Inheritance and Quantitative Trait Locus Mapping of Fusarium Wilt Resistance in Cucumber.

ABSTRACT: Fusarium wilt (FW) is a very serious soil-borne disease worldwide, which usually results in huge yield losses in cucumber production. However, the inheritance and molecular mechanism of the response to FW are still unknown in cucumber (Cucumis sativus L.). In this study, two inbred cucumber lines Superina (P₁) and Rijiecheng (P₂) were used as the sensitive and resistant lines, respectively. A mixed major gene plus polygene inheritance model was used to analyze the resistance to FW in different generations of cucumber, namely, P₁, P₂, F₁ (P₁×P₂), B₁, and B₂, obtained by backcrossing F₁ plants with Superina (B₁) or Rijiecheng (B₂), and F₂
