Morphological and genetic information are important for selecting rice varieties in long-grain and high-tillage rice breeding programs. One selected rice plant in the F8 generation was focused on rice plants with outstanding characteristics in the previously selected F7 rice population. The objective of this study was to select the F8 strain obtained from the F7 rice strain, which has the characteristics of short stems, tall tillers, long, slender seeds, red seeds, and has the property of being insensitive to photoperiod. Three replicate Randomized Complete Block Design (RCBD) experiments were conducted in yield test plots in farmers' areas in Phichit Province. Record data on 40 important morphological characteristics and analyze the data statistically to select only one rice strain in order to select the true strain. Testing data on product components, including number of tillers. grain length grain width and the weight of 1,000 rice grains was equal to 19 shoots, 12.0 mm., 2.8 mm., and 30.0 grams, respectively. ANOVA analysis was performed by analyzing the relationship among 40 important rice morphological characteristics. It was found that there were no differences. The difference is statistically significant at the 95% confidence level. Analysis of the index values. It was found that the highest positive correlation between seed length and flowering day was 0.587. This experiment was able to select purebred lines in the 8th generation population, leading to the registration of new rice varieties.

Morphological and genetic data are crucial for rice breeding selection in long grain and high germination rice breeding projects. A selected rice tree in the F8 series is concentrated on the rice trees with prominent characteristics in the previously selected F7 rice population. The aim of this study is to select F8 varieties from F7 rice varieties, which have low, high germination, and slender seeds. Red seeds, which are not sensitive to light, were subjected to three random and complete block design (RCBD) experiments in a production trial field in the farmers' area of Phi Province. Record 40 main morphological features and analyze statistical data, selecting only 1 rice variety. In order to select purebred, yield components were tested, including germination frequency, seed length, and seed width. The weight of 1000 grains is 19 buds, 12.0 millimeters, 2.8 millimeters, and 30.0 grams, respectively. ANOVA analysis By analyzing the relationships among 40 major rice forms, no differences were found.

Morphological characteristics and genetic information are of great significance to the selection of rice varieties. In the super-long wheat breeding project, a rice breeding plant was screened by polymers. One rice breeding in F8 model mainly focuses on the rice breeding with dominant characteristics in the previously selected F7 rice population. In this study, the F8 rice variety F7 with the characteristics of high molecular sieve, long grain, red grain and insensitive spacing was selected, and three randomized block design (RCBD) experiments were conducted. In the field yield experiment of farmers in Picasso Province, 40 main morphological characteristics were recorded, and the statistical data were analyzed and screened. 0 mm. ,2。 Eight millimeters. There are 30 more. Correlation analysis was carried out on 40 main rice morphological characteristics, and the results showed that there was no significant difference in 95% confidence level. Index analysis showed that the maximum positive correlation between seed length and flowering date was 0. The experiment of "587" can screen out the purebred of 8 malignant populations, which leads to the further registration of new rice varieties.
