Data from: QTL mapping genotype and phenotype data, Vanilla x MCM5001

Pod quality and yield traits in snap bean (Phaseolus vulgaris L.)
influence consumer preferences, crop adoption by farmers, and the ability
of the product to be commercially competitive locally and globally. The
objective of the study was to identify the quantitative trait loci (QTL)
for pod quality and yield traits in a snap × dry bean recombinant inbred
line (RIL) population. A total of 184 F6 RILs derived from a cross between
Vanilla (snap bean) and MCM5001 (dry bean) were grown in three field sites
in Kenya and one greenhouse environment in Davis, CA, USA. They were
genotyped at 5,951 single nucleotide polymorphisms (SNPs), and composite
interval mapping was conducted to identify QTL for 16 pod quality and
yield traits, including pod wall fiber, pod string, pod size, and harvest
metrics. A combined total of 44 QTL were identified in field and
greenhouse trials. The QTL for pod quality were identified on chromosomes
Pv01, Pv02, Pv03, Pv04, Pv06, and Pv07, and for pod yield were identified
on Pv08. Co-localization of QTL was observed for pod quality and yield
traits. Some identified QTL overlapped with previously mapped QTL for pod
quality and yield traits, with several others identified as novel. The
identified QTL can be used in future marker-assisted selection in snap
bean.
