A line × tester set of 13 parents involving 3 male sterile lines and 10 pollen parents of African marigold (Tagetes erecta L.) and their 30 hybrids were analyzed for heterosis with respect to various growth and flowering traits. The hybrids MSC3 × JS3 and MSC1 × JS5 exhibited maximum heterosis over mid parent and better parent respectively, for number of branches per plant, whereas MSC1 × JS1 showed highest heterosis over both mid parent and better parent for plant height. The maximum heterosis value for early flowering were observed in the hybrid, MSC1 × JS2 over better, mid and standard parent respectively, however the hybrid MSC2 × JS3 exhibited maximum heterosis over both mid parent and better parent for traits, duration of flowering and plant spread; and MSC1 × AAUM3 and MSC3 × Pusa Narangi Gainda reported highest values of heterosis over standard parent for duration of flowering. The hybrids, MSC3 × Pusa Basanti Gainda showed highest value of average heterosis and MSC3 × Pusa Narangi Gainda exhibited maximum heterosis over better parent and standard parent, respectively for number of flowers per plant. For flower size, the maximum heterosis over mid, better and standard parent were observed in hybrids, MSC3 × JS2, MSC2 × AAUM4 and MSC3 × AAUM4 respectively. The hybrids, MSC1 × Pusa Basanti Gainda showed highest value of average heterosis and MSC1 × AAUM5 exhibited maximum heterosis over better parent and standard parent, respectively for flower yield per plant. The hybrids, MSC3 × AAUM5, MSC1 × AAUM5 and MSC3 × AAUM3 exhibited highest heterosis for vase life of flowers over mid parent, better parent and standard parent, respectively.
