摘　　要：“正月红”是从“南香”柑芽变中选育的宽皮橘晚熟新品种,其植物学特征表现为树姿开张,树势中等,枝梢短硬无刺;果实综合性状优良,中等大,扁圆形,肉质柔软多汁,化渣性好,高糖,品质优;果皮较厚、火红色、易剥离,果面光滑,耐贮藏。“正月红”定植3 a开始结果,5 a进入盛果期,产量达37500 kg/hm^(2)。果实留树保鲜贮存至翌年开花而不浮皮,糖度更高,风味更浓,正值翌年水果淡季2—5月上市销售,经济效益高。该品种抗病性和抗寒性强,适宜在鄂西-湘西柑橘带海拔400 m以下的柑橘产区秋季或春季栽植。该文主要介绍了“正月红”柑橘新品种的选育过程、主要特征特性、产量表现及经济效益和栽培技术要点。’Zhengyuehong’is a late-maturing Citrus reticulata variety newly selected from the bud-mutated’Nankou’hyrid citrus.Its botanical characteristics feature the opening tree type,medium tree vigour,and short and hard branches without thorns.Its fruits,covered with smooth,thick and flame-red peel easy to remove,are medium size in oblate form,having excellent comprehensive characteristics,soft and juicy pulp,good mastication,high sugar content,and excellent quality,which are storage-resistant.’Zhengyuehong’will begin fruiting 3 years after planting,and enter the full fruit period in the 5th year with an output of 37500 kg/hm^(2).If kept growing on the tree until the next year’s blossom period,the fruits are still puffing-resistant with higher sugar degree and stronger flavor;at that time,they are just right on sale in the off-season(February-May)of next year,thus making great profits.The variety has strong disease resistance and cold resistance,which is suitable for planting in citrus producing areas(elevation≤400 m)of Western Hubei to Western Hunan in spring or autumn.This paper introduces the breeding process,main characteristics,yield performance,economic benefits and key cultivation techniques of’Zhengyuehong’.
