| dc.description.abstract | The present investigation was carried out to obtain information on the response of parental lines to the environment in different provenances with respect to flowering behaviour of male and female parents and their synchronization, seed yield and quality parameters in newly released sunflower hybrid KBSH-78 (CMS 1103A x RHA92) during rabi (crop sown in the month of December 2021). The study indicated that sowing of parental lines at different locations had no significant effect either on growth, seed yield and quality parameters. However, the seed crop of Bagepalli recorded higher values for plant height (105.60 cm), days to 50 per cent flowering (62.55), days to maturity (97.84), seed yield / plant (18.93 g), 100 seed weight (4.40 g), seed yield /ha (1051.66 kg), germination (90.50 %). The staggered sowing was found to be non-significant for all growth, yield and quality parameters in both male and female parents, but sowing of male parent by four days late to female parent (S3) resulted in better synchronized flowering between male and female parents which lead to enhanced seed set (84.58%). In female parent, sulphur spray recorded higher values for capitulum diameter (13.18 cm), seed yield per plant (22.55 g), number of filled seeds (311.01), 100 seed weight (6.88 g), seed setting (84.58%), seed yield (1252.92 kg/ha) and quality parameters like germination (91.78 %), shoot length (18.25 cm), root length (20.68 cm), seedling dry weight (0.37 g), mean seedling length (38.16 cm), SV-I (3503) and SV-II (34). The germination was maximum (99.70%) at 50 DAH in Ranebennur followed by Bagepalli (99.60%) and Bengaluru (99.25%) although no germination was recorded in freshly harvested seeds. | en_US |
