Diallel set involving ten parents (without reciprocals) and forty five hybrids of China aster (Callistephus chinensis [L.] Nees) were evaluated to analyse for the magnitude commercial heterosis for economic traits at the Department of Floriculture and Landscape Architecture, College of Horticulture, Mudigere. Appreciable heterosis was observed for all the characters and the performance of F1 hybrids was better than top parent. The overall maximum positive significant heterosis for yield in terms of number of flowers per plant was observed in Local Pink × Local White (18.27), Local Violet × AAC-1 (15.28) for cut flowers, weight of flowers per plant PG Violet × Arka Poornima for loose flower overcommercial heterosis. Negatively heterotic crosses like Local Pink × Local Violet (-14.69), for days to 50% flowering are important to exploit heterosis for earliness in China aster. The F1 hybrids Local Violet x AAC-1, Local Pink × Local White and PG Violet ×Arka Poornima with high yield potential has the potential for commercial cultivation after further evaluation
