| Abstract | ||
| Root depth is important for plant growth and survival during drought because of its role in water uptake from deep soil layers. The burying TRIK herbicide method has been applied to screen root depth in 138 recombinantinbredlines derived from crossing betweentwo subspecies IndicaBala and JaponicaAzucena. Analysis of mapping population revealed two putative QTLs on chromosome 6 near marker RZ682 and one on chromosome 7 near marker RG351 and two significant QTLs near marker G1010b and G1073 for root depth on chromosome 8. Positional candidate genes underneath QTLs were examined bioinformatically and through the literature revealing several interesting genes which may offer potential for developing drought resistant rice cultivars. | ||
