农林系统的起源,已知来自下列杂交:Fultz×Paruma(1917) Fultz-Paruma×Turkey Red (1924)=Norin 农林衍生物的矮性,可在许多半矮型品种中找到。Tarakanov等人(1970)认为农林10号实质上在小麦育种历史上打开了新的一章。它是国际上公认的新半矮型品种(如Gaines、Pitc 62、Lerma Rojo 64、Sonora 64、Inia 66等)的一个祖先(Reitz,1970)其矮性是由2个不完全隐性基因(Sd1、Sd2)所引起的(Allan,1970)。育种工作者在认识了矮型生长的固有优点以后,又找到了更好的矮源,这就是他们所要求的冬型品种大姆指矮(C.I.13563)通过单 The origins of agroforestry systems are known from the following hybridizations: Fultz × Paruma (1917) Fultz-Paruma × Turkey Red (1924) = The dwarfity of Norin agroforestry derivatives is found in many semi-dwarf varieties. Tarakanov et al. (1970) argues that Agriculture, Forestry and Forestry 10 actually opened a new chapter in the history of wheat breeding. It is an ancestor of internationally recognized new semi-dwarf varieties such as Gaines, Pitc 62, Lerma Rojo 64, Sonora 64, Inia 66, etc. (Reitz, 1970), which is composed of two incomplete recessive genes (Sd1 , Sd2) (Allan, 1970). After recognizing the inherent advantages of short growth, breeders found a better source of dwarfness, which is what they called the winter-type cultivar Diminu (C.I. 13563)
