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.

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 fromOfla 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
7dS/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.
Biography
Berhane Gebreslassie has his expertise in plant physiology and particularly of the legume crops physiology in improving the agronomic performances and yield
increment in this climatic change scenario era. His experience both in Academic and research works on saline areas of the tropics and sub-tropics creates
new pathways for improving legume crops production and productivity. He started is study on salt priming particularly of sodium chloride ( NaCl) at different
concentration for optimization of salt stress tolerance that trigger rapid biochemical and metabolic activities to tolerate the stress thereby increasing their growth
starting from germination of Lathyrus sativus L. and Pisum sativum var. abyssinicum. This approach is responsive to all stakeholders and has a different way of
focusing on crops challenged by many factors in the nowadays climate changed world. Thus, take measures that enable them to tolerate and produce good yields
requires a scientific research for better solution and recommendation.
