牡丹江地区马铃薯新品系品比试验

Comparative Experiment of New Potato Lines in Mudanjiang Region

为筛选适宜牡丹江地区种植的马铃薯高产优质品种,2021年在黑龙江省牡丹江市温春镇以‘克新13号’为对照,对黑龙江省农业科学院牡丹江分院自育的8个马铃薯新品系进行品比试验。结果表明,马铃薯新品系‘M019-6’产量最高(68495 kg/hm^(2)),‘M019-8’产量次之(63537 kg/hm^(2)),‘M016-2’再次(62577 kg/hm^(2)),分别较‘克新13号’(CK)增产13.94%、5.70%和4.10%,且和对照相比差异均达到显著水平;食味评分分别为6、5、6分。综合评价,这3个新品系综合性状优良,商品薯率较高,产量高,品质好,薯形好,整齐度较好,抗病性强,可作为黑龙江省牡丹江地区的优良马铃薯中晚熟及晚熟品种继续试验。

The experiment was carried out in 2021 in Wenchun Town,Mudanjiang City,Heilongjiang Province,on eight new potato lines bred by Mudanjiang Branch of Heilongjiang Academy of Agricultural Sciences,using’Kexin 13’as a control,in order to screen out potato varieties with high yield and high quality suitable for planting in Mudanjiang region.The new potato line’M019-6’had the highest yield(68495 kg/ha),followed by’M019-8’(63537 kg/ha)and’M016-2’(62577 kg/ha).Compared with’Kexin 13’(CK),the yield was increased by 13.94%,5.70%and 4.10%,respectively,and the differences were significant.The score of taste for these three lines was 6,5 and 6,respectively.According to the comprehensive evaluation,these three lines have good comprehensive characters,high marketable tuber percentage,high yield,good quality,good tuber shape,good uniformity and strong disease resistance,and could be used as potential mid-late maturity and late maturing potato varieties for further testing in Mudanjiang region of Heilongjiang Province.
