VRPLK-2: A superior genotype of spinach beet for round the year cultivation

Abstract

The aim of present study on spinach beet was to evaluate the performance of best performing genotypes during round the year monthly sowing for two consecutive years in the climes of northern Indian plains at ICAR-Indian Institute of Vegetable Research, Varanasi, Uttar Pradesh. The marketable biomass yield for VRPLK-2 was realized 136-887 q/ha during round the year sowing which is 56-147% higher than check variety All Green because of faster plant growth, 16-33 days delayed-bolting habit and 1-2 more number of cutting(s). Overall, the biomass yield of spinach beet was harvested maximum during August to November sowing (Autumn & Winter season crop) followed by December to February sowing (Spring season crop) and minimum during March to July sowing (Summer & Rainy season crop). Higher biomass yield potential, delayed-bolting habit, faster plant growth, more number of cutting, longer cropping period and wider adaptability to different growing conditions & seasons for genotype VRPLK-2 make it a unique genotype whose genetic potential could be utilized in breeding programmes to widen the genetic variability towards delayed bolting habit and to increase the genotypic adaptability in varied climates in spinach beet.
