Results were obtained with composite interval mapping by using qtl cartographer. S, short arm; L, long arm; C, centromere region. 

^*The likelihood ratio can be converted to the more familiar logarithm of odds score by dividing by 4.6052. 

^†Percent phenotypic variance explained at nearest RFLP marker by using the SAS GLM procedure.
