Abstract: P. sativum L. var. abyssinicum is a marginalized, economically important and endemic, cool - season legume - crop in Ethiopia. However, no genetic diversity study has been employed using molecular markers on this crop species sofar. Therefore, this study is aimed to investigate genetic diversity and population structure of P. sativum L.var abyssinicum collected from Southern Tigray and Northern Amhara regions of Ethiopia. Six ISSR (Inter simple sequence repeat) primers were used to...
Field survey was conducted from August to November 2016 and repeated from January to April 2017 to study population, distribution and damage by tomato leaf miner (TLM) (Tuta absoluta Meyrick 1977) in 156 farms in agroecological zones of Tanzania. A pheromone trap/farm was deployed in tomato or other Solanaceae’s crops for examining moth of T. absoluta stuck in each trap and to determine damage by TLM. Results indicated that TLM is present in 13 regions with the highest population in Souther...
