the standard heterotic effects, the number of crosses
having desirable heterosis was more with number of
fruits per plant, seed weight, plant height, days to 50%
flowering, number of seeds per fruit, pericarp weight
and dry fruit yield per plant. Yield contributing
characters such as number of primary branches per
plant (33.33%), number of fruits per plant (83.29%)
fruit weight (21.70%), Fruit length (35.54%) and
pericarp weight (26.51%) exhibited significantly high
value of useful heterosis. Similar findings were also
reported by Gvozdenovic et al. (1995).
For days to 50% flowering significant negative
heterosis was exhibited to an extent of –12.99, -11.24
and –13.48 per cent by the crosses Puri red×Lokur
local, 124×Byadagi kaddi and Puri red×Lokur local
over mid-parent, better parent and standard check
respectively. While, same was observed up to tune of
–23.87, -22.81 and –21.49 for stalk length, and
–51.11 per cent for seed weight over mid-parent,
better parent and standard check respectively.
Negative heterosis was also reported by Singh and
Singh (1976), Dikii and Anikeenko (1981) and
Gopalkrishnan et al. (1985).
For plant height mid-parent, better parent and standard
heterosis was recorded to an extent of 18.19, 15.94
and 25.38 per cent by the crosses 124×KDC-1 and
GPC-82×Singanahalli local respectively. Previously
Ishfaq and Mohammed (1997) reported positive
heterosis for plant height.
A perusal of the top heterotic crosses revealed that
none of the crosses was consistent for all the traits.
Out of 72 crosses studied 30 showed significant
