Heterobeltiosis in African marigold (Tagetes erecta L.)

Published on

A line x tester crossing programme was taken up with
three male sterile lines viz., mS7, mss and mS12 and a
set of 11 diverse pollinators such as selections 7, 8, 14,
19, 21, 22, 27, 28, 29, 31 and 56 used as testers. The
hybrids (33 F1S) along with parents were evaluated during
1995-96 (winter) and 1996 (summer) in randomized block
design with three replications. Detailed observations on
12 and 10 characters during winter and summer
respectively showed that F,s were much better than the
mean performance of the parents during both the seasons.
Appreciable heterosis was observed in all the characters
except in two.
