| dc.description.abstract | The present studies were carried out at Vegetable Research Centre (VRC) of the University, GBPUA&T, Pantnagar, Uttarakhand during kharif season of year 2020-21. Total of 38 turmeric genotypes were studied including 3 check varieties Pant Peetabh ,Sugandham and Narendra Haldi. The design of the experiment was laid out in Augmented Block Design . 38 genotypes were arranged in 7 blocks of 5 genotypes in each along with 3 check varieties. From each plot 5 plants were randomly selected and tagging was done for further observational recordings of growth yield parameters and morphological parameters. Data was compiled and it was fed to statistical analysis. Basic variability parameters like mean, range, and coefficient of variation and genetic variability parameters like PCV, GCV, heritability, genetic advance, correlation coefficient and path coefficient analysis were used for assessing the presence of variability in the experimental material. All characters were recorded PCV higher than GCV, but it is found that difference between the PCV and GCV was comparatively low for some characters suggesting characters mainly governed by genes and less affected by the environment. Heritability estimates of 9 characters ranged from 65.85% to 97.01%. Highest heritability was observed for Plant height (97.01%) and lowest for fresh rhizome yield (65.85%). Highest value of genetic advance was observed for fresh rhizome yield (146.89%) and Highest value of genetic gain was observed for number of mother rhizome (69.28%) and lowest for plant leaf lamina width (21.73%). Fresh rhizome yield showed a highly significant and positive correlation with number of leaves per plant (0.986), width of mother rhizome (0.491) and plant height (0.413). Non-significant and negative correlation was found with plant leaf lamina width and plant leaf lamina width. Number of leaves per plant (0.96573) has shown to exert highly positive direct effect on fresh rhizome yield. Characters such as plant leaf lamina length (-0.03592), plant height (-0.02249) and rhizome length (-0.02122) showed negative direct effect on fresh rhizome yield. The highest positive indirect effect on fresh rhizome yield was observed by width of mother rhizome (0.45736) which was followed by Plant height (0.38008), rhizome length (0.34555) and number of mother rhizome (0.25855) via number of leaves per plant. Based on the observations, it was concluded that in present study the important characters are plant height, number of leaves per plant, length of mother rhizome and width of mother rhizome. Genotype NYST-5 (654.16 q/ha) and NDH -35 (508.33 q/ha) found superior to check variety Pant Peetabh (452.77 q/ha), as they have superiority in these mentioned characters and such genotypes can be explored in breeding programme for further improvement of the turmeric crop. Genotypes such as NDH-129 (445.83 q/ha), Baga Haldi (441.66 q/ha) and Narendra Haldi-43 (379.16 q/ha) also showed high yield, which can be utilized in genetic improvement of rhizome yield in turmeric. | en_US |
