ABSTRACT

Experiment on morphological characterization of natural rubber (Hevea brasiliensis) genotypes was carried out during the 2021 cropping season. The experiment was set up at clonal garden of Rubber Research Institute of Nigeria (RRIN) Iyanomo, Benin City. The objective of the study was to characterize available natural rubber genotypes with a view to classifying them into distinct similarity groups using natural rubber descriptor manual. Morphological descriptor traits were used to characterize 16 genotypes of natural rubber at mature stage using RRIN and IPGRI, 2005 descriptor manual for natural rubber. The two parts of the natural rubber trees characterized included the trunk and branching. Data on yield evaluation was also collected using the taping system for all the sampled trees on a half spiral alternate day system donated as S/2d/2 without yield stimulation and the dry rubber yield data collected were subjected to analysis of variance (ANOVA) using the Generalized Mixed Model to determine the variability that existed among the genotypes. Frequency distribution for qualitative characters showed that rubber genotypes had considerable variations for most trunk and branching descriptor traits measured. Combined analysis of variance (ANOVA) indicated highly significant genotypic differences among the genotypes for the agronomic character (latex yield) measured. In conclusion, the information obtained from this research work showed that considerable genetic variability exists in agro-morphological attributes of natural rubber genotypes. Genotypes with highly similar traits and high-yielding potentials have been identified and characterized.
