Hybrid Improvement of Chinese Radish

บทคัดย่อ

Nine inbred lines of Chinese radish were investigated for their self-incompatibility levels using fluorescent microscope technique and seed set analysis. The results showed that most of the inbred lines were self-incompatible. They were crossed in all combinations to be selected for the best hybrid variety. From varietal trial and ability to set seeds, it was found that hybrid 27 x 18 and some of hybrid 77 x 18 had good horticultural characteristics such as uniformity, dark green leaf without hair, cylindrical shape, smooth skin, firm texture of root and root weight of about 360-400 g. These characteristics are market acceptable. Root yield of these hybrids in the previous experiments was a lot higher than marketed varieties. The hybrid varieties should be further tested in farmer’s field.
