Abstract: The present study was conducted to determine the GCV and PCV, Hertiability and Genetic Advance for the yield contributing characters of Rose varieties. Eleven field rose varieties (Arka parimala, Arka pride, Arka savi, Arka sinchana, Arka swadesh, Seven days rose, Scent pink, Mirabel red, Roman red, Roman yellow and Mookuthi yellow) were selected for this study. Amongst all fourteen parameters studied, High PCV and GCV was recorded for the parameter number of flowers per sprout, number of petals per flower, number of flowers per plant, number of leaves per shoot, plant spread E-W. High heritability was observed in the parameters viz. Number of flowers per sprout, Number of petals per flower, Plant spread E-W, Petal length, Shelf life, Number of leaves per shoot, Number of flower per plant, Fresh weight of flower, Fully opened flower diameter, Plant height, Number of shoots per plant, Plant spread N-S, Flower stalk length, Days taken for flower bud initiation. High GAM was observed in the parameters viz. number of flowers per sprout, number of petals per flower, number of flowers per plant, number of leaves per shoot, plant spread E-W, flower stalk length, shelf life, petal length, plant spread N-S, fresh weight of flower, fully opened flower diameter, plant height, number of shoots per plant, days taken for flower bud initiation. For the analysed parameters the varieties, Mirabel red, Seven days rose, Scent pink, Arka parimala was recorded as the superior among all the eleven varieties.
