甘蔗新品种福农41号的选育与评价

Evaluation and Breeding of a New Sugarcane Cultivar Funong41

福农41号是从组合ROC20×粤糖91-976经多年选育出的中熟高产高糖强宿根甘蔗新品种,并于2014年通过国家鉴定。多年多点试验结果表明:福农41号出苗较好,苗壮,分蘖力较强,植株较高,中大茎至大茎,易脱叶,57号毛群不发达;抗黑穗病,中抗花叶病,宿根性好,耐寒性和宿根性比ROC22强,群体结构的自我调节能力强,主茎与分蘖茎差异小,生长整齐,适宜机械化生产。多年多点试验结果表明,福农41号平均蔗茎产量、含糖量和甘蔗蔗糖分都比对照ROC16和ROC22高。

New sugarcane variety Funong 41 was selected from the cross ROC20×YT91-976. It was a new sugarcane cultivar released by Ministry of Agriculture in 2014 with high yield, high sucrose content, good ratooning ability and wide adaptability. The results from different sites for several years showed that it had many good characteristics, such as good germination, strong tillering, mid-high plant, mid-big stalk, easy to trash, few hair group, resistance to smut, mid resistance to mosaic, strong resistance to adversity. Its low-temperature resistance and ratooning ability was better than ROC22. It has the high ability for group self-adjustment. The difference between main stem and tiller stem is little, and suitable for mechanized production. The results from different sites for several years showed that the cane yield, sucrose content and sugar yield of Funong41 all higher than that of the checks ROC16 and ROC22.
