Selection parameters associated with essential oil yield comprise genetic and chemical diversity and the morphological expression of photosynthetic efficient agronomical traits in Vetiver (Chrysopogon zizanioides Roberty)

RK Lal, CS Chanoutiya, SS Dhawan, A Mishra and P Gupta

Using Mahalanobis D2-statistics and eleven of the most economically important features, the nature and extent of genetic divergence in eighty vetiver genotypes were evaluated. The vetiver underwent Mahalanobis D2 analysis, which found a significant level of variety. Nine clusters were formed from the genotypes. Cluster I had the most genotypes (56), followed by cluster II (6), III (5), IV (3), V (3), VI (2), VII (2), VIII (2), and IX (2), with one in cluster IX. Cluster III genotypes had the highest average divergence ( =52.51), followed by cluster IV ( =49.59) and cluster VII ( =45.46). Cluster III and VII (D2=85.52), Cluster IV and Cluster VII (D2=81.04), and Cluster IV and IX (D2=73.11) had the highest inter-cluster distances, implying that the genotypes found in these clusters could be utilized for future breeding programmes. The significant contributors to genetic divergence were α-vetivone, essential oil yield, photosynthetic rate/net CO2 assimilation rate, and transpiration rate, respectively. These varieties, such as Nos. 70, 25, 60, 15, 6, and 3 can be used to create commercial vetiver varieties.
