Thirteen monogenic morphological marker traits of lentil were analysed for
their joint inheritance in 25 crosses. Only three traits showed linkage: Er
t (for spreading-erect growth habit), Gs (for brown-green stem) and BI (for
brown-green leaf). The recombination frequency between BI and Gs was 14%,
between BI and Ert 34%, and between Gs and Ert 38%. Thus, the gene Bl is lo
cated between Ert and Gs.
