Abstract

Giza 88 is an extra long staple Egyptian cotton variety. It has been introduced by the Cotton Breeding Research Section through artificial hybridization between the two parents Giza 45 and Giza 77 to combine their splendid economic qualities. Giza 88 is characterized by its extra long staple with 35.0 - 36.1mm at 2.5% span length and 17.2 -18.8 mm at 50% mean length, 4.3 -4.5 micronair reading, 154-172 militex (10-8 g/cm) for hair weight, 2680 -2980 (60$ carded) yarn strength and 37.67 -39.24 lint percent. It is also high yielding with about 10.1 k/fed seed cotton yield and 11.36 kited lint cotton yield. Moreover, it is char­acterized by its resistance to Fusarium oxysporum and F. va­si nf ectum. Giza 88 could be the bast alternative to 'Giza 70' and Giza '77' varieties.
