Laghari 6200216An experiment was designed to study the morphological and yield behavior of nine exotic and one local cultivar of tomato under Islamabad conditions. Characters studied were time required to flowering, fruit setting, fruit ripening, yield/plant and yield ha-1. Significant difference in the parameters except days to maturity were observed which could be attributed to inherited differences among cultivars. Cultivar marmande (TMV) took significantly minimum time (65.0 days) to ripen followed by S. marzano which ripened in 72.3 days. Cultivar polefemo ripened late (91.7 days) followed by marmande which took 88.7 days to ripen. Cultivars marmande TMV and marmande out yielded other cultivars with 64.29 and 62.99 t ha-1, respectively while poor yield was obtained in S. marzano (14.90 t ha-1).]]>Anonymous,1999Chaudhry, M.F., K.M.
