APPLICATION OF MARKER ASSISTED BACKCROSSING TO SELECT THE INDIVIDUAL PLANTS OF BC3F1 POPULATION CARRYING THE QTL/GENE TO IMPROVE YIELD OF KD18
Rice (Oryza savita L.) is the most important food crop, and staple food for many people in the world. However, the pressure of rapid population growth, adverse effects from climate change and limited areas of rice growing in the country due to the urbanization and industrialization that need to urgently enhance rice yield to meet the increasing demands of food – consuming. Molecular breeding such as Marker – Assisted Backcrossing (MABC) is one of the efficient methods to transfer the specific quantitative trait loci (QTL) or gene into the elite varieties. In this study, MABC was applied to transfer QTL/gene which is responsible for trait of increasing number of grains per panicle from donor (KC25) to recipient plant (KD18). The results have shown that the successfully selected individual No 14 in BC3F1 population carrying QTL/gene and attained the highest genetic background of the recipient plant up to 100% were made.
