GENETIC VARIABILITY FOR YIELD, YIELD RELATED TRAITS AND REACTION TO LATE BLIGHT IN POTATO (Solanum tuberosum L.) GENOTYPES AT SINANA, SOUTH EASTERN ETHIOPIA

Abstract:

The highlands of Bale is known with potato production, but the productivity of the crop is low due to the growing of low yielding genotypes susceptible to late blight. This needs to develop varieties with high yield and resistant to late blight. Therefore, this study was conducted to evaluate 24 potato genotypes with the objective of assessing the nature and magnitude of variability for tuber yield, yield related and late blight resistance traits, and association of tuber yield with other traits. The experiment was laid out in randomized complete block design with three replications at Sinana Agricultural Research Center. The genotypes showed highly significant (P
