From the experiment, it was found that the 5 selected rice strains from the breeding line population, all 5 strains in the 7th generation, had morphological characteristics according to the criteria for recording 40 morphological characteristics. It was found that the strains that One outstanding strain has morphological characteristics used in selecting candidate breeding lines in the eighth population, namely the number of shoots per clump, seed length, seed width and weight of 100 seeds, namely strain no. 3, there are 3. The plants have the highest number of shoots per clump, equal to 18 plants, 19 plants, and 16 plants, respectively. They have the highest seed length characteristics, equal to 11 mm., 12 mm., and 10 mm., respectively. The highest seed width length are equal to 2.9 mm., 2.8 mm. and 2.7 millimeters, respectively, and had the highest seed weight of 100 seeds, equal to 4 grams, 4 grams, and 4 grams, respectively. The best purebred strains were selected from the highest characteristics in order to affect the increased yield. It was found that the second plant was the best pure line and had genetics of homozygosity, which led to the registration of a new rice variety.
