Correlation and Heritability Analysis for Seed Quality under Controlled Conditions in Wheat (Triticum aestivum L.)

Abstract

A study was conducted on wheat (Triticum aestivum L.) in laboratory at Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya, Uttar Pradesh, during the 2019–20 for correlation and heritability analysis for seed quality under controlled conditions in wheat. In a wheat crop research, 30 germplasm were tested using three checks each for the parameters of seed weight, seed width, seed length, shoot length, root length, seedling length, seedling dry weight, germination (%), first count, final count, and vigour index-I and vigour index-II. In this study, the germplasm was assessed using parameters and the correlation coefficient. The vigour index-II demonstrated a very significant positive phenotypic connection with root length (0.828), final count (0.564), and first count (0.552), as well as a genotypically significant positive correlation with final count (1.165), root length (0.867), and first count (0.552). The high estimates (>15%) of phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) were registered in the case of vigour index-I (PCV=17.36%, GCV=17.24%), shoot length (PCV=15.96%, GCV= 15.77%), seed width (PCV= 15.35%, GCV= 15.19%). The moderate estimate (10%) of PCV and GCV were recorded for root length (PCV=12.72%, GCV=12.56%), and seedling length (PCV= 11.46, GCV= 11.30).
