Over one fourth of plant species are natural araphiploids (1). Triticale species are synthetic amphiplolds obteined by duplication of chroraosome numbor in sterile hybrids resulting frora internpecific crossee between speciea of the genus Triticum and rye (Sécale cereale). Pertinent literature concerning these synthetic speciea has boen recently reviewed by BRIGGLE (2). The first Triticale was obteined by RIMPAU in 1891 from a croas between hexaploid wheat and rye, In 1934, MÜHTZING (3) started a breeding prográmale to obtsin lines of octaploid Triticale for practical use» In 1950, SANCHEZ-MONGE atarted a similor programme to obtain triticales with 42 chromosomes and suggected that this ploidy level should be nearer the optimua than the octaploid (4, 5). In 1954, a Canndian prográmele to obtain high yield triticales v/aa initiated (6). As a result of these and other efforte, Triticale varieties are about to be released, SANCHEZ-MOITGE, at the Instituto Nacional de Investigaciones Agronómicas in Madrid, is nultiplying the hexoploid variety "Cachirulo" for its immedla'te diffusion. Originally, this variety was intended as a substitute of rye, barley or oatB for animal feeding; and whole crop silage is quite s8tisfactory (7). However, its high yield under irrlgation has led us to reconsider its utilization as a wheat substitute. As a result of seed shriveling, triticale has a greater proportion. of peripheric endosperm and, consequently, a markedly higher protein content than wheat (20 % for triticale versus approximately 11 % for most Spanish wheets). On the other hand, seed shriveling results in lower milling yield. Improvement of triticale grain by breeding concomltantly reduces protein content.
