sugarcane variety with middle maturity, high yield, high sucrose content, good ratooning ability and wide adaptability in 2013. The results from different experimental sites for several years showed that it had such good characteristics as good germination, strong tillering, high plant, mid -big stock, easy to trash, few hair group, high resistant to smut and mosaic, and strong resistance to adversity. Its mean cane yield was 104.21 t/ha, increased by 4.53% and 10.76% in comparison with the control ROC22 and ROC16; The sucrose content of cane was 14.48%, 15.53% 15.08% during the period from November to December, from January to March and from November to March, respectively. The sucrose content from November to March increased by 0.24% and 0.49% in comparison with the control of ROC22 and ROC16. The sugar yield was 15.69 t/ha, increased by 6.16% and 14.28% in comparison with the control of ROC22 and ROC16.
