Genetic Variability Analysis of Yield and its Components in Niger [(Guizotia abyssinica (L. f.) Cass.]

Genetic Variability Studies for Yield and Its Attributing Traits in Niger (Guizotia abyssinica (L.f.) Cass)

“…Whereas low genotypic and phenotypic coefficients of variation were observed for the traits, such as days to 50% flowering (4.99% and 5.13%), days to flower initiation (4.49% and 4.76%) and days to maturity (2.64% and 2.78%). These results agree with the findings of, Gururaja et al [21] for days to 50% flowering, Bhoite et al [16] for days to maturity, Baghel et al [17], Suryanarayana et al (18), Bhoite et al [15] and Tiwari et al [22] for days to 50% flowering and days to maturity. High heritability was observed for all the traits viz., days to 50% flowering (94.74%), number of capitula per plant (93.02%), plant height (93.02%), number of secondary branches per plant (91.80%), number of seeds per capitula (91.10%), days to maturity (90.02%), seed yield per plant (89.18%), days to flower initiation (88.63%), 1000-seed weight (88.17%) and number of primary branches per plant (85.00%).…”

“…High genotypic and phenotypic coefficients of variation were observed for the traits, such as seed yield per plant (44.44% and 47.06%) followed by number of capitula per plant (27.99% and 28.88%) and number of seeds per capitula (26.53% and 27.80%). These results are in conformity with the findings of Amsalu (10) for seed yield per plant, Bhoite et al [15] for number of branches per plant, number of capitula per plant and number of seeds per capitula, Bhoite et al [16] for number of capitula per plant and number of seeds per capitula, Baghel et al [17] for seed yield per plant and number of capitula, Suryanarayana et al [18] for number of capitula per plant, Kumar and Bisen [14] for seed yield per plant and number of capitula per plant, Ahmad et al [19] for number of capitula per plant and Pradhan et al [20] for number of seeds per capitula.…”

These results are in accordance with Gururaja et al [21] for the trait plant height (cm), primary branches, secondary branches, days to 50% flowering and seed yield per plant (g), Amsalu [10] for seed yield per plant, Baghel et al [17] for trait days to maturity, days to 50% flowering, plant height (cm), capitula per plant, seed yield per plant (g), seeds per capitula and primary branches per plant, Kumar and Bisen [14] for all the traits except number of branches per plant, Tiwari et al [22] for days to maturity, days to 50% flowering, seed yield and plant height.…”

“…Moderate genotypic and phenotypic coefficients of variation were observed for the traits, such as number of secondary branches per plant (18.08% and 18.87%) followed by plant height (15.79% and 16.37%) and 1000-seed weight (12.81% and 13.64%). Similar findings have been reported by Bhoite et al [15,16] for plant height, Gururaja et al [21] for 1000-seed weight, Suryanarayana et al [18] for plant height and number of branches per plant and Baghel et al [17] and Tiwari et al [22] for plant height.…”

Evaluation of Genetic Variability for Quantitative and Qualitative Characters in Niger [Guizotia abyssinica (L.f) Cass] Local Germplasm

“…Mean sum of square High genotypic coefficient and phenotypic coefficient of variation was recorded for number of secondary branches per plant followed by number of capitula per plant, 1000 seed weight, seed yield per plant, number of seed per capitula, number of primary branches per plant, days to 50% flowering showing greater scope for selection for improvement of these characters. Similar results were reported by Borole and Patil (1997), Sreedhar (2003), Patil and Duhoon (2005), Thakur and Reddy (2012), Kumar and Bisen (2016), Kusumlata et al, (2018).…”
