Comments | 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. |
