The present investigations were conducted on sixteen genotypes of sprouting broccoli (Brassica oleracea var italica Plenck) in Randomized Complete Block Design in two environments, viz. rabi 2010-11 and rabi 2011-12. Character association analysis revealed that marketable yield/plant was significantly and positively correlated with terminal head weight/plant, harvest index, gross weight/plant, head size index, days to first harvest, leaf size with leaf stalk, plant frame and leaf size without leaf stalk which could be considered as the important selection criteria in the improvement of marketable yield. The results of path analysis revealed that the maximum positive direct effect on marketable yield/plant was exhibited by terminal head weight per plant followed by harvest index, gross weight per plant and head size index. This indicated that a selection procedure based on high terminal head weight/plant along with high harvest index, high gross weight/plant and high head size index may be effective in improving marketable yield.
