The objective of this research was to introgression of high amylose content into CH1 rice variety by using pseudo-backcrossing breeding. Crossing between CH1 and RD49 was performed to produce F1 progenies. After that, the progenies will backcross to CH1 to develop BC1F1 population. Then, the selected plants from the BC1F1 population were continuously selfed to develop BC1F2 and BC1F3 populations, respectively. For marker assisted selection, the OSR19 DNA marker that is specific to Wx gene was used for assisting the selection of plants with high amylose content in foreground selection to choose favorite genotype. Total 67 SSR markers used genetic background selection was done twice in BC1F1 and BC1F2 populations. The results showed that selection could be achieved for BC1F1 and BC1F2 plants having high amylose content and first highest ranking of genetic background similar to recurrent parent exhibited 91.04 and 97.76 percent, respectively. The marker assisted selection could accelerate 4 generations in backcross breeding program. The BC1F3 seeds of 6 selected lines were planted in paddy field for preliminary yield test. It was found that agronomic characters and yield of the selected lines were not statistically different from those of CH1 variety and high amylose content as donor parent.
The first authors would like to deliver sincere thanks to Hybrid Rice breeding for high yield and quality for industrial processing project for financial support.
