TAILIEUCHUNG - Characterization of African rice germplasm for morphological and yield attributing traits

For the establishment of the distinctness among 31 accessions of Oryza glaberrima, eight morphological traits following Distinctness, Uniformity and Stability test (DUS) studied. Out of 31 accessions studied, two accessions viz., EC861804, EC861805 were found to be highly distinct as they possessed distinct traits namely purple split ligule, medium green leaves, erect flag leaf, presence of awn along with lodging tolerance indicating their usefulness as donors for crop improvement programmes. Analysis of variance revealed significant differences for all the characters studied. Phenotypic coefficient variation was higher than genotypic coefficient variation and magnitude of PCV and GCV was high for number of productive tillers and spikelets per panicle. High heritability coupled with high genetic advance was observed for days to 50 per cent flowering and number of spikelets per panicle which suggested the presence of high additive gene action which would respond to selection owing their high genetic variability and transmissibility. | Characterization of African rice germplasm for morphological and yield attributing traits
