Abstract

One hunbred and thirteen F₅ progenies of two intervarietal Egyptian cotton (Gossypimn barbadense L.) crosses, SB 289 E X G 6002 and SIV-135 X Giza-7 were evaluated under Delhi conditions for earliness, yield, fibre quality and boll worm damage. Earliness of desirable level was achieved. In some progenies the yield was as high as that of H-14, a G. hirsutum L. Gultivar adapted to North India. Early maturing progenies had higher yield and less boll worm damage. Progenies had much higher boll number but lower boll weight than H-14. Sixteen progenies possessed extra long (33–35 mm) fibre. Twenty-eight progenies combined fine fibre, average fibre maturity and good to very good fibre strenth. Ten promising progenies were identified. The usefulness of these progenies in evolving for the first time cultivars of barbadense cottons for Northern India is discussed.
