Exploring Variation, Selection Criteria and Genetic Diversity in Wheat

The book delves into an extensive research study carried out at the Wheat Research Station, Junagadh Agricultural University, during Rabi 2018-19, focusing on the genetic dynamics of bread wheat (Triticum aestivum L.). The experiment, employing a randomized block design with two replications, thoroughly explores genetic variability, correlation coefficients, path coefficient analysis, selection indices, and genetic divergence, centering on key agronomic traits. Notable findings include significant genetic variations among wheat genotypes, with traits like grain weight per main spike, biological yield, and 1000-grain weight displaying substantial levels of both genotypic and phenotypic coefficient of variation. The study identifies promising genotypes, such as JAU-2018-17, JAU-2018-18, and JAU-2018-19, for superior grain yield and yield-contributing characteristics. Correlation and path coefficient analyses underscore the pivotal role of biological yield and 1000-grain weight in directly influencing grain yield. The book also emphasizes the efficiency of selection indices based on biological yield and harvest index.
