abstract
The main bottleneck for the increase in area under mango cultivation is due to the non-availability of quality planting material of important cultivars at proper time in required amount. Wedge grafting has a tremendous potential which can be used for multiplication of Mango plants rapidly throughout the year either inside protected structers such as green house, Shade net house as well as in the open conditions. Looking to the scope and and importance of quality mango planting material a research was carried out at the Horticulture Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) during the year 2018-2019. The experiment consists of genotypes of mango i.e., Dashehari, Chhattisgarh Achar, Chhattisgarh Gourav, Chhattisgarh Pawan and Chhattisgarh Swarnaprabha, and 2 different environmental condition i.e. Net house and Poly tube caps. Thus, there were 10 treatment combinations and replicated four times under Factorial Complete Randomized Design (FCRD). The result concludes that among the genotypes the genotype G1 (Dashehari) was found significantly superior and exhibited maximum rootstock diameter (8.36 mm) and girth of scion (6.84 mm) as compared to other treatments. In case of different environmental conditions Net house condition (E₁) showed maximum growth in diameter of Root stock (53.34).
