Abstract:

This study uses 25 mini pumpkin introduced varieties (lines) as experimental materials to conduct a comprehensive analysis and evaluation of 17 main traits, aiming to screen out mini pumpkin varieties (lines) with good comprehensive quality, and provide scientific reference for promoting the high-quality development and variety promotion of characteristic pumpkin industry in Kaizhou District, Chongqing. The results showed that there were significant differences in various traits among the 25 mini pumpkin varieties (lines). The top five varieties ranked in the comprehensive scores of principal component analysis were ‘WF3’, ‘WF15’, ‘WF9’, ‘WF14’ and ‘WF10’. These varieties have balanced and outstanding performance in yield, flavor and quality, and are suitable for promotion and cultivation in Kaizhou District. In addition, three types of excellent varieties with specific traits have been identified, including high-yield type (‘WF10’ and ‘WF14’), high-sugar type (‘LuKang 901’) and high-starch type (‘WeiJia’), which can meet the needs of processing and functional consumption.
