“…This showed that although there was a strong genetic correlation between the two variables, the impact of environmental factors on phenotypic expression reduced it. For ajwain seed yield and yield components, Singh et al (2019) [14] , Subramaniyam et al (2018) [16] , Meena et al (2016) [9] , Chauhan et al (2019) [4] , Sandhu et al (2018) [13] , Nagappa et al (2017) [10] , and Sravanthi et al (2014) [15] have all seen that estimations of genotypic correlations frequently exceed the corresponding phenotypic correlations (Table . 2). Days to maturity, plant height, number of umbels per plant, number of umbelletes per umbel, biological yield per plant, harvest index, and test weight were determined to be the most significant yield attributing factors and to have a substantial and favourable impact directly on seed yield per plant.…”

At the Sardar Krushinagar Dantiwada Agricultural University's Agronomy Instructional Farm in Dantiwada during the rabi 2019-20, forty ajwain genotypes were assessed. On the mean sum of squares, each attribute has a significant effect. The GCV and PCV were modest for the number of branches plant -1 , umbels plant -1 , umbelletes umbel -1 , seeds umbel -1 , seeds plant -1 , biological yield plant -1 , test weight, and volatile oil. The number of branches plant -1 , the number of umbels plant -1 , the number of umbelletes umbel -1 , the number of seeds umbel -1 , the number of seeds per plant -1 , the test weight, and the volatile oil all showed high heritabilities when combined with GAM. Plant height, number of branches, umbels, umbelletes, number of seeds, biological yield plant -1 , harvest index, test weight, and volatile oil are all significantly and positively connected with seed yield plant -1 . The path analysis identified favourable direct impacts on seed yield per plant for days to maturity, plant height, number of umbels, number of umbelletes per umbel, biological yield per plant, harvest index, and test weight.
