Introgression hybrids of the type G. hirsutum x (G. hirsutum x C. barbadense) were tested on rows with 175 units N and 92 P under full alternate-furrow irrigation. The hybrids began flowering and fruiting much earlier than check varieties Acala 1517-75 and McNair 220. Introgression hybrids were more heavily damaged by Verticillium wilt than the checks, probably due to greater fruit load on a smaller plant. Only one introgression hybrid equalled the checks in yield. We will select for parents that project higher wilt tolerance for the next generation of introgression hybrids. Interspecific hybrids grown under this same regime showed relatively low wilt damage and were highly productive. Newer, more promising isotypes of hybrid NX-1 were identified, some yielding significant higher than the checks. The season was terminated with once over harvest on October 29. Yields ranged up to 3½ bales per acre. An estimated 8-10% additional yield was sacrificed by ignoring the second harvest. This could have been as much as 150 lb/acre on some strains. However, this represents much lower quality fiber. Loss of the second harvest is well compensated by the gain of an extra month of field time needed to rotate into other crops and by avoiding the costs of running the picker over the field a second time. Total length of growing season was 179 days (May 3 Oct. 29). The target of 170 days was missed primarily because of extensive rains and cloudy weather in September and early October.
