摘要
甜玉米新品种金甜5868是以自育系T31为母本、T32为父本经选育而成的鲜食玉米单交种。2014—2016年参加甘肃省鲜食甜玉米区域试验,3 a 15点(次)鲜穗平均折合产量为13437.5 kg/hm2,较对照减产2.47%。2017年参加甘肃省鲜食甜玉米生产试验,鲜穗平均折合产量为14680.0 kg/hm2,较对照品种超甜603增产0.52%。从出苗到采收需≥10℃活动积温1900℃左右,在甘肃平均采收期92 d。籽粒可溶性糖含量为67~94 g/kg,还原糖含量为6.0~6.6 g/kg,总糖含量≥100 g/kg。高感禾谷镰孢穗腐病、丝黑穗病,中抗瘤黑粉病,抗倒折倒伏性好。适宜在甘肃鲜食甜玉米种植区和与该种植区条件相同的北方鲜食甜玉米种植区域种植。
Jintian 5868,a new sweet corn cultivar,is a single breed,was bred with T31 as female parent and T32 as male parent.In 2014—2016,the average yield of fresh ear in 3 a 15 sites(times)was 13437.5 kg/hm2 and 2.47%lower than that of the check in Gansu Sweet Corn Regional Trial.In 2017,the average yield of fresh ear was 14680.0 kg/hm2 and 0.52%higher than that of the check Chaotian 603 in Gansu Sweet Corn Production Trial.From seedling emergence to harvest,the≥10℃activity accumulated temperature about 1900℃,and the average harvest period in Gansu was 92 days.The soluble sugar content of grain was 67~94 g/kg,reducing sugar content was 6.0~6.6 g/kg,total sugar content was≥100 g/kg.It is highly susceptible to Fusarium graminearum ear rot,head smut,medium resistance to Oncomelania,and good resistance to lodging.It is suitable to be grown in the planting area of Gansu Province and the northern fresh sweet corn planting area with the same conditions in North China as the planting area.
