培育一个小麦优良品种,往往需要七、八年甚至十来年时间,因为杂交后代必须经历一个性状分离的世代和性状稳定的过程。为了缩短育种年限,更快选育出新品种,近年来不少育种单位利用我国地域辽阔、气候多样的特点,在南方的昆明、庐山、井冈山等地进行夏季繁殖、异地加代,使在我国北方一年一熟的小麦也能够一年繁育二代、三代,从而大大加快了小麦新品种选育的过程。但是每年到南方夏繁加代,需要长途跋涉,耗费较多人力物力。基于这些,我们在所处的豫西山区进行小麦夏季繁殖的试验研究,以探索在本地夏繁的可能性。
It takes seven, eight or even ten years to breed a good wheat variety, because the offspring of hybrids have to go through a process of segregation of traits and stable traits. In order to shorten the breeding period and to breed new breeds faster, in recent years, many breeding units make use of the vast territory and diverse climates in our country to carry out summer breeding in different places such as Kunming, Lushan and Jinggangshan in the south, so that in northern China Wheat cooked in one year can also be bred two or three generations a year, thus greatly accelerating the breeding of new varieties of wheat. However, every year to the south of Asia, the need to travel long distances, consuming more manpower and resources. Based on these, we conducted pilot studies on summer wheat breeding in the mountainous area of western Henan to explore the possibility of local summer festivals.
