YIELD AND FIBER QUALITY OF F1, HYBRIDS

C.G. Cook and L.N. Namken

ABSTRACT

Field studies were conducted in 1992 at Weslaco, TX to evaluate several first generation (F1) cytoplasmic male sterile-restorer cotton hybrids and Deltapine 50, the adapted commercial check cultivar for various yield components, lint yield, and fiber quality. The top ten yielding hybrids produced 15.5 to 29.9% more lint than Deltapine 50. In addition, these hybrids generally had a greater lint percent, boll weight, first harvest yield, and production rate index, while requiring fewer degree-days to first bloom and time to crop maturity. Results also indicated that fiber length, strength, and micronaire value of the hybrids were equal to Deltapine 50. Nine of the 10 top yielding hybrids were produced with fertility-restoring male parents of common ancestry, suggesting that this particular genetic background may be better for developing new fertility-restoring parents for use in hybrid cotton production programs.
