ekoko (

Pisum sativum var

abyssinicum

) is one of the most important food legumes grown in south Tigray and north

Wollo, northern Ethiopia. It is one among the most important food legumes in terms of price and protein content. It

grows alone and mixed with many cereal crops growing in north Ethiopia. This study was conducted with the objective of

selecting tolerant and relatively high yielding

P. sativum var. abyssinicum

collections under different salt (NaCl) concentrations

at laboratory conditions. The seeds of the six collections were obtained from four districts; two regional states of north Ethiopia

with different attitudinal ranges 1868 m a.s.l. being the lowest and 2457 m a.s.l. the highest. The six on farm vigorously growing

local collections, three from Ofla (T-001/08OF, T-002/08OF and, T-003/08OF), one from Sirinka (T-025/08Sr), one from

Emba-Alaje (TA-026/15E/A) and one from Endamohoni (T-023/15MW) were studied for salt stress tolerances in controlled

condition by priming in four salt treatment levels (5 dS/m, 7 dS/m, 9 dS/m and 15 dS/m). Distilled water (0 dS/m) was

used as control. 50 surface sterilized seeds per petri dish were sown for the four salt treatments and the control. Collections

T-001/08 from Ofla and T-023/08 from Endamohoni showed good growth performance at 5 dS/m. However, T-025/08Sr from

Sirinka and TA-026/15E/A from Emba-Alaje responded positively up to 7 dS/m. At higher salinity level (9 dS/m) growth

features decreased with increasing salinity stress. But, T-023/15MW, T-001/08OF, T-025/08Sr followed by TA-026/15E/A from

lower to the higher resistances, respectively, could withstand lower (5 dS/m) to medium (7 dS/m) concentrations of salinity as

compared to the other collections.
