The self-incompatibility problem appeared in the Khodeiry variety widely grown In
Lattakia. When this phenomenon was studied on the Khodeiry variety in two areas (Jabla
and Boqa), the results showed that this variety is self-sterile, i.e. it is not
able to pollinate
itself or the flowers of other trees of the same variety, and its fruit is very small and do not
contain seeds. The results also showed that the flower abortion percentage in the Khodeiry
variety is due to the genetic factor which varies depending on the variety. The study
investigated the self-compatibility in some olive varieties in order to use them as
pollinizers for the Khodeiry variety with the result that the Gellet, Soufrawy and Sourany
varieties are particularly compatible and have a high compatibility with the Khodeiry
variety. Based on these results, it is recommended that pollinated varieties are grown
between olive orchards to improve fruit and to increase its production.
A field trail was conducted at Jeleen Research Station, Dara,a governorate,
Syria, during two consecutive growing seasons (2010/ 2011-2011/ 2012), in
order to evaluate the role of some cultural practices in improving nitrogen use
efficiency and gr
ains quality characteristics of four wheat varieties (Acsad1105,
Acsad1229, Acsad885 and Acsad901). The experiment was laid according to
randomized complete block design-split, with three replicates. Leaf area index,
grain starch content and grain yield were significantly higher during the first
growing season, in the wheat variety (Acsad901), for the first planting date, and
nitrogen rate (200 Kg N. ha1-), when nitrogen fertilizer was added in two splits
(1.25, 68.60 %, 1051 g. m-2).
In this
search we characterized 8 double purposes olive varieties (Mawi
Istanbuli, Khilkhali Khishen, Dan, Mniekri, Doaibli, Khilkhali
Saghir, Karamani Modabal, Sourani), which cultivated in ACSAD
Gene bank in Gellin by ISSR molecular markers to
determine the
relationship between these varieties, we noticed that these varieties
are so close to each others depending on quantitive traits, which
ranged from 60% and 85%, it was noticed that Mneikri was apart
from the other varieties in its traits, polymorphic rate was 92.94%.
The research was carried out at Tal Hedya Research Center in Aleppo, General
Commission for Agriculture Scientific Research (GCSAR), Syria, during 2011
and 2012 seasons. Seven genotypes of cotton were used, and complete diallel
hybridization was m
ade to study general and specific combining ability of some
productivity traits (sympodial branch number, actual boll number and seed cotton
yield). General combining ability (GCA) indicated that the parental genotype
Cherpan432 had a high significant GCA for sympodial branch number and actual
boll number, but the parents Aleppo118 and Deir El-Zour22 had the high GCA for
seed cotton yield. This is a clear indication that these parental genotypes had the
largest number of additive genes action, which plays important role in the inheritance
of the above-mentioned traits. The estimation of SCA values showed favorite and
high significant values in many hybrids resulted from parents, which had highly
significant GCA, which means that the gene action type is (additive x additive), and
this refers that these hybrids possessing the largest number of additive genes. High
heritability broad sense refers to importance of genetic variance in the inheritance of
all characters, but heritability in narrow sense values were low in general, indicating
the importance of dominance and epistasis genes in the inheritance. According to
this result it is recommended to follow the cross method for improvement of the
studied traits.
The current research aimed at identifying the effect of marriage
of relatives in the personal social consensus among a sample
of students of Al-Baath University.
The study sample reached (320) students of Al-Baath
University in Homs (160) of the
people in the case of marriage
of relatives and (160) of the people in the case of marriage of
the far away.
In this study, the researcher used the measure of personal
social compatibility .
