| In recent years, Luosi pepper cultivation has developed rapidly in the Hanzhong region, but problems such as mixed varieties, poor adaptability, a high summer fallow rate, and low economic benefits remain. To screen superior Luosi pepper varieties suitable for long-season greenhouse cultivation over summer in the Hanzhong region, the comprehensive indicators of three introduced Luosi pepper varieties were measured, and principal component analysis was used for adaptability evaluation. The results showed that all three varieties were suitable for long-season greenhouse cultivation over summer. Among them, ‘Yuyi Damahua’ and ‘Luojiao 43’ had the highest yields, while ‘Shanjiao 2018’ had the highest economic benefit, with significant differences from the other treatments. Principal component analysis showed that ‘Shanjiao 2018’ ranked first in comprehensive evaluation score, followed by ‘Luojiao 43’, which did not differ significantly from ‘Yuyi Damahua’. These results provide a reference for Luosi pepper variety selection and diversified market layout. |
