Abstract:
In the experiment was done to investigate the correlation analysis of 10 traits, namely the number of days 50% flowering, plant height, total production tiller per hill, ear length, grain length, grain width, grain ratio 1000 seeds weight, also known as test weight, days to first harvest, and yield of a single plant among 64 rice DH lines and 2 parents. The genotype correlation coefficient is larger than the phenotypic correlation coefficient, indicating the masking or altering effect of the environment. Genetic correlations showed that single plant yields had a strong positive and significant association with total productive tiller at the genotype level. From this it can be concluded that the total grain yield and total productive tiller can be used as a selection criterion for improving grain yield per plant. Therefore, traits should be considered in breeding programs to develop maximum threshold yields for new rice varieties or hybrids.
