Analyzing Genetic Variability and Heritability in Rice Breeding: A Focus on Yield Improvement

Hasina Begum [3]


Abstract: This study assesses the genetic variability and heritability of 19 agronomic traits in 431 elite rice breeding lines. Conducted in two seasons at the International Rice Research Institute, it aimed to identify traits predictive of improved rice yield. Significant genetic variability was observed, with traits like filled grains per plant showing a strong positive correlation with yield. High heritability was found for most traits, indicating their potential for use in targeted breeding programs. The study concludes that selecting for specific traits like panicles and filled grains per plant is crucial for enhancing rice yield.
