Other claims from this paper (15)
- Intervention effect Grain iron and zinc content increased under heat and combined stress conditions relative to control
- Observation Heritability of the traits was medium to high in the RIL population
- Association Grain iron and zinc content were moderately correlated
- Observation The linkage map spanned 14791.18 cm from 3,407 polymorphic SNP markers
- Observation QTL analysis identified 32 chromosomal regions governing the traits
- Observation Nine QTLs were identified for grain iron concentration
- Observation Eleven QTLs were identified for grain zinc concentration
- Observation Twelve QTLs were identified for thousand kernel weight
- Observation A QTL hotspot was identified on chromosome 4B
- Association The chromosome 4B QTL hotspot explained 29.28% of phenotypic variance in grain iron
- Association The chromosome 4B QTL hotspot explained 10.98% of phenotypic variance in grain zinc
- Association The chromosome 4B QTL hotspot explained 17.53% of phenotypic variance in thousand kernel weight
- Observation Common loci were identified on chromosomes 4B and 4D for grain iron, zinc and thousand kernel weight
- Observation In silico analysis identified putative candidate genes in the QTL regions
- Recommendation Markers linked to the QTLs can be used in marker-assisted selection once validated
