Fine mapping and candidate gene analysis of major QTLs for number of seeds per pod in Arachis hypogaea L.

ABSTRACT:

Background

Peanut (Arachis hypogaea L., 2n = 2x = 20) is an important industrial and oil crop that is widely grown in more than 100 countries. In recent years, breeders have focused on increasing the seed number per pod to improve their yield in addition to other breeding for other key components of yield, including the pod number, seeds per pod, and 100-seed weight.

Results

In this study, a secondary population of 1,114 BC₁F₂ lines was derived from a cross between the parents R45 and JNH3. Two stable major-effect quantitative trait loci of qRMPA09.1 and qRMPA09.2 were detected simultaneously and mapped within chromosomal intervals of approximately 400 Kb and 600 Kb on chromosome A09. Additionally, combined whole-genome and RNA sequencing analyses showe
