Data on 2,744 calves produced in Clay Center, Nebraska and Brookville, Florida were used to evaluate the importance of genotype x location interactions on the reproductive and materna performance of eight breed groups of F1 crosbred cow. A total of 648 F1 crossbred cows include Bos taurus x Bos taurus (Bt x Bt) crosses: Hereford x Angus reciprocal crossbreds (HA and AH), Pinzgauer x Angus (PA), Pinzgauer x Hereford (PH) and Bos indicus x Bos taurus (Bi x Bt) crosses: Brahman x Angus (BA), Brahman x Hereford (BH) Sahiwal x Angus (SA) and Sahiwal x hereford (SH). The first calf crop was sired by Red Poll bulls. All remaining calf crops were sired by simmental bulls. Although the pregmancy rate was 9% higher in Nebraska the rate of unassisted calving and calfsurvival rate were both 4,6% lower in Nebraska Calf birth and weaning weigth were 8.0 and 15.6 kg heavier in Nebraska than in Florida. Bi x Bt dams exceded (P v.001) Bt x Bt crossbred dams for all traits except age of calf at weaning and calf-survival rates (P >.10). Birth weights of calves from Bi x Bt crossbred dams were 3.4 kg lighhter than those from the Bt x Bt crossbred dams. The interactions of location with the breed group comparison of Bi x Bt vs Bt x Bt crossbred dams was significant for pregnancy rate, calf age at weaning, rate of unassisted calving and al weight traits. Adjusted weaning weights of calves from Ha, AH, PA, PH, BA, BH, BH, Bh, SA and SH cows were as follows: HA, 194 and 222, AH, 202 and 230; PA 213 and 242; PH, 217 and 245;...
