Abstract
The present study entitled “Genetic Studies in Spinach Beet (Beta vulgaris L. var bengalensis
Roxb.)” was conducted during rabi season of 2020-2021 at the Experimental Research Farm,
Department of Vegetable Science, College of Horticulture and Forestry, Neri, Hamirpur (HP). 15
genotypes of spinach beet including check “Pusa Harit” were evaluated in Randomized Complete
Block Design to assess the extent of genetic variability and work out heritability, genetic advance,
correlation, and path coefficient analysis with respect to different horticultural characters including
yield. The Analysis of variance for all the above quantitative traits suggested sufficient variability for
different quantitative traits; besides this variability was also found for the qualitative traits viz. leaf
shape and leaf color. The best genotype in terms of total yield per plant was P-COHF-NERI-11
(95.53g) which was however, statistically at par to the genotypes viz. P-COHF-NERI-4 (85.13g), PCOHF-NERI-3
(84.06g), P-COHF-NERI-1 (81.46g) and P-COHF-NERI-2 (80.20g). High GCV and
PCV values were expressed by the traits viz. fresh weight of leaves, dry weight of leaves and ascorbic
acid content. Highest heritability was shown by the trait ascorbic acid content. Whereas, highest
genetic advance as percentage of mean was seen for the trait dry weight of leaves. The highest
significant genotypic correlation was seen in the characters leaf length and leaf area on the total yield
per plant. Path analysis studies showed that the direct selection through the independent trait leaf area
could bring maximum improvement in total yield per plant.
