ABSTRACT

This study was carried out at Umudike Longitude-0733E, Latitude -0529N; and altitude of 122m during the2018 and 2019 cropping seasons to evaluate six taro genotypes namely Nce 001, Nce 002, Nce 003, Nce005, Nce 010 and Nce 011. The relationship between their growth, yield and yield stability attributes was studied with a view to determining the most important indices for yield improvement. The experiment was laid out using a randomized complete Block Design (RCBD) with treatments replicated 4 times. Plot size was 2m by 3m. Data collected included plant height (cm), number of leaves per plant, leaf area per plant (cm2), girth size per plant, number of suckers per plant, number of corms per plant, number of cormels per plant, weight of corms per plant, weight of cormels per plant and yield (t/ha). Results obtained indicated the presence of genetic variability among the taro landdraces for the different traits under consideration. Cormel number, cormel weight and corm weight showed significant positive correlation with yield at p<0.05 suggesting that a  direct relation for these traits will lead to taro yield improvement. Multiple regression, coefficient of determination R2 and R change (R2) showed that three attributes namely cormels weight, corms weight and plant height were the largest contributor to yield (t/ha). These three attributes significantly predicted and explained 79.8% of total yield observed. The study also showed that Nce 011 (4.45 t/ha, 4.41 t/ha) and Nce 003 (4.38 t/ha, 4.41 t/ha) consistently gave the highest yield in 2018 and 2019; an indication  that these two genotypes could be selected in further hybridization.
