摘要
品种单一、青枯病危害严重是制约广东省冬作区马铃薯产业发展的重要因素,为筛选出适宜广东省冬作区种植的高产、抗青枯病的马铃薯新品种,引进16个马铃薯新品种(系),以‘费乌瑞它’为对照,于2019~2020年冬季进行田间比较试验。结果表明,所有参试品种中,‘华薯12号’对青枯病表现为高抗,产量为40290 kg/hm2(居第2位),较对照增产48.29%;‘华薯13号’和‘华薯10号’对青枯病表现为抗病,产量分别为40328和38667 kg/hm2(分别居第1位和第3位),较对照分别增产48.43%和42.31%;‘华彩3号’和‘华薯1号’对青枯病表现为中抗,产量分别为35901和33212 kg/hm2(分别居第4位和第5位),较对照分别增产32.13%和22.24%。这5个品种长势好,产量高,综合性状表现突出,适宜广东冬作区推广种植。
Few varieties available for choice and the serious damage of bacterial wilt are the important factors that restrict the development of potato industry in winter cropping area of Guangdong Province.To screen new potato varieties with high yield and resistance to bacterial wilt suitable for winter planting in Guangdong Province,16 new potato varieties(lines)were introduced to conduct the screening test of new potato varieties,using the variety'Favorita'as a control,in the winter of 2019-2020.Among all the tested varieties,'Huashu 12'showed high resistance to bacterial wilt,and its yield was 40290 kg/ha(ranking the second),which increased by 48.29%compared with the control.'Huashu 13'and'Huashu 10'were resistant to bacterial wilt,and their yields were respectively 40328 and 38667 kg/ha(ranking the first and the third,respectively),which increased by 48.43%and 42.31%,respectively,compared with the control.The yields of'Huacai 3'and'Huashu 1',mid resistant to bacterial wilt,were 35901 and 33212 kg/ha(ranking the fourth and the fifth,respectively),which increased by 32.13%and 22.24%,respectively,compared with the control.The five varieties have good growth,high yield and outstanding comprehensive characters,which are suitable for planting in winter cultivation area of Guangdong Province.
