Registration of Mieso, a Newly Released Field Pea (<i>Pisum sativum</i>) Varieties for Highlands of Bale, Southeast Ethiopia

Abstract

Field pea (<i>Pisum sativum</i> L.) variety named Mieso with the pedigree designation of Acc 32003-2 has been officially released by Sinana Agricultural Research Center in 2021. The variety is best adapted to altitudes ranging between 2300 to 2600 meters above sea level in the country. Mieso variety evaluated along sixteen Field pea genotypes including the standard check “Harena and T/Shenene” under a regional variety trial for three years (2016 to 2018) at Sinana, Sinja and Agarfa districts. Promising genotype, “ACC32003-2” were selected and promoted to variety verification trail with the standard check during the 2020/21 cropping season. Finally, the National Variety Release Technical Committee decided “ACC32003-2” genotype for release. This Field pea variety showed superior performance particularly in terms of productivity and resistance/ tolerance level to disease across the years and locations. The released variety out-yielded the other tested Field pea genotypes on both research plots and farmers’ fields. Based on most stability parameters, Mieso showed relatively better grain yield performance (3570kg/ha) and stability across a range of environments and years than the standard checks (Harena and Tulu Shenene) and could be cultivated across a number of locations in the highlands of Bale and other similar agro-ecologies for increasing productivity of the crop.
