F ield pea (Pisum sativum L.) is a self-pollinated diploid (2n=14) annual cool-sseason pulse crop. It is also a major food legume with a valuable and cheap source of protein having essential amino ac-ids that have high nutritional value for resource-poor households (Nawab, 2008;Getachew, 2019). It is widely grown in the cooler temperate zones and in the highlands of tropical regions of the world. The crop is cultivated in a wide range of soil types from light sandy loam to heavy clays but does not toler-Abstract | Field pea (Pisum sativum L.) is one of the leguminous crops that is rich in protein and essential amino acids. A field experiment was conducted during the 2019 cropping season consisting of eight (Bursa, Burkitu, Adi, Herena, Hortu, Letu, T/shaman, and Weyib) improved field pea varietiesand one local variety at west Showa zone Oromia region to identify high yielding varieties. The experiment was carried out using a randomized complete block design with two replications at Babich, Goda Hora, Chelia Rafiso Alenga, EjersaLafo, and Goromti locations. Data on yield and yield-related traits such as harvest index, above-ground biomass, number of seed per pods, and hundred seed weights were recorded. Analysis of variance combined over five locations manifested significant differences among varieties, environment, environment, and varieties interaction for grain yield and other yield-related traits. The combined mean of grain yield of varieties indicated that Bursa (3.03 t/ha), Adi (2.84t/ha) and Weyib (2.83 t/ha) varieties had the highest grain yield advantage over the other tested varieties without significant difference among the order, whereas Burkitu (2.3 t/ha), Herena (2.35 t/ha) and Hortu (2.39 t/ha) varieties manifested low grain yield. Generally, it is better if the work is repeated in the future for more justification since it was only one season experiment and the grain yield stability test of the higher yield varieties is advisable before recommending the varieties for largescale production at the studied area.

This research was conducted to assess genetic distance, extent, and pattern of diversity among sesame accessions. A total of 64 sesame Accessions were evaluated in an 8 x 8 lattice design with two replications in 2021 at Werer Agricultural Research Center. Analysis of variance revealed that there was a statistically significant difference among the accessions for all traits except for 50% days to emergence and the number of seeds per pod. Principal components analysis showed the first five PCAs viz. PC1 (21.9%), PC2 (11.00%), PC3 (15.6%), PC4 (18.3%), and PC5 (9.5) with a total contribution of 76.3% variation. The dendrogram was constructed using the Unweighted Pair-group Method with Arithmetic Means to separate Accessions into five distinct clusters. Sesame accessions with high seed yield and high mean values for other desirable traits were grouped into Cluster I and Cluster V. Cluster IV and Cluster V had the highest inter-cluster distance. Accession in Cluster V (Acc.241297) could be crossed with other clusters to come up with promising segregation for further improvement programs.
