Abstract
Sunflower originated from Latin America, has become the major oil crop world wide. It is also
an important edible oil crop in Pakistan. Major research has been conducted regarding genetic
variance in sunflower. Sunflower hybrids are a focal point in contemporary research. The main
aim of conducting this study was to evaluate the performance of selected hybrids for different
parameters regarding yield and related traits Desired study was conducted at Agriculture
Research Institute (ARI) Quetta during the period of April to August 2009.. Data was collected
from ten hybrids of diverse origin; hybrids were US-666, FSS-64, Sierra, Barracuda, Roshan,
FH-385, NK-S-278, VDH-487, Blazer-CL, Ausigold-61. Eight traits were observed for these
hybrids, including days to flower initiation and completion, days to maturity, head diameter, plant
height, 100 seed weight, number of leaves per plant and oil contents. Correlation along with
heritability and genetic advance was determined for selected traits. On the basis of over all mean
performance hybrid Blazer-CL was found best among all the selected hybrids. Using Anova
significant difference was found for all the traits observed. High broad sense heritability and high
genetic advance was recorded for most of the studied traits. Mostly positive and significant
correlation was found among the observed traits.
