Abstract: 

The research was carried out in Damsarkho district of Lattakia Governorate during the two agricultural seasons 2021 and 2022, according to the randomized complete block design (RCBD) and with three replications, for five genotypes of wheat (Triticum aestivum L.) (Sham4, Sham6, Sham8, Sham10, Research6), which we obtained from the Seed Multiplication Corporation and some agricultural pharmacies in Lattakia (these types are characterized by their suitability to the local environmental conditions, their resistance to agricultural pests and the variation in their quantitative and qualitative productivity), to study some genetic indicators of the most important morphological and productive traits (number of total shoots, plant height, spike length, head length, number of Fertile spikelets, the number of total spikelets, the number of grains in a spike, the weight of grains in a spike, the weight of 1000 grains, and the grain yield per plant). With the aim of selecting the best ones and benefiting from them in the programs of breeding this crop and improving it to develop models of soft wheat for the desired characteristics and adapted to the local environment. The studied genotypes of soft wheat differed significantly in all studied traits, and the results showed the presence of genetic variations and differences in the degrees of heritability and genetic progression, in addition to differences in the values of the genetic, phenotypic and environmental correlation coefficients for all studied traits in soft wheat. The studies also demonstrated the possibility of establishing different selective indices for the important traits studied through the positive genetic correlations between the studied traits. The current study indicated that the priority given to traits such as the number of grains per spike, weight of 1000 grains, length of the spike, the number of total spikelets per spike, and plant height during the selection process to improve the crop due to its high heritability rates associated with good genetic progress.

Keywords: wheat, degree of heritability, genetic progression, correlation coefficient.

Abstract: 

 The research was carried out during the years (2020 and 2021) in the nursery of the College of Agriculture at Al-Furat University, to study the effect of foliar spraying with urea on pear (Pyrus communis L.) seedlings with three concentrations (5-10-15g/L), and cytokinin acid at a concentration of 100 mg / L and iron chelate at a concentration of 50 mg/L in improving the indicators of vegetative and root growth. The results showed that spraying with cytokinin acid or iron chelate alone or in combination with urea improved the vegetative and root growth indicators of the seedlings compared to the control. The results of the research showed that the treatment with cytokinin acid or iron chelate affected growth indicators. The treatment of spraying iron chelate gave the highest significant values of the length of the seedlings (79.10) cm, diameter (5.30 mm), the number of branches (8.5), the number of leaves (220) the leaf area (787 cm2), the content of leaves of chlorophyll (43.1 mg / g), the fresh vegetative weight (60.40 g) and dry (31.7 g) with significant differences compared with the control. The results also showed that spraying with cytokinin acid or iron chelate with urea increased the growth indicators by significant differences compared with the control. The treatment of spraying iron chelate and Urea at a concentration of 5g/L gave the highest values for the average number of leaves (206), leaf content of chlorophyll (37.7mg/g), and fresh shoot weight (53.89g) compared with the control. and it was also noted that the treatment with cytokinin acid and urea at a concentration of 10 g/L, it gave the highest averages for the length of the seedlings (75.28 cm), diameter (6.16 mm), leaf area (989 cm2), wet root weight (40.3 g) and dry root weight (19.9 g) compared to the control, while the treatment with cytokinin acid and urea at a concentration of 15g/L gave the highest averages for the number of branches (11.4) compared with the control.
