从优良四倍体品种生产双单倍体是寻求简化马铃薯遗传学的传统和新型育种方法的关键。为此,需要高效且广泛相容的单倍体诱导剂(HI)。我们将国际马铃薯中心开发的新 HI PL-4 与已知的 HI IvP101 和 IvP35 进行了比较。通过对优良四倍体育种系进行授粉,我们发现 PL-4 在最重要的效率性状(每 100 个果实中的双单倍体数量和单倍体诱导率)上表现明显更好,并且无论雌蕊亲本的遗传背景如何,都具有均一的响应。此外,PL-4 表现出杂种种子比例降低,这是有效筛选的便利特征。在这种情况下,我们推荐 PL-4 作为马铃薯育种界的增强型 HI。
Dihaploid production from elite tetraploid cultivars is key to both traditional and novel breeding approaches that seek to simplify potato genetics. For this purpose, efficient and widely compatible haploid inducers (HIs) are needed. We compared PL-4, a new HI developed at the International Potato Center, to known HIs IvP101 and IvP35. By pollination of elite tetraploid breeding lines, we showed that PL-4 performed significantly better and had a homogeneous response regardless of the genetic background of the pistillate parents, on the most important efficiency traits—number of dihaploids per 100 fruits and haploid induction rate. Moreover, PL-4 exhibited a reduced proportion of hybrid seeds, a convenient trait for efficient screening. In this context, we recommend PL-4 as an enhanced HI for the potato breeding community.
