We wish to test if participatory approaches and modern molecular marker techniques can be effectively combined. To do this we have integrated participatory plant breeding (PPB) with marker-assisted selection (MAS). The PPB has been carried out on six bulks selected with molecular markers via modified single large-scale MAS (SLS-MAS). The bulks were derived from the second backcross generation between Kalinga III and Azucena where Kalinga III was the recurrent parent (See Part I: Molecular Breeding Strategy, this volume). Four of the bulks had been selected to contain a quantitative trait locus (QTL) for root growth. One bulk was a selected subset of those with root QTLs which had also inherited a marker for aroma. A control bulk was selected from the same generation, which contained none of the targets and was used to test the effect of the target root QTL. Bulks were given to farmers in three states of Eastern India for evaluation over two seasons of collaborative PPB. The same bulks were also tested onstation through consultative PPB, with off-season seed multiplication.
