A rootstock trial was conducted on Marsh Seedless cultivar of grapefruit, using Jatti Khatti, Kharna Khatta, Troyer and Carrizo as rootstocks. The results of 20-year trial revealed that the trees budded on Troyer and Carrizo (citranges) rootstocks produced 100% survival with all the trees in healthy condition; whereas Jatti Khatti and Kharna Khatta showed only 50 and 17% survival of the trees respectively. Both the citranges also showed significantly more stock or scion girth and tree volume than Jatti Khatti rootstock. Significanlty more mean fruit yield from 1986–87 to 1996–97 was observed on Troyer and Carrizo rootstocks than on Jatti Khatti. Mean results of fruit-quality attributes showed that TSS percentage was more on Troyer than on Jatti Khatti root-stock. Heavier fruits with less peel percentage were also recorded on Troyer and Carrizo citranges than on Jatti Khatti rootstock.
