Abstract
Genetic Variability, Heritability and Correlation Study of Physiological and Yield Traits in Relation to Heat Tolerance in Wheat (Triticum aestivum L.)
Highlights
Wheat (Triticum aestivum L.), a cereal grass of Graminae (Poaceae) family and of the genus Triticum, is the world’s largest cereal crop
Observations were recorded on grain yield and its related traits, viz., days to heading, days to anthesis, days to maturity, grains per spike, 1000-grain weight
Twenty genotypes were undertaken for assessment of direct selection parameters, variation was higher than their respective genotypic coefficient of variation for all the traits [17,18,19,20,21,22]
Summary
Wheat (Triticum aestivum L.), a cereal grass of Graminae (Poaceae) family and of the genus Triticum, is the world’s largest cereal crop. Genetic Variability, Heritability and Correlation Study of Physiological and Yield Traits in Relation to Heat Tolerance in Wheat (Triticum aestivum L.). The association between the traits related to heat tolerance could be better understood through correlation study both at genotypic and phenotypic levels [8]. The characters like 1000 grain weight and plot yield exhibited higher values of phenotypic variance while other traits showed similar trend. This suggests that there is a good scope of selection for these factors [14,15,16].
