Abstract
Many research works done on Black Cumin focused on its nutritional and medicinal properties. As a result, there is no information on the association of its yield and yield components. Therefore, correlation analysis was made on twenty Black Cumin landraces evaluated at Goro and Ginir districts of Bale in randomized complete block design with three replications during 2011 and 2012 to quantify the relationship between yield and yield components. The result of the analysis showed that seed yield is positively correlated with plant height (0.40), number of capsules per plant (0.12), number of primary branches per plant (0.05) and number of seeds per capsule (0.01) in their respective order of strength of correlation. This could be an indication for the selection program of Black Cumin to focus mainly on plant height and number of capsules per plant if the intension is to go for high yield. On the other hand, seed yield showed negative correlation with days to flower, days to maturity and biomass yield.
