Wilczek Nitesh M Jagdhane, Suresh BG, B Jalandhar Ram and Priyanka Yadav Abstract Twenty mungbean (Vigna radiata L. Wilczek) genotypes were evaluated for the estimation of genetic variability parameters, Heritability and Genetic advance. The genotypes differed significantly for all characters. Higher GCV and PCV was observed for cluster per plant (31.33%;32.51%) followed by number of primary branches per plant (30.58%;32.95%), number of pods per plant (20.07%; 24.07%), plant height (12.10%; 12.74%), harvest index (11.89%;13.09), seed yield per plant (10.16%; 11.49%), seed per pod (8.33%; 12.44%) High heritability coupled with high expected genetic advance was observed in biological yield (99.00%; 7.59%) indicating the impact of additive gene expression. Keywords: Greengram, Genetic variability, Heritability, Genetic advance Introduction Mungbean [Vigna radiata (L.) Wilczek] is a short duration legume crop belongs to the order Leguminosae and Papilionoideae family. It is a self-pollinating diploid legume with the chromosome number 2n=2x=22 (Karpechenko, 1925) [7] . Mungbean probably originated in India (De Candole, 1886) [3] or the Indo-Burmese region (Vavilov, 1951) [13] . The primary gene center of diversity for mungbean was suggested to be the central Asian region (Vavilov, 1951) [13] with India as the gene center and probable center of domestication (Smartt, 1985) [15] . In India greengram is cultivated in area of 3.38 million hectares with an average productivity of 4.74 qt / ha and production of 1.61 million tonnes, (IIPR Annual Report 2015-2016). In Uttar Pradesh greengram is cultivated area of 0.72 lakh hectares with an average productivity of 5.5 qt/ ha and production of 0.40 lakh tonnes, (IIPR Annual Report 2015-2016). Mungbean is a major source of protein and minerals for the predominantly vegetarian population of India. Hundred grams of mungbean seeds composed of carbohydrates (62.62 g), sugars (6.60g), dietary fibre (16.3g), vitamin-C (4.8 mg), magnesium (189 mg), phosphorous (367 mg), potassium (1246 mg) and sodium (15 mg). Average protein content in the seeds is around 23% (USDA Nutrient Database). Mungbean is ranks third among pulses after chickpea and pigeon pea in area and production. Mung bean contributes 18.07% of total pulses area and 11.48% of total pulses production in India. Area, production and productivity of mung bean in India is 34.4 lakh ha, 14 lakh tonnes and 406.98 kg/ha respectively. In Uttar Pradesh, it is being cultivated in an area of 0.72 lakh hectare with 0.40 lakh tonnes production and productivity is 555.56 kg/ha (Anonymous, 2012) [1] . Mungbean is predominantly a self-pollinated crop. It is an annual herbaceous, erect or semi- erect, with slight tendency for twining in the upper branches, leaves are trifoliate with basal appendages, stipules minute and leaflets entire ovate. Inflorescence is axillary or terminal raceme with 10-20 flowers crowned on long peduncle, flowers are either light yellowish, olive or live yellow, hermaphrodite, zygomorphic, 5 sepals, 5 petals, 10 stamens in diadelphous (9 +1) condition, single carpelled ovary with hairy style. Immature pods are green and mature pods have iron-grey or live grey or snuff brown color, 4 to 16 cm long, rounded, slender spreading or relaxed with short and moderate pubescence dehices by both (ventral and dorsal) satures into two halves contain 9-16 seeds with yellowish cotyledons.

Correlation coefficient analysis is a handy technique, which elaborates the degree and extent of relationship among important plant characters and it provides basic criteria for selection and leads to directional model based on yield and its components in the field experiments.Keeping in view 20 mungbean genotype received from the department to assess genetic variability and correlation Materials and Methods The present investigation was carried out at the Field Experimentation Centre, Department of Genetics and Plant Breeding, SHUATS, Allahabad (U.P.) during Kharif-2016.
