【摘要】 采用随机区组排列设计,对毕节地区农科所选育的5个马铃薯新品种(系)进行了比较试验,以期选出适宜高寒山区的品种。结果:B9901-56、B9901-51和B9904-17高产、抗病,综合表现好,可在毕节威宁山区推广应用。B9901-56产量居参试品种第一位(2 900.0 kg/667m2),大薯率、单株结薯数均较高,但淀粉含量较低(10.827%);B9901-51产量居第二位(2 275.0 kg/667m2),淀粉含量一般(14.647%);B9904-17产量较高(2 225.0 kg/667m2),淀粉含量居第一位(16.423%),可作为毕节地区自育的一个高淀粉型品种进行推广。更多还原

【Abstract】 Five new potato varieties bred from Bijie Agricultural Institute are tested by the random block design to select potato varieties adapting to mountainous areas with high elevation. The results show that B9901-56, B9904-51 and B9904-17 with high yield, resistant to diseases and better comprehensive characters can be popularized in weining mountainous areas. The yield of B9901-56 with lower starch content （10.827%） is the highest (2900.0kg/667m²) among the tested varieties. The yield of B9904-17 with the highest starch content （16.423%） is the third highest （2225.0kg/667m²） among the tested varieties which should be popularized in Bijie prefecture.更多还原
