54 Journal of Plant Registrations, Vol 1, May–June 2007 In common tests with Deltapine 493 (DP493) the lint yield of LA1110017 was 153 kg ha−1 less, signifi cant at P = 0.05. The lint fraction of LA1110017 (40%) was signifi cantly lower than that of PSC355 at 42% and also signifi cantly (P = 0.05) lower than that of DP493 (46%). The fi ber length of LA1110017 (30.2 mm) was signifi cantly greater than that of PSC355 (28.2 mm) or DP493 (28.2 mm). The fi ber strength of LA1110017 (346 kN m kg−1) was signifi cantly greater than that of PSC355 (317 kN m kg−1) and also of DP493 (291 kN m kg−1). Signifi cantly lower micronaire values existed in LA1110017 than in DP493 and in PSC355. Elongation mean values for LA1110017 were signifi cantly lower in comparison to PSC355 but signifi cantly greater than DP493. Greater fi ber length uniformity was evident in LA1110017 than in either PSC355 or DP493 with the highest mean values associated with LA1110017. LA1110017 provides cotton breeding programs looking to improve fi ber quality an improved fi ber package, notably in the areas of length and strength. The highly competitive yield of LA1110017 would imply that these traits could be introgressed without a concomitant yield penalty. Small quantities of seed will be available for distribution and may be requested from the senior author. Unless specifi cally approved by the Louisiana Agricultural Experiment Station, LA1110017 may not be used as a recurrent parent in a breeding program.
