Abstract:
An experiment to evaluate
comparative performance of various
sunflower hybrids for yield and its related
attributes was conducted at the Agronomic
Research Area, University of Agriculture,
Faisalabad, Pakistan, during autumn 2008.
Twelve sunflower hybrids, i.e. G-101 (H1),
DK-4040 (H2), SF-187 (H3), S-278 (H4),
Hysun-33 (H5), FH-37 (H6), Ausigold-61
(H7), Ausigold-62 (H8), FSS-50 (H9), NX-
00989 (H10), NX-00997 (H11) and XIYU-12
(H12) were included in the trail. The
experiment was laid out in randomized
complete block design (RCBD), having
three replicates with plot size of 5m x 3m.
Statistical analysis of the data showed
significant differences for all the
parameters. It was observed that Hysun-33
showed greater plant height (148.47 cm)
and achene per head (682.70) than all other
hybrids, however in case of yield (3891.0 kg
ha-1) and other related traits such as number
of plants m-2, leaf area index, head diameter
and 1000-achene weight SF-187 displayed
better performance by recording values
(6.87), (4.33), (18.62) and (49.11g),
respectively, following Hysun-33 for most
of the traits. From the results of experiment
it can be concluded that the hybrids SF-187
and Hysun-33 showed high productivity and
are best adapted to the climatic conditions
of Faisalabad.
