Evaluation of radish genotypes for microgreens production under red and laterite zone of West Bengal

Radish is widely highlighted root vegetable due to its availability, nutrient content and potential health benefits. However, the adaptability of radish microgreens has not been explored much. Based on this an experiment was conducted to assess the performance of fourteen radish varieties (Palak Patta, White Cone, Indian Radish China Queen, NBR-Indian Queen, Bahar 32, Kashi Hans, KashiArdra, Pusa Chetki Long, Improved Radish Rajni, Sundar Lal Aush, Chinese Pink, Local 1, Local 2 and Local 3) at microgreen stage for different morphological and physicochemical traits. Variation was observed among the genotypes for plant height, hypocotyl length, root length, fresh weight, yield and different phytochemical parameters. Radish cv. NBR-Indian Queen produced maximum microgreen yield (661.38 g/m²).Yield was positively correlated with plant height and hypocotyl length. Indian Radish China Queen recorded maximum amount of total phenol (145.67 mg GAE/100 g FW); whereas maximum ascorbic acid (202.587 mg/100 g FW) and beta carotene (19.98 μg of carotene/100 g FW) was in Pusa Chetki Long. The variation of morphological and nutrient composition among the different genotypes of radish offers the scope of selection of genotype. Radish cv. NBR-Indian Queen can be promoted to the growers for microgreen production.
