Agro-morphological variability of pearl millet (Pennisetum glaucum (L.) R. Br) accessions planted in arid and semi-arid region in part of Kenya

Lagat Nicholas, Paul Kimurto

The experiment was conducted in Marigat and Koibatek in Kenya from 2013 to 2014 under irrigation conditions in two environments. The main objective of the study was to investigate the morphological variability of 36 pearl millet (Pennisetum glaucum L.) accessions sourced from ICRISAT Kenya. Eight agro-morphological parameters were measured using the pearl millet descriptors. The experimental design was randomized complete block design (RCBD) with two replications. They were significantly different among all parameters measured. Thirty-six genotypes were analyzed using multivariate hierarchical cluster analysis. The hierarchical dendrogram resulted in the formation of twelve clusters depicting high level of genetic diversity among the thirty-six accessions. The results of agro-morphological parameters, that is, vegetative tillers, reproductive tillers, panicle diameter (cm), plant height (cm), panicle height (cm), panicle weight (g), 1000 seed weight (g) and grain yield (g/plant) revealed significant different at 5% level. The main objective of the study was to (1) determine Agromophological diversity of pearl millet accession in two locations and (2) evaluate yield performance of pearl millet accession in two locations.
