摘　　要：以20个新组合羊角椒品种为试材,在拱棚生长条件下,综合分析20个羊角辣椒品种的生育期、农艺性状、果实性状及产量,以期为新品种的审定、推广提供依据。结果表明：参试羊角椒品种物候期、植物学性状、抗病性、果实性状、产量及产值均有差异;参试羊角椒品种的开花、坐果期、始收期以0020、0023辣椒最早,较其余18个品种分别提前1～9、1～11、1～12d;0019辣椒株高最高、茎粗最粗,分别为130.4cm、2.12cm,较其余品种分别增加8.4～58.4cm、0.15～0.84cm,提高了6.9%～81.1%,7.6%～65.6%;单株结果数以0016辣椒最多,为25.4个,较其余品种增加1.2～9.4个,提高了5.0%～58.8%;0048辣椒结果数最少,仅为14.8个;0011、0012、0013、0016、0019、0020、0021辣椒品种抗病性强;参试的20个辣椒品种均为长羊角椒,味辣,皮薄,口感好;0014辣椒折合667m2产量、产值最高,分别为4 067.6kg、8 948.7元,较其余品种增产176.8～2 249.0kg,增收388.9～4 947.8元,产值增幅4.3%～55.3%。20new combinations of different pepper cultivars were used as materials,in the growth of archshed,the phenological period of hot pepper varieties,botanical characters,disease resistance,fruit yield and output value were comprehensively compared.The results showed that,there were different characters at the phenological period,botanical characters,disease resistance,fruit yield and output value in these varieties,compared with the other 18 varieties to advance 1to 9days,11 days,12days;the height of 0019 pepper was the highest with 130.4cm,stem diameter was the crude with 2.12 cm,compared with the other cultivars were increased 8.4-58.4cm,0.15-0.84 cm,improved the6.9%-81.1%,7.6%-65.6%;At fruit number per plant,the 0016 most chilies with 25.4,compared with the other cultivars increased 1.2-9.4,improved 5.0%-58.8%;the least number of 0048pepper;0011,0012,0013,0016,0019,0020,0021 peppers varieties of disease resistance;20pepper cultivars were long hot pepper,spicy,thin skin,good taste;667m2 yield and output value of 0014 pepper were the highest,with 4 067.6kg and 8 948.7yuan,compared with the other cultivars increased by 176.8-2 249.0kg,the income of 388.9-4 947.8yuan,increased in 4.3%-55.3%.
