Genetic diversity of upland rice germplasm in Malaysia based on quantitative traits


Sohrabi, Mehdi and Yusop, Mohd Rafii and Musa, Mohamed Hanafi and Abdullah, Siti Nor Akmar and Latif, Mohammad Abdul (2012) Genetic diversity of upland rice germplasm in Malaysia based on quantitative traits.

Genetic diversity is prerequisite for any crop improvement program as it helps in the development of superior recombinants. Fifty Malaysian upland rice accessions were evaluated for 12 growth traits, yield and yield components. All of the traits were significant and highly significant among the accessions. The higher magnitudes of genotypic and phenotypic coefficients of variation were recorded for flag leaf length-to-width ratio, spikelet fertility, and days to flowering. High heritability along with high genetic advance was registered for yield of plant, days to flowering, and flag leaf length-to-width ratio suggesting preponderance of additive gene action in the gene expression of these characters. Plant height showed highly significant positive correlation with most of the traits. According to UPGMA cluster analysis all accessions were clustered into six groups. Twelve morphological traits provided around 77% of total variation among the accessions.
