SCREENING FOR SEED FERTILITY AND PLOIDY IN Musa SPP Ukwueze, C.K., Oselebe, H.O. and Nnamani, C.V.   ABSTRACT Musa species (spp) comprise genotypes with varying ploidy and fertility levels which limit seed production and damper its improvement. This study was aimed at assessing the ploidy and fertility of 11 Musa accessions in the germplasm held … Read more

PLOIDY DETERMINATION OF Musa GERMPLASM USING MORPHOLOGICAL DESCRIPTORS AND CHLOROPLAST COUNT IN PAIRS OF STOMATAL GUARD CELLS Ukwueze, C.K., Oselebe, H.O. and Nnamani, C.V.   ABSTRACT Musa species comprise different ploidy natures with most cultivated species being triploid. This results in its sterility and limits improvement. This work was aimed at determining the ploidy nature … Read more

Induced Mutation Although mutations are changes in an organism’s DNA, some do not cause panic and do not attract research interest. This is because such mutations are not spontaneous, instead, they are induced, hence, expected. Therefore, induced mutations are mutations that arise after purposeful treatment with mutagens. Their cause is known, therefore, there is no … Read more

Spontaneous Mutation Mutation, being a change in the nucleotide sequence of a gene could be lethal. Although, some are not lethal even when they cause serious changes in the gene expression of the individual. That is because such change is to be recorded and examined. But that area will be in my next academic meal … Read more
