Abstract
The study was conducted at Demo exp. farm, Fac. Agric.,
Fayoum Univ., during 12/2013 and 13/2014, on 36 genotypes of
hybrid origin together with 4 parental cultvaries to evaluate growth
and reproductive traits. Exp. design was RCBD with three
replications, where grains were sown, on 23th and 19th November, in
the two seasons, in rows of 3.5m long and 25 cm apart and 5cm
between plants. The culture practices recommended for growing
wheat were followed. During each season, two vegetative samples (5
plants for each) were randomly taken from inner center rows plot-1 at
105 and 130 days ages to measure the growth traits. At harvest, yield
and its attributes were evaluated. The results revealed significant
differences among genotypes for both growth (in the two samples)
and yielding traits in the two seasons. Growth trait performance at
young age showed that G.17, G.3 in 1st season and G.4, G.33 and
G34 in 2nd season were superior for some traits (for each). In the 2nd
sample, G.35, G.34, G.17 and G.12 in both seasons and G.21 in 1st
season were of advantage of some growth traits. The performance of
yielding traits showed that G.3, G.17, G.24, G.30, G.32 and G.35 in
both seasons and G.16 in 1st one were elite for some traits for each.
Compared to other genotypes and checking CVS. Variability results
represented by Vp, Vg, Ve, PCV and GCV indicated great range of
variability among genotypes in regard to growth and yielding traits.
Mostly, Vp of growth traits at the two ages were higher than the
corresponding Vg. PCV ranged from 10.13 and 10.42 for plant height
to 44.47 and 59.60 for extrusion length at young age in the two
season, respectively. In the 2nd sample, PCV ranged from 7.55 and
7.62 for spike length and 25.18 for total leaf area plant-1 in 1st season
and 25.57 for extrusion length in 2nd one. The corresponding GCV
ranged from 9.95 and 10.33 for plant height to 44.29 and 95.30 for
extrusion length at young age in both seasons. At late age, GCV
ranged from 7.41 and 7.39 for spike length to 24.85 for total leaf area
plant-1 in 1st season and 28.42 for extrusion length in 2nd season.
Regarding yielding trait, PCV ranged from 4.19 and 4.31 for days to
physiological maturity in both seasons to 23.45 for grain yield/fed in
1st season and 34.54 for straw yield in 2nd season. GCV ranged from
4.11 and 4.25 for days to physiological maturity in both seasons to
21.81 for grain yield/fed in 1st season and 32.38 for straw yield in 2nd
season. Growth and yielding trait exhibited high broad sense
heritability as well as acceptable genetic advance percent from
means, in both seasons.
