Plant sample from Erucastrum abyssinicum
E. abyssinicum (A. Rich.) O.E. Schulz is adapted to extremely low temperatures of Ethiopian highlands (> 3000m) and its phenotypic evaluation has shown it to be an excellent source of resistance to cold, heat and drought stresses. Wide hybridization between E. abyssinicum and B.juncea have allowed the development of alien introgression lines which vary for resistance to these stresses
