Abstract

Earliness per se (Eps) genes are reported to be important in fine-tuning flowering time in wheat independently of photoperiod (Ppd) and vernalisation (Vrn). Unlike Ppd and Vrn genes, Eps have relatively small effects and their physiological effect along with chromosomal position are not well defined. We evaluated eight lines derived from crossing two vernalisation insensitive lines, Paragon and Baj (late and early flowering respectively), to study the detailed effects of two newly identified QTLs, Eps-7D and Eps-2B and their interactions under field conditions. The effect of both QTLs was minor and was affected by the allelic status of the other. While the magnitude of effect of these QTLs on anthesis was similar, they are associated with very different profiles of pre-anthesis development which also depends on their interaction. Eps-7D affected both duration before and after terminal spikelet while not affecting final leaf number (FLN) so Eps-7D-early had a faster rate of leaf appearance. Eps-2B acted more specifically in the early reproductive phase and slightly altered FLN without affecting the leaf appearance rate. Both QTLs affected the spike fertility by altering the rate of floret development and mortality. The effect of Eps-2B was very small but consistent in that -late allele tended to produce more fertile florets.

摘要

早熟基因（Eps）被报道在独立于光周期（Ppd）和春化（Vrn）的情况下微调小麦开花时间方面起着重要作用。与 Ppd 和 Vrn 基因不同，Eps 的影响相对较小，其生理效应及其染色体位置尚不清楚。我们评估了来自两个春化不敏感系 Paragon 和 Baj（分别为晚花和早花）杂交的 8 个系，以研究两个新鉴定的 QTLs（Eps-7D 和 Eps-2B）及其在田间条件下的相互作用的详细影响。这两个 QTL 的效应都很小，并且受到其他等位基因状态的影响。虽然这些 QTL 对开花的效应幅度相似，但它们与不同的开花前发育特征相关，这也取决于它们的相互作用。Eps-7D 影响小穗顶端前后的持续时间，但不影响最终叶片数（FLN），因此 Eps-7D-early 的叶片出现速度更快。Eps-2B 在早期生殖阶段的作用更为具体，略微改变了 FLN，但不影响叶片出现率。这两个 QTL 都通过改变小花发育和死亡率来影响穗粒结实率。Eps-2B 的影响很小，但很一致，即-late 等位基因往往会产生更多的可育小花。
