Abstract
Four grapefruit cultivars viz: Marsh seedless, Shamber, Red blush and Duncan grafted on Rough lemon
were evaluated in experimental field of Barani Agricultural Research Institute, Chakwal during 1999 to
2002. It was observed that Shamber and Red blush showed superiority in physical characteristics having
more than 51% juice contents with 503 to 510g/fruit weight which contained less than 31% peel and 18%
rag. However, Duncan fruit occupied lowest rank in juice contents (44.9%) with maximal weight of fruit
(539g/fruit), peel (33.6%) and rag (21.2%). Analysis of chemical characteristics indicated that Shamber
dominated in acidity (1.56%) while Duncan secured top position in TSS (8.02%) and TSS acid ratio (5.94).
Fruit yields showed non significant results among the cultvars.
