Abstract:

In order to screen out high-yield and excellent comprehensive traits of taste tomato, this study took 15 taste tomato varieties as research objects, yield-related indexes and agronomic traits were measured, and taste tomato varieties were comprehensively analyzed through a combination of principal component analysis and affiliation function analysis. The results showed that six varieties had a fruit setting rate higher than 80.0%. The average single fruit weight of 15 varieties was 89.3-181.2 g, plant height was 163.2-201.9 cm, stem thickness was 11.5-15.7 mm. The coefficient of variation of 12 agronomic traits ranged from 6.18% to 56.85%, the principal component analysis abstracted five principal components, and the variance contribution rate accrued to 82.477%, which could represent the agronomic traits of taste tomato to a large extent. This study selected three varieties with high yields, P121, KG1636, and 910, which have excellent comprehensive agronomic traits, multiple flowers per inflorescence, and high fruit setting rate.
