Variability and character association studies in garden pea (Pisum sativum var. hortenseL.) during winter season at mid hills of Himachal Pradesh

Abstract

Fifty four genotypes including four checks were grown in a RBD with three replications during Rabi 2010-11 at Vegetable Experimental Research Farm, Nauni, Solan HP to estimate the parameters of variability and association of important characters with yield in garden pea. Analysis of variance showed significant differences among the genotypes for all the morphological characters under study. The genotypic and phenotypic coefficients of variation were high for total soluble solids, total sugars, pod yield per hectare and total phenols. High heritability estimates coupled with high to moderate genetic gain observed for pod yield (kg/plot), node at which the first flower appear (number), number of pods per plant and total Phenols (g/100g). Pod yield was positively correlated with number of pods per plant, pod length (cm), number of seeds per pod and shelling percentage thereby indicating that the selection based on these traits could be effective for improvement of green shelled peas yield.

Study on Genetic Variability, Heritability and Genetic Advance in Garden Pea (Pisum sativum var. hortense L.)

“…Similar findings were also reported by Afreen et al, (2017), Katoch et al, (2016), Jaiswal et al, (2015), Kumar et al, (2015), Ahmad et al, (2014), Asfakun et al, (2013), Kumar et al, (2013) and Pal and Singh (2013). The moderate amount of GCV were recorded for Days to 50% flowering (18.55%), Days to pod setting (18.12%), fibre content (13.33%), pod width (13.28%), number of seeds per pod (12.90%), pod length (12.08%), days to first pod picking (12.06%), number of pods per cluster(9.50%), shelling per cent(9.30%) and seed yield per plant (8.36%).…”

“…The estimates of heritability (%) in broad sense for 20 characters studied, which range from 53.36% to 99.23% hence, high heritability (broad sense) was recorded for all the characters. Similar results were noticed by Afreen et al, (2017), Georgieva et al, (2016), Jaiswal et al, (2015); Kumar et al, (2015); Ahmad et al, (2014); Siddika et al, (2013);Habtamu and Million (2013); Kumar et al, (2015); Pal and Singh (2013); Fikreselassie, (2012); Guleria et al, (2009);Sharma et al, (2003) and Kumarai et al, (2008).…”

Estimation of the Different Parameters of Variation through Biometrical Approach in Pea (Pisum sativum L.)

“…Out of ten characters nine characters observed for high heritability viz., yield per plant (94.78%), days to maturity (92.58%), plant height (85.69%), 100-seed weight (84.75%), pod density (83.25%), pod length (80.61%), pods per plant (77.63%), seeds per pod (76.64%), and days to 75% flowering (66.51%). Similar results were noticed by Afreen et al, (2017), Georgieva et al, (2016), Jaiswal et al, (2015); Kumar et al, (2015); Ahmad et al, (2014); Habtamu and Million (2013); Kumar et al, (2015); and Kumarai et al, (2008). Low heritability was recorded for primary branches per plant (37.68%).…”

Diversity analysis of pea genotypes using RAPD markers

“…and thus these areas are thought to be rich in primitive cultivated forms of field pea (Kapila et al 2011). The consumers also have a special preference for pea from hilly regions due to its characteristic flavor, good quality and sweetness (Kumar et al, 2015). Molecular markers can overcome the difficulty over morphological markers in analyzing genetic divergence of increasing number of reference germplasm collections.…”
