Studies on comparative performance of various genotypes of mango for wedge grafting with polytube capping

Abstract

The present investigation was conducted at Horticulture Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) during the year 2016-2017 in kharif and rabi season. The treatments consisted of combinations of three genotypes of mango (Dashehari, C.G. Achar and C.G. Swarnaprabha) three duration of defoliation of scion (4, 8 and 12 days) and with covering and without covering of grafts with poly tube till sprouting. The growth observations including girth of rootstock, scion and sprout, length of sprout, number of leaves per graft, total height of grafted plant, days taken for first and last sprouting, percentage of graft sprouting, establishment and survival were recorded at 30 days interval up to 180 days of grafting. The result on individual effects indicated that genotype Dashehari significantly increased early sprouting, girth of rootstock, girth of scion, girth of sprout, sprout length, number of leaves per graft, plant height, higher establishment and survival percentage followed by genotype C.G. Achar.
