Resumen

A double interspecific oross {Triticum turgidum (AB) var. rubroatrum H-l-1 x Ae. ventvicosa (DM°) AP-l} x T.aestivum (ABD) cv. Almatense H-10-1S was carried out in 1950 by M. Alonso Peña (Cuenca, Spain) and 70 Unes were devived from it by vepeated selfing (Unes H-93-1 thvough 70). Pveliminavy biochemical evidence indicated genetic tvansfev fvom the M° genome of Ae.ventvicosa into some of these Unes. A more detailed biochemical and cytological characteriza tion of the H-93- Unes was undertaken. A progress report of these studies is presented here. Fourten biochemical systems, each representing a set of up to 4 homoeologous loci, weve investigated in the vavental material, in the H-93- Unes, and in Ae. squavrosa (DD), Ae. comosa (MM) and Ae. uniaristata (M^-M11). Biochemical markers controlled by the A or B genomes of one or both wheat parents weve distributed in the H-93- Unes as expected if the egcells fvom the self-stevile ABDM0 hybvid, rescued by the ABD polen, cavvied the complete A and B genomes from T. tuvgidum. The distvibution of biochemical mavkevs contvolled by the D genomes of one ov both D genome parents indicated that most of the eggcells from the ABDM0 hybrid carvied most of the D genome, i.e. 3 out of 8 markers of the former tupe were absent in a few Unes each, ind.icating incomplete homology between the two D genomes, non-homologous transfer or deletion. Biochemical characters present in Ae. ventricosa (DM°), Ae. comosa (M), Ae. uniaristata (M11) and absent in T. aestivum (ABD), Ae. squarrosa (D) and T. tuvgidum (AB) were selected as M° genome markers. Two of these markers were not transmited to the H-93- Unes, three were tvansmitted with low fvequency and one with a high fvequency. Resistance to Erisiphe graminis was determined by Dosba and Doussinault at Rennes and was found to be transmitted with low fvequency. Somatic chromosome numbers of the H-93- Unes were counted and all weve found to be hexaploid. Meiosis was studied in Unes cavvying M° genome mavkevs and in their hybrids with the T. aestivum parent, to determine the máximum numbev of alien chvornosornespvesent in each Une. The joint considevation of the biochemical and the cytological evidence se^me to indícate that the genetic tvansfev has taken place by chvomosome substitution and by vecombination.
