Abstract
This experiment was carried out in a shade net house at the horticultural research farm of Agriculture and Forestry University, Chitwan, Nepal during spring 2018to identify the suitable radish (Raphanus sativus L.) variety having high yield potential with better quality roots for off season. The experiment was laid out in Randomized Complete Block Design (RCBD) with eight treatments, i.e. five improved (Vedetar Local, Miyasinge, Tokinasi, Pusa Chetki and All Season) and three hybrid varieties (Mino Early Long White F1, Ivory White F1 and MAHY 22 F1) of radish with four replications.Radish seeds were seeded in the third week of February. Miyasingevariety showed the highest plant height (43.91 cm), biomass yield (73.22t ha-1) and fresh shoot weight per plant (127.15 g)whereasthehighest number of leaves per plant (20.54) was recordedinMAHY 22 F1. Ivory White F1 variety showed thehighest root length (19.51cm), root circumference (9.31cm), root to shoot ratio per plant (1.29) and fresh root yield (30.87 t ha-1). The highest root skin thickness (0.27 cm) was found in Miyasinge,the highest TSS (6.20 ºBrix) was observed in Mino Early Long White F1. Ivory White F1 showed the highest ascorbic acid content (19.51 mg 100 g-1),dry matter of root (7.62 %) and score (8.36) from the consumers’ acceptability test for pungency. Ivory White F1 showed superior growth, yield and quality attributesunder shed net conditions.
