小黑麦是小麦与黑麦杂交,经人工或自然染色体加倍而培育的植物新种。国外主要采用硬粒小麦与黑麦杂交,经人工染色体加倍育成原始小黑麦类型,然后采用结实率和饱满度较好的原始六倍体小黑麦品系间杂交,提高其结实率和饱满度,育成在生产中应用的六倍体小黑麦。我国的小黑麦主要是普通小麦与黑麦杂交,经人工染色体加倍育成的,是56个染色体的八倍体小黑麦。
Triticale is a new breed of plants that is crossed by wheat and rye and doubled by artificial or natural chromosomes. Foreign mainly through the hybridization of durum wheat and rye, artificial chromosome doubling bred into the original type of triticale, and then using the seed setting rate and fullness of the original hexaploid triticale cross, to improve its seed setting rate and plumpness , Breeding into the production of hexaploid tritium. Triticale in our country is mainly a hybrid of common wheat and rye, which is bred by octagonal tritonale with 56 chromosomes.
