Abstract
Telocentrics of hexaploid wheat, Triticum aestivum spp. vulgare cv. Chinese Spring, were used to establish the chromosome arm location and crossover distance from the centromere of genes controlling characters introduced into synthetic hexaploid wheat (2n=42=AABBDD) from Aegilops squarrosa (2n=14=DD). The chromosome arm location and the crossover distance from the centromere of each gene studied are as follows: synthetic hexaploid RL 5404 - brown glumes (Rg2), 1DL, 13.3 +/- 3.3%; tenacious glumes (Tg), 2Da, 39.4 +/- 4.9%; inhibitor of waxy foliage (W21), 2Da, 52.5 +/- 5.0%; adult-plant leaf rust resistance (Lr22), 2Da, 63.6 +/- 4.8%; purple coleoptile (Rc3), 7DS, 10.3 +/- 2.8%; synthetic hexaploid RL 5406 - Rg2, 1DL, 1.7 +/- 1.0%; Tg, 2Da, 42.9 +/- 4.6%; W21, 2Da, 58.9 +/- 4.6%; Rc3, 7DS, 9.8 +/- 2.8%. A gene for seedling leaf rust resistance (Lr21) found in RL 5406 is located on chromosome 1D.
