Assessment of variability, heritability and genetic advance in brinjal under Terai region of Uttarakhand

Abstract

An experiment was conducted at the Vegetable Research Centre, G. B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand during the Kharif season 2023 to determine the relationship between the characteristics affecting the plant growth and yield parameters in brinjal. The experiment was conducted in Randomize Block Design with twelve genotypes of brinjal. Highly significant differences were observed among forty-three diverse brinjal genotypes for various traits. Fruit yield per plant showed the highest phenotypic and genotypic coefficient variation. The lowest values ​​were recorded for days to first fruit picking. Low differences were observed between GCV and PCV values ​​across all traits. The heritability was estimates high (above 71.50%) for all traits. High genetic relatedness, indicating that they are controlled by additive genes and can be effectively improved through selection.
