Abstract:
This study was .conducted at the demonstration from of the
collage of agriculture studies of Sudan University of Science
and Technology. During the period from November to
February
2011to
evaluated
four
cultivars
of
sunflower
.((Helianthus auunns L
The experiment was carried out in Randomized Completed
.Block Design with four replications
In order to study the range of genetic variability, heritability
genetic coefficient with four replications. Search growth and
.yield character were measured in chorded
In order to study the range of genetic variability, heritability
.genetic coefficient of variation and genetic advance
The data revalued (8) characters were collected. Significant
differences and non significant in growth and yield trait
among the four cultivars. Except plant height, number of
leaves per plant, leaf efficiency, steam diameters mature
.seed weight and yield kg/ha
The highest of (G.C.V) was recorded for number of leaves per
plant (33.78%). Whereas the lowest of G.C.V)was the stem
diameters (2.26%) the highest moderate heritability (h2
76% ) were scored for 100 seeds weight , leave efficiency ,
while the lowest estimated (h2 40%)was attained for plant
height, number of leaves per plant, Stander disc. Mature seed
