贵州4个辣椒新品种的性状表现

为筛选适合贵州省多地种植的优良辣椒新品种,以遵辣6号为对照(CK),选择辣椒新品种遵辣ZLAB-1×ZLR-1、遵辣ZLAB-2×ZLR-2、ZXJ1306、黔椒11号分别于2014年和2015年在贵州省多个试点进行辣椒品种区域试验,测定4个参试新品种的产量,观察其植物学性状、抗病性、品质等表现。结果表明:各参试品种均能较好地适应各试点环境,顺利完成生育期,与CK相比,各参试新品种早熟性明显,分枝力强,生长势旺,采收期长。其中,遵辣ZLAB-1×ZLR-1丰产性、稳定性好,平均干椒产量为4 861.05kg/hm~2,与CK相比增产20.39%,抗病性最强,综合性状优良,且遗传多样性也最丰富。黔椒11号产量稳定性最佳,平均干椒产量为4 302.60kg/hm~2,比CK增产6.65%。遵辣ZLAB-1×ZLR-1更适合在贵州省多地大面积推广应用,黔椒11号可作为辣椒产业发展的后备品种。

Performance of Characteristics of Four New Pepper Varieties in Guizhou

To screen fine pepper varieties suitable for planting in Guizhou,regional tests were conducted in many test sites in Guizhou to explore the yield,botanical characters,disease resistance and quality of the following varieties,Zunla 6(CK),ZLAB-1 ZLR-1,ZLAB-2 ZLR-2,ZXJ1306 and Qianjiao 11.Results:All the pepper varieties fitted various environments well in Guizhou and completed the growth period smoothly.Compared with CK,all the new pepper varieties were of apparent prematurity,strong branching ability,vigorous growth vigor and long collection time.ZLAB-1 ZLR-1 was of good yielding ability and stability,the strongest disease resistance,excellent comprehensive traits and the most abundant genetic diversity.And the mean yield was 4 861.05 kg/hm2,20.39％ higher than CK.Qianjiao 11 had the best yield stability,the mean yield was 4 302.60 kg/hm2,6.65％ higher than CK.ZLAB-1 ZLR-1 is more suitable for popularization and application in many places of Guizhou,and Qianjiao 11 can be seen as the reserved variety in pepper industry development.
