Abstract:
Twenty six Trachyspermum ammi gentoypes were evaluated in Rabi 2020 at Chilli and Vegetabile Research Unit (CVRU), Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (MS) for estimates of genetic diversity and correlation coefficients for thirteen morphological traits by laying down the field experiment in randomized block design with three replications. The observations were recorded for thirteen important yield and yield contributing traits. Genotypes, PDKV AJ 11 and PDKV AJ 10 found high potential for seed yield, whereas PDKV AJ 14, PDKV AJ 19 and PDKV AJ 02 were the early maturing genotypes. Based on the D2 estimates these twenty-six genotypes were grouped into four clusters, cluster III comprised maximum number of genotypes (nine) followed by cluster I and cluster IV which comprised six genotypes while cluster II included only five genotypes. Analysis of variance indicated significant differences among the genotypes for all the traits under study. The phenotypic coefficient of variation (PCV) was higher than genotypic coefficient of variation (GCV). High heritability was observed for test weight followed by number of umbels per plant, seed yield per plant, days to first flowering, number of seeds per umbel, number of umbellate per umbel and days to 50 per cent flowering. The high genetic advance was observed for number of seeds per umbel, number of umbels per plant, days to first flowering and plant height at maturity. Seed yield per plant was significant and positively correlated with days to first flowering, days to 50 per cent flowering, number of primary branches per plant, number of seeds per umbel, number of umbels and test weight.
