The performance of two lemon cultivars namely Feminello and Eureka lemon (Citrus limon (L.) Brum.f), four orange cultivars namely navel orange (Navelina, Navelate, Newhall and Washington navel orange (Citrus sinensis L. Osbeck)) and four mandarin cultivars namely seedless mandarin, thorny Clementine, thornless Clementine and Balady mandarin (Citrus reticulata Blanco), respectively were done at South El Tahrir research station, Beheira Gov. during 2006/2007 and 2007/2008 under similar cultural practices. Preliminary observations under the prevailing conditions indicated that Feminello lemon, Newhall navel orange, Washington navel orange and both thornless and thorny Clementine were excellent with an average 7.46, 6.87, 6.45 and 6.58 ton/fed, respectively whereas Navelina, Navelate and Balady and seedless mandarin occupied the second position. However, the vegetative growth of the promising varieties was directly proportional to root horizontal and vertical extension.
