A new pepper variety called Zunjiao 4 was created by selecting the best traits from an existing variety. It has high nutrition, gives a lot of peppers, and can resist diseases well. Zunjiao 4 grows well in Zunyi and similar places, with each plant producing about 290 kilograms of peppers in 185 days. The peppers are colorful, tasty, and have a good shape. This new variety is now being grown in different parts of Guizhou province.
