The present investigation was undertaken to obtain information on heterosis for various morphological, yield and quality attributes. The experiment comprised of ten diverse parents of broccoli, along with their 45 F1 crosses (excluding reciprocals) which were evaluated in Randomized block design, with three replications during 2008 and 2009. Heterosis (percent) estimates over better parent and standard parent (Green Head) were worked out to have an over view for their future use in exploitation of heterosis and development of improved populations and varieties. In the present study, from among forty five crosses there was no cross combination which exhibited significant standard heterosis for characters like plant height, head length, leaf number, days to central head initiation, days to central head harvest and total carotenoides. However 12 and 19 crosses for plant spread, 8 and 10 crosses for head diameter, 10 and 24 crosses for leaf area, 6 and 15 crosses for lateral head number, 27 and 7 crosses for main head yield, 13 and 19 crosses for lateral head yield, 15 and 6 crosses for total head yield, 8 and 27 crosses for dry matter content and 3 crosses each for ascorbic acid showed significant heterobeltiosis and standard heterosis. From among 45 crosses, on the basis Standard Heterosis, crosses BI-7042-24 x SH-BR-4, Calaberese Amule x SH-BR-4, SH-BR-1X SH-BR-4, SH-BR-2 X Palam Vichitra and Palam Samridhi x Green Head were found superior for total head yield and yield related traits. While among cross combinations the crosses like SH-BR-1 X SH-BR-3, BI-7042-24 X Palam Vichitra were best combinations in respect of quality parameters and these hybrid combinations therefore have great potential for commercial exploitation.
