Morphological Characterization of Jute Mallow (Corchorius olitorius L.) Accessions in Minna, Niger State, Nigeria
Abubakar, M.L., Ibrahim, H. and Gana, A.S.
In sub-Saharan Africa, including Nigeria, jute mallow (Corchorus olitorius) is a major leafy vegetable. Unfortunately, the sub-region has a scarcity of reported improved varieties. Data on the morphological and yield characteristics of locally available accessions would be essential for breeding purposes. This study investigated the height and leaf production diversity of 26 Corchorus olitorius accessions. During the cropping seasons of 2020 and 2021, the experiment was conducted in Minna, in Nigeria’s Northern Guinea Savanna ecological zone. A randomised complete block design with three replicates was used. Plant height and number of leaves per plant were assessed at 2, 4, and 6 weeks after transplanting (WAT). The data were subjected to analysis of variance, and means were separated using Student-Newman-Keuls at a 5% probability level. Plant height and number of leaves per plant showed a wide range of genetic diversity. It was observed that the accessions NGB 00190 (73.7 cm tall; 162 leaves/plant) and NGB 00197 (70 cm tall; 220 leaves/plant) combined tallness with leaf abundance. Further genetic improvement of these promising accessions would contribute to nutrition and healthy living in the country.
