Comparison of Postharvest Quality of Snack Slim 502 and PC3 (A9) for Promoting New Careers for
Farmers in the Marginal Highland Area; Ban Bor Meung Noi, Nahaew District, Loei Province

Tomato cvs. Snack Slim 502 ( SS) and PC3 ( A9) were developed and bred by the National Center for 
Genetic Engineering and Biotechnology and a private sector in order to support new career for the special small community of marginal highland area Bor Meung Noi, Nahaew District, Loei Province. The objective of this study is to compare the postharvest quality of 2 cultivars of small tomato fruits for new commercial produced. The tomatoes were grown during November 2020 y February 2021. Fresh fruits were harvested and transported to Postharvest Technology laboratory, KMUTT Bankhuntien, Bangkok. Comparison of a difference between means of independent samples with 4 replications by statistic test (t-test). The both tomato fruits are cylindrical shape, but the tip of SS fruit is pointed shape whereas PC3 fruit is rounded shape. The color of both tomato cultivars were expressed as values of tomato fruit, L*, a*, b*, chroma and hue angle showed no significant differences in both fruit. However, the SS fruits is significantly higher TSS. /TA ratio and pH than PC3 variety difference. However, titratable acidity and firmness were not significantly different (p< 0.05). It was concluded that the two varieties of tomatoes did not differences in some physical and chemical properties can encourage farmers to grow for 
commercial purposes.
