HETEROSIS FOR YIELD AND YIELD COMPONENTS IN PUMPKIN (CUCURBITA MOSCHATA DUCH. EX. POIR,)

Published on

An 8 x 8 half diallel cross of pumpkin was evaluated with parents for heterotic
manifestation of yeild and yield attributing characters. Heterosis to the extent of 17.8,
18.1, 70.0, 150.0, 68.7, 48.4 and 181.5 per cent over better parent was recorded for vine
length, number of primary branches, female flowers and fruits per plant, average fruit
weight, flesh thickness and yield per plant respectively. The crosses between high x
low performing (gca) parents exhibited greater hybrid vigour. Heterosis for yield wa
generally accompanied by heterosis for yield components. Ten promising crosses were
identified for developing high yielding. Fl hybrids/varieties of pumpkin with many
desirable traits.
