Web(2011) reported high PCV and GCV values for number of capsule per plant and seed yield per ha. Similarly, Gidey et al. (2012) found high PCV and GCV values for seed yield per ha. Siva et al. (2013) obtained high GCV values for number of capsule per plant. Heritability and genetic advance: A heritability estimate for characters under study is ... Webpopulations showed significant GCV and PCV values for productive tillers per plant, grains per panicle, grain yield per plant and straw yield per plant, indicating that these traits may be ...

Phenotypic Coefficient of Variation (PCV) was somewhat higher than the respective Genotypic Coefficient of Variation (GCV) for all the character reflecting that the environment had little effect on the characters. GCV was found higher for the Number
Webvariation (PCV) for all the traits studied were higher than the genotypic coefficient of variation (GCV). Highest PCV and GCV was recorded for single plant yield with a value of 40.16 % and 33.21 % respectively, while lowest PCV (6.82 %) and GCV (4.50 %) was observed for spikelet fertility. Estimates of PCV and GCV for all the traits were WebA. GCV And PCV are classified as suggested by Sivasubramonium & Madhavarmenon in 1973 as < 10% Low 10-20% Moderate > 30% High Interpretation of Coefficient of variance If, GCV> PCV, it means little influence of environment on the expression of character. Selection for improvement of such character would be rewarding.

Similar results were also reported [8] The GCV and PCV were moderate for number of seeds … driving hypoglycaemiaWebThe difference between GCV and PCV gives us an idea about role of genotypic and environment on the character (Bhujbal et al., 2013) [5]. Narrow differences were observed between PCV and GCV for days to corm sprouting, plant height, leaf length, leaf width, stem girth, days to 50 per cent flowering, duration of driving impressions catfish kit car
