TABLE 7.
Quantitative trait loci (QTL) associated with abiotic stress adaptation and domestication, morpho-phenological, pod/seed size and quality traits in adzuki bean, African yard long bean, Bambara groundnut, horse Gram, moth bean, and winged bean.
| Trait group | Crop | QTL | References |
|---|---|---|---|
| Abiotic stress | Bambara groundnut | Eight QTL associated with stress tolerance index under drought stressed environments | Odesola et al. (2023) |
| Horse Gram | 7, 4, and 8 QTL associated with relative water content, root volume, and root length, respectively; genes on these marker sites involved in many biochemical pathways related to abiotic stresses | Choudhary et al. (2022) | |
| One QTL for malondialdehyde content on LG2, two QTL for root length on LG3 and LG9, one QTL each for proline and chlorophyll contents on LG4, and one QTL each for root dry weight and root fresh weight on LG 5 | Katoch and Chahota (2021) | ||
| Five QTL for four traits related to drought (days to temporary wilting, root length) and yield (seeds plant-1, days to maturity) on five LGs | Chahota et al. (2020) | ||
| Domestication related traits | African yard long bean | Between one and 11 QTL mapped on narrow genomic regions (LGs 3, 7, 8, 11); major QTL for sizes of seed, pod, stem and leaf on LG7 | Kongjaimun et al. (2012a) |
| Moth bean | Large effect QTLs with one or two minor QTLs control seed dormancy and pod shattering | Yundaeng et al. (2019) | |
| Rice bean | A few major QTL mapped as clusters on LGs 2, 4, and 7 | Isemura et al. (2010) | |
| Morpho-phenological traits | Adzuki bean | A major QTL on LG03 and two minor QTL on LG05 associated with flowering | Liu et al. (2016) |
| Horse Gram | Four QTL for phenology (flowering, reproductive period, maturity) and seven QTL for morphological (plant height, primary and secondary branches) traits across environments | Katoch et al. (2022) | |
| Pod/seed size and quality | African yard long bean | Major QTL for pod length (qPoL3) and seed breadth (qSB4), length (qSL7.2) and thickness (qST9) mapped; previously reported QTL for pod length (qPoL8) and 100-seed weight (qSW8) and for seeds pod-1 (qSN9.2) confirmed | Garcia-Oliveira et al., 2020 |
| One major and six minor QTL associated with pod length | Kongjaimun et al. (2012b) | ||
| Winged bean | 31 QTL linked with pod length, pod colour, pod anthocyanin content, and flower and seed colour; the major QTL for pod colour, anthocyanin content, and calyx colour, and for seed colour and flower wing colour located at the same position | Chankaew et al. (2022) |
