Description A field experiment was conducted at Main Agricultural Research Station, College of
Agriculture, Dharwad during kharif 2005-06 to study the correlation studies between seed,
seedling, growth and yield characters on yield of sunflower hybrids. The experiment
consisted of eight sunflower hybrids and was laid out in randomized block design with three
replications. Among the hybrids studied, KBSH-44 hybrid recorded more seed density (1.0
g/cc) hundred seed weight (5.86 g), kernel weight (76.47%) and kernel to hull ratio (3.3).
Germination percentage (88.3), rate of germination (29.0), root length (14.5 cm), shoot length
(15.9 cm), seedling vigour index (2687), seedling dry weight (123.0 mg), plant height (180.0
cm), number of leaves (23.6), leaf dry matter (34.9g), stem dry matter (45.8 g), total dry
matter (80.7 g), head dry matter (30 g) head diameter (16.8 cm), number of seeds per head
(1345) number of filled seeds per head (1196), seed yield per plant (74.5 g) and seed yield
per hectare (17.16 q). Among the hybrids the characters like seed, seedling, growth and yield
recorded highly significant positive correlation with respect to hundred seed weight (0.749),
seed density (0.831), kernel to hull ratio (0.592), root length (0.592), shoot length (0.810),
seedling vigour index (0.716), plant height (0.538), number of leaves (0.718) at 60 DAS, leaf
dry matter (0.549), stem dry matter (0.748), total dry matter (0.758), head diameter (0.804),
number of seeds per head (0.589), number of filled seeds per head (0.645), Seed filling
percentage (0.615) and hundred seed weight (0.546) with yield.
