Vernalization response was determined in an annual and two biennial celery strains, Apium graveolens L. and their F2 hybrids. Although the annual strain did not require vernalization to bolt, plants exposed to 10°C for 7 days bolted 2 weeks earlier than non-treated plants. Inheritance studies based on F2 and backcross segregations demonstrate that annual habit in celery is partially dominant over biennial and determined by a single gene designated Hb. Cosegregation studies of this trait with nine isozyme loci and a gene determining petiole anthocyanin pigmentation disclosed the following linkage relationships: Adh-1-Sdh-1-Mdh-1, and Got-1-Mdh-2-Hb-A. The recombination frequency observed for Hb and Mdh-2 was too large to use the latter as a useful marker for annual habit.
春化反应在一年生和两年生的芹菜品种,即 Apium graveolens L. 及其 F2 杂种中进行了测定。虽然一年生的芹菜品种不需要春化就可以抽薹,但在 10°C 下处理 7 天的植株比未处理的植株早 2 周抽薹。基于 F2 和回交分离群体的遗传研究表明,芹菜的一年生习性在两年生之上是部分显性的,由一个单一的基因 Hb 决定。该性状与九个同工酶基因座和一个决定叶柄花青素色素沉着的基因的共分离研究揭示了以下连锁关系:Adh-1-Sdh-1-Mdh-1,和 Got-1-Mdh-2-Hb-A。观察到 Hb 和 Mdh-2 之间的重组频率太大,不能将后者用作一年生习性的有用标记。
