Diversity analysis in ajwain (Trachyspermum ammi L.)

Abstract

Agronomy instruction farm, Sardarkrushinagar Dantiwada Agricultural University, Dantiwada, evaluated diversity studies for forty genotypes of ajwain during rabi 2019–20 using a randomised block design (RBD) with three replications. Nine clusters were formed from the genetic divergence of the forty genotypes studied for seed yield. With twenty-one genotypes, cluster I had the most. This was followed by cluster III, which had nine, cluster VII, which had four, and clusters II, IV, V, VI, VII, VIII, and IX, which each had one genotype. The 40 genotypes under investigation showed signs of diversity. Clusters VII and III had the greatest intercluster distance (D2=897.53), which was followed by clusters V and III (D2=768.35). The traits, including seed yield per plant, test weight, biological yield per plant, harvest index, number of branches per plant, volatile oil, number of umbels per plant, and days to flowering, had the greatest impact on the selection of parents with different genetic backgrounds.
