As climate changed the favorablitiy of Secale declined.

Rye (Secale cereale) is a grass grown extensively as a grain and as a forage crop.

The snail fauna includes Abida secale, Helicella itala and Pomatias elegans.

Studies in Anatolia now suggest Rye (Secale) was cultivated, but not domesticated, prior to the holocene and to evidence for the cultivation of wheat.

The larva feeds on various grasses including Calamagrostis, Deschampsia, Festuca, Phalaris and Secale (Rye).

The larvae feed on Agropyron, Bromus, Hordeum vulgare, Melica, Secale cereale and Triticum aestivum.

Triticale, pronounced triticaily, is a cross between wheat and rye; its very name is a hybrid between that of the wheat genus, Triticum, and that of rye,Secale.

The larvae feed on Arctium, Berteroa, Bromus, Erysimum, Marrubium vulgare, Onopordum, Salvia, Secale, Stachys officinalis and Xeranthemum species.

A Middle Irish note added to the Félire Óengusso, which is of no historical value, tells that Declán was responsible for introducing rye (Irish secal, from Latin secale) into Ireland.

Gladiolus atroviolaceus, Iris caucasicus, Iris pseudocaucasica, Juglans regia, Salvia grossheimii, Allium akkaka, Asphodeline dendroides, Secale Vavilovii, Triticum boeoticum.

The use of dwarfing genes, known as Rht genes, which have been incorporated from both Triticum and Secale, has resulted in a decrease of up to 20 cm in plant height without causing any adverse effects.

The larvae of Afrotropical Delia species are mainly phytophagous, and have been found in various cereal crops and grasses, including Cynodon, Secale, Hordeum, Setaria, Pennisetum, Chloris, Sorghum, and Eleusine species.

Hybrids have been produced either between the different varieties of the same species (e.g. between non-flowering potato plants and flowering potato plants) or between two different species (e.g. between wheat triticum and rye secale to produce Triticale).

The Secale (domesticated rye) may be a very early branch from the goat grass clad (or goat grasses are a branch of early rye grasses), as branch these are almost contemporary with the branching between monoploid wheat and Aegilops tauschii.
