Evaluation of Different Genotypes of Ridge Gourd for Better Growth, Yield and Quality under Prayagraj Agro-Climatic Conditions

Abstract

Ridge gourd, scientifically known as Luffa acutangula, is a tropical vine that belongs to the Cucurbitaceae family. It is commonly grown for its young and tender fruits, which are used as a vegetable in cooking. It is known by various names, including Kalitori, angled gourd, angled loofah, silky gourd, and ribbed gourd. Ridge gourd has a chromosome number of 2n = 26. This versatile vegetable can be incorporated into a wide range of dishes, such as stir-fries, curries, soups, and stews, thanks to its mild and slightly sweet flavor. In the Kharif season of 2022. a study was conducted at the Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology and Sciences in Prayagraj, Uttar Pradesh, to assess the performance of different ridge gourd genotypes under the local agro-climatic conditions. The experiment followed a Randomized Block Design and involved nine genotypes with three replications each. The genotypes included G1 (IET 2021/RIGHYB-1), G2 (IET 2021/RIGHYB-2), G3 (IET 2021/RIGHYB-3), G4 (IET 2021/RIGHYB-4), G5 (IET 2021/RIGHYB-5), G6 (IET 2021/RIGHYB-6), G7 (IET 2021/RIGHYB-7), G8 (Dharidar-8), and G9 (Jaipuri Long-9).Based on the results of the experiment, it was determined that the genotype IET 2021/RIGHYB-5 exhibited the best performance in terms of growth parameters, such as vine length (222.10 cm) and early maturity, with the first fruit ready for picking in 60.00 days. It also excelled in yield parameters, including fruit length (25.03 cm), fruit diameter (5.65 cm), and fruit yield per plant (1528.31 g/plant). Additionally, IET 2021/RIGHYB-7 demonstrated outstanding performance in quality parameters, including Total Soluble Solids (TSS) at 4.23°Brix and Vitamin C content at 2.05 mg/100g.
