 Origin Kobe university→Hokkaido University, Laboratory of Experimental Animal Science(Hok) 1975→Hokkaido University, Center for Experimental Plants & Animals(Hok) 1982, F19. Long Evans Agouti derived originally from an outbred Long Evans stock at Hokkaido University and selected for agouti coat colour (though Long Evans stock is usually fixed for non-agouti, hooded genes).  
 Strain Characteristics The LEA rat was established from a Long-Evans rat closed colony as the control strain of the LEC rat, which is reported to exhibit several mutant phenotypes such as hepatic disorder (<i>hts</i>), blockage of the T cell differentiation (<i>thid</i>) and X-ray hypersensitivity (<i>xhs1</i> and <i>xhs2</i>). But LEA rat is hypersensitive to X-rays to a similar degree as the LEC rat. 
 Breeding Conditions Good breeding performance. Sib-mating.
