“…One of the first study regarding crossability between wheat and wheat relatives was published about a century ago (Backhouse, 1916) and showed that crossability between wheat and rye was a recessive trait. These results were further confirmed (Leighty and Sando, 1928;Meister and Tjumjakoff, 1928;Riley and Chapman, 1967;Taylor and Quisenberry, 1935).…”

Summary In the recent years, the agricultural world has been progressing towards integrated crop protection, in the context of sustainable and reasoned agriculture to improve food security and quality, and to preserve the environment through reduced uses of water, pesticides, fungicides or fertilisers. For this purpose, one possible issue is to cross‐elite varieties widely used in fields for crop productions with exotic or wild genetic resources in order to introduce new diversity for genes or alleles of agronomical interest to accelerate the development of new improved cultivars. However, crossing ability (or crossability) often depends on genetic background of the recipient varieties or of the donor, which hampers a larger use of wild resources in breeding programmes of many crops. In this review, we tried to provide a comprehensive summary of genetic factors controlling crossing ability between Triticeae species with a special focus on the crossability between wheat ( Triticum aestivum L.) and rye ( Secale cereale ), which lead to the creation of Triticale ( x Triticosecale Wittm.). We also discussed potential applications of newly identified genes or markers associated with crossability for accelerating wheat and Triticale improvement by application of modern genomics technologies in breeding programmes.

“…Tools had now become available to systematically produce new and fertile amphidiploids in unlimited numbers and conduct research on a larger scale. Taylor & Quisenberry (1935) stated that crossability (i.e. seed set irrespective of the viability of the embryo) of wheat-rye crosses was a heritable character.…”

Triticale (×Triticosecale Wittmack) is the intergeneric hybrid between the female parent wheat (Triticum ssp.) and the male parent rye (Secale ssp.). The early work identifying and then producing primary and secondary triticales is described. Early wheat–rye hybrids were characterized by reproductive disorders and the cytology and meiotic characteristics have received much attention. Chromosome constitution has been studied particularly in relation to R-D substitution. Triticale has always been bred as a self-pollinating crop, although outcrossing can occur, and current cultivars are all nearly homozygous and homogeneous lines. Hybrid breeding (using cytoplasmic male sterility) makes the optimum exploitation of heterosis possible and, with the aid of molecular markers, triticale germplasm is presently being investigated to establish genetically diverse heterotic groups.The first released spring and winter cultivars were generally characterized by good disease resistance, but low grain yield, shrivelled grain, high protein content, excessive height, lodging and preharvest sprouting. Breeding effort has increased yield, reduced shrivelling and improved test weight but at the expense of protein content, which is now comparable to wheat and rye. Plant height and lodging are also now comparable to wheat and rye. Progress in reducing preharvest sprouting by genetic selection is proving difficult and slow. Triticale may be suitable for grain production and for dual purpose usage for forage and grain.The role of biotechnology in triticale improvement is described. The future of the crop, especially in low-input systems, and as raw material for industrial uses is considered.

“…The ability of wheat and rye to cross was reported to be controlled by one (Taylor and Quisenberry, 1935) or by two recessive genes, kr1 and kr2 (Lein, 1943) in wheat. In contrast, dominant genes in S. cereale control crossing with wheat (Tanner and Falk, 1981).…”

Introgression between cultivars and wild relatives is common in several angiosperm taxa including the grass family Poaceae. Bread wheat (Triticum aestivum L.) is a domesticated allohexaploid species (genome formula BBAADD) without any known wild hexaploid relative in the genus Triticum Bread wheat is also related to the genus Aegilops L., which has probably contributed two of the three genomes of bread wheat. A few tetraploid Aegilops species, including Ae. cylindrica Host. and Ae. triuncialis L., occur as weeds both in the Mediterranean basin and in West Asia. Introduced populations of these weeds are also known to occur in North America. These species have been known to introgress occasionally with bread wheat when grown near wheat fields. Similarly, rye (Secale cereale L.), a species from a distant genus, has a potential to introgress with bread wheat. A few natural introgressive hybrids between herbicide resistant wheat and Ae. cylindrica and between wheat and rye have been created or recovered in North America. Natural hybrids between wheat and Ae. triuncialis have not been observed in North America. The available data do not suggest the prevalence of large‐scale introgression between bread wheat and its wild relatives in North America. Nevertheless, with modern bread wheat cultivars being developed with novel traits, such as herbicide and disease resistance, an in‐depth evaluation of the extent and nature of introgression between weedy Aegilops or Secale species and bread wheat is useful both for assessing potential ecological risks that may be associated with trait presence in hybrids and for formulating strategies to manage gene transfer to hybrids. In this review, we discuss the existing literature on reproductive ecology of bread wheat and on introgression between bread wheat and its wild relatives in the genera Aegilops and Secale that occur in North America. We also discuss the implications of introgression in consideration of the current and possible future development of transgenic wheat.
