Adapatation Evaluation of Different Cultivars of Chenopodium quinoa in Southwest Zhejiang

In April 2020, interplanting of 8 cultivars of Chenopodium quinoa was implemented in young Camellia olefera stand in Qingyuan county, Zhejiang province. Observation and determination was carried out on their agronomic traits, lodging resistance and production traits. The results showed that 8 cultivars could grow normally in Qingyuan, with growth period of 106-125 days. Correlation analysis on 15 traits showed that seed yield had significantly positive relation with single plant yield, height and the height of the first effective branch (P<0.05), but extremely significant negative relation with lodging rate (P<0.01). The cumulative contribution rate of 3 principal components from 15 characters by principal component analysis was 86.62%. Comprehensive evaluation of principal components demonstrated ‘Hongli’ had the highest score and the best adaptability and followed by ‘Jili No. 1’. 8 cultivars could be divided into 4 groups at genetic distance of 5.
