ประเมินลักษณะทางการเกษตร ผลผลิต และองค์ประกอบผลผลิตของข้าว ดับเบิลแฮพลอยด์ด้วยวิธีการเพาะเลี้ยงอับเรณูสายพันธุ์ก้าวหน้า

    Rice is a major economic crop in Thailand, therefore, it is important to develop high-potential rice varieties. The application of in vitro anther culture to produce doubled haploid (DH) rice plays a significant role in accelerating the development of pure lines and reducing genetic variability. This study aimed to evaluate the agronomic traits, yield, and yield components of five advanced DH rice lines derived through anther culture (DSAC- to DSAC-) and two check varieties (RJ and Pathum Thani  ǰThe experiment was conducted during the dry season using a randomized complete block design with four replications.The results revealed that three advanced DH lines: DSAC-, DSAC-, and DSAC- were selected based on their superior performance. These lines exhibited high grain yields ranging from  to  kg/rai, earlier  flowering and shorter maturity periods compared to both check varieties. In addition, these lines showed favorable agronomic traits, including plant height (ı cm), panicle length (ı cm), number of grains per panicle (ı grains), and number of filled grains (ı grains), which were either superior to or not significantly different from the check varieties. These findings demonstrate the potential of these doubled haploid rice lines for development into new, high-quality rice varieties that can meet future market demands.
