Abstract
ABSTRACT
The present investigation entitled “Studies on emasculation and time of pollination in
hybrid seed production of bell pepper (Capsicum annuum L. var grossum Sendt.)” was carried
out using two varieties viz. Solan Bharpur and California Wonder. The experiment was laid out in
RCBD in the field and CRD in the laboratory with factorial analysis. The reciprocal cross was
attempted between Solan Bharpur and California Wonder (Solan Bharpur x California Wonder (C1)
and California Wonder x Solan Bharpur (C2)) by pollinating them at different times viz. pollination
immediately after morning emasculation (P1), pollination immediately after evening emasculation
(P2), pollination 12 hours after evening emasculation (P3), pollination 18 hours after evening
emasculation (P4) and pollination 24 hours after evening emasculation (P5). Here the effect of
different times of pollination, two crosses and their interaction was studied on various growth and
seed quality parameters. The observations in field were recorded on days from pollination to fruit set,
days from fruit set to ripe fruit maturity, ripe fruit weight (g), number of seeds per crossed fruit, seed
yield (g/plant) and seed yield (kg/ha). While the observations recorded in laboratory were 1000 seed
weight (g), germination per cent, seedling length (cm), seedling dry weight (mg), seed vigour index-I
and seed vigour index-II. ANOVA showed significant differences among the treatment combinations
for all the characters studied. The treatment combination C2P5 (California Wonder x Solan Bharpur
pollinated 24 hours after evening emasculation) was found significantly superior over all other
treatments in terms of growth, seed yield and seed quality characters. The individual effect of
different times of pollination indicated that treatment P5 (pollination 24 hours after evening
emasculation) was significantly better by showing maximum values for growth, seed yield and seed
quality parameters. In case of crosses, C2 (California Wonder x Solan Bharpur) was found
significantly superior for getting higher yields of quality bell pepper seeds.
