ID 42509
Name DQC13 (QTL ACCESSION {description)
Synonyms (1) DQC13-PENTRTRO
TO TERM {descriptionTO:0000510 (penetrated to total root ratio)
Trait Namepenetrated to total root ratio
Trait SymbolPENTRTRO
Type QTL
Species Oryza sativa (Oryza sativa) [ GR_tax:013681 ]
Germplasm
Description Recombinant inbred lines derived from a cross of two drought-resistant
varieties, Bala and Azucena) were used for QTL mapping. Plants were planted in a
controlled environment room. Tiller number, total and penetrated root number and
the ratio of penetrated:total root number were evaluated 24 days after planting.
Root penetration ability was evaluated using a wax-petrolatum layer according to
Yu et al.(1995).For QTL analyses, mean values from the two runs were used. QTLs
were declared significant if single-marker regression gave a significance of 1%.
Positioning of QTLs was achieved by composite interval mapping, conducted using
the program QTLcartographer.
