Screening of New High-Quality,Disease-Resistant,Chopping-Dedicated Pepper Hybrids Suitable for Cultivation in Rucheng
摘要
Abstract
Rucheng County in Hunan Province is a major production area for chopping-dedicated peppers in China.Some of the currently dominant pepper varieties exhibit poor adaptability to the local climatic conditions—low temperatures and rainy weather in spring,high temperatures and drought in summer—and fail to meet processing requirements.To screen high-quality,disease-resistant,chopping-dedicated pepper varieties suitable for Rucheng,this study analyzed the variability,correlation,and principal components of 13 major agronomic traits in 49 new pepper hybrids.The results showed that the coefficients of variation for the 13 agronomic traits ranged from 12.56%to 49.57%,and Pearson correlation coefficients varied from 0.01 to 0.87.Through principal component analysis(PCA),five principal components—plant height,plant spread,main stem length,main stem diameter,and leaf length—were identified as evaluation indicators for agronomic traits,with a cumulative variance explanation rate of 75.81%.The 49 hybrids were further evaluated based on PCA results,fruit quality,and maturity.Two new hybrids,19GZ06 and 17MD11,exhibited moderate fruit size,easy fruit stalk abscission,yields exceeding 2,700 kg per 667 m²,dry matter content above 18%,pungency greater than 30,000 SHU,and strong resistance to anthracnose,phytophthora blight,and viral diseases.These two hybrids are suitable as dedicated varieties for pepper chopping processing.关键词
