Growth and Yield Comparisons among Sweet Pepper Cultivars in South Korea

This study was carried out to select sweet pepper varieties suitable for summer cropping among 12 varieties(red and yellow 6 varieties, respectively) cultivated in South Korea. We investigated their characteristics of growth and yield in Cheorwon, Gangwondo from March to October in 2012.

The plant heights of tested varieties appeared to be 270~307cm, and stem diameter appeared to be 15.7~18.8mm. The stem appeared to have nodes of 34~37 per plant. The averaged fruit weights of several varieties were more than 300g, expecially "Nagano" showed the highest, 312g. On the other side, "Dandan" showed the lowest, 221g.

In Red-type Paprika, the ranges of pericarp thickness and soluble solid content revealed 6.0~7.3mm and 8.3~9.0°Brix. The storage life in M.A. packaging was evaluated to be 20 to 30 days. The contents of Vitamin C showed 130~213mg/100g. Of 6 varieties, "Davos" and "Nagano" showed the highest yields, 10.4 and 10.6 kg/m², respectively.

In yellow-type Paprika, the ranges of pericarp thickness and soluble solid content revealed 6.3~7.1mm and 7.7~8.4°Brix. The storage life in M.A. packaging was evaluated to be 17 to 26 days. The contents of Vitamin C showed 139~216mg/100g. Of 6 varieties, "Yorit" and "Yellow mountain" showed the highest yields, 10.0 and 10.6 kg/m², respectively.

On the base of yield, we selected "Davos" and "Nagano" of red-type varieties, and "Jorrit" and "Yellow mountain" in yellow-type varieties as suitable varieties for summer cropping in Gangwondo, South Korea.
