Linked genes with monogenic inheritance have been discovered for leaflet size (broad vs. narrow leaflets, Blf), leaflet shape (oval vs. acute Ol), stipule size (large vs. small Lst), pod size (large vs. small Lpd), and globe mutant (normal vs. globular plant canopy Glo). Broad leaflet was dominant over narrow leaflet, oval leaflet over acute, large stipule over small, large pod over small pod, and normal plant type over globe mutant. Linkage was established from the F2 segregation analysis of 2247 plants in six crosses for leaflet size, 2239 plants in six crosses for leaflet shape, 2140 plants in six crosses for stipule size, 2512 plants in six crosses for pod size, and 1127 plants in two crosses for globe plant type under field conditions, taking two characters at a time in all possible combinations when a pair of traits did not show independent assortment. Based on crossing over values the genes were arranged in the short linkage sequence Lst-Ol-Blf-Lpd-Glo. This short sequence of linked genes has been called linkage group III (LG III) of lentil.
