Fine mapping of the major gene BhHLS1 controlling seed size in wax gourd (Benincasa hispida).

ABSTRACT:

Introduction/background

The seed size of wax gourds is an important agronomic trait; however, the associated genes have not yet been reported.

Methods

In this study, we used a high-density genetic map constructed based on F₈ recombinant inbred line populations derived from a cross between MY-1 (large seed) and GX-71 (small seed) strains to detect quantitative trait locis (QTLs) for seed-size-related traits in wax gourd over a two-year period.

Results

Two stable QTLs (qSL10 and qSW10) for seed length (SL) and seed width (SW) on chromosome 10 were repeatedly detected over two years (2021-2022). qSL10 had a phenotypic variation rate of 75.30% and 80.80% in 2021 and 2022, respectively. Whereas, qSW10 had a phenotypic variation rate o
