Mapping of quantitative traits LOCIS (QTLS) for plant height in rice

Author(s): Mahendra S Dudhare, Ramesh N Dhawale and SK Mishra

Abstract: A double haploid mapping population consisting of 75 lines of a cross between the irrigated indica variety IR64 and the upland japonica variety Azucena was used in the present experiment. The complete set of double haploid lines along with parents was evaluated under two sets of conditions, 1. Transplanted with water stress and 2. Transplanted with no stress over two years. Water stress was imposed at flowering and observations were recorded for plant height traits. A total of five putative QTLs for plant height were detected, which were found to be explaining a minimum of 10.4 per cent to maximum of 17.8 per cent of phenotypic variation, individually. These QTLs were mapped on the rice genome and linked DNA markers have been validated for use in the marker assisted breeding program.
