520 _aAn experiment was conducted at Giza Research Station during 2002, 2003 and 2004 to study some morphological & anatomical features of eight parental genotypes and twelve of their partial diallel FI crosses. Five Egyptian cotton cultivars (Giza 91, Giza 90, Giza 70, Giza88 and Suvin) of the species barbadense and three lines belonging to the species hirsutum (Frego bract, Okra leaf and Nectariless) were applied. The Egyptian parents surpassed those of the upland cotton with respectto main stem length, main stem diameter and the leaf thickness. Highest values of lobing index & central leaf lobe s~hape recorded for the Okra leaf and Nectari/ess lines. Leaves of both varied morphologically (drastically lobated & narrower lobes) from the wider leaves of the other parents. No specific anatomical variations were noted between both leaf types. Crossing between Okra Ieaf type with three Egyptian cultivars resulted F1 hybrids with Okra leaf shape. Considerably, higher values of leaf nectaries length were recorded for GiZa 90 and all of its crosses. Morphological study showed that most of the inter-specific hybrids performed better over parents and intra¬specific ones which may be interpreted by hybrid vigour.
