Abstract

Heterosis over better parents was estimated in thirty crosses of China aster involving six lines viz., Matsumoto Pink, Matsumoto Red, Matsumoto Rose, Matsumoto Yellow, Matsumoto Scarlet and Matsumoto White and five testers viz., Phule Ganesh Violet, Phule Ganesh Purple, IIHRJ3-2, IIHRG13 and Local White during 2016-17 at ICAR-Indian Institute of Horticultural Research, Bengaluru during 2016-17. Results revealed that the cross L6 × T5 exhibited highest positive significant heterobeltiosis at 5% level of significance for plant height (33.85), flower stalk length (73.76), number of flowers per plant (101.18), weight of flowers per plant (47.90) and flower yield per hectare (47.91). The cross L1 x T3 exhibited maximum negative heterobeltiosis for days to first flowering (-47.41). L5 x T4 recorded the maximum positive heterobeltiosis (at 5%) for flower head diameter (26.44) and 100 flower weight (3.41).
