“…The genotype exhibited significant heterogeneity in location and molecular weight, which ranged from 300 to 800 bp. Figure (3) shows that bundles with a molecular weight of 650 bp appeared in the majority of the genotypes, with genotype 5 having the fewest bundles. Genotypes 2 and 3 were distinguished by the absence of proliferative bundles.…”

The experiment was carried out in 2022 in the biotechnology laboratories of the Agricultural Research Department - Ministry of Science and Technology with the aim of studying the molecular variations between 5 barley cultivars (Samir, Aksad, Amal, Buraq and IPA 265) in order to estimate the genetic divergence and determine the degree of genetic kinship between them. In order to be used for the production of hybrids, the RAPD technology was used, based on PCR technology and 12 primers. A 20 with a molecular weight that ranged between 150 - 2000 bp The total number and %age of differentiated cuts were 92 and 80% respectively The starter H 9 gave the highest %age of differentiated cuts amounting to 90.9% while the primer A 20 showed the lowest %age of differentiated cuts amounting to 57.1% The highest primers efficiency was 11.3% in the A15 primer and the highest differentiating ability was 11.9% in the H9 and A15 primers, and based on the data of the molecular index and genetic similarity using the UPGMA method in the linkage scheme, the two were separated. Varieties in two main groups, one group containing S5 (class Aba 265), and the second group containing the rest of the varieties according to the nearest neighbor method. The lowest genetic similarity and the degree of genetic kinship (the highest genetic divergence) between the cultivars was 0.61 between the two cultivars S1 x S5 (IPA 265 x Samir) as well as 0.62 between the two cultivars S2 x S5 (Aksad x IPA 265) and the highest genetic similarity (ie, the lowest genetic dimension)) It was between the two categories S3 x S4 (Amal x Buraq) and it amounted to 0.86. The results indicated that RAPD parameters are highly efficient in diagnosing purity and genetic divergence between barley genotypes.

“…The statistical analysis results of table (3) showed significant differences among the level concentrations of salicylic acid and genotypes (parents and their cooperative hybrids) for both seasons and the co-interference of both study factors in leaf area traits for seasons spring and fall. Inbred line 2 plants have given the highest average value of this trait as 4967cm 2 , which has not differed significantly from parents 3 and 4, while parent 1 made the lowest trait average value of 4467cm 2 for the spring season.…”

An experiment was conducted at Al- Hamidhia Research Fields, Faculty of Agriculture / Al- Anbar University in North Ramadi city to study the levels of salicylic acid 0, 200 and 400 mg. L-1 and fifteen genotypes (5 inbred lines + 10 hybrids) of maize. A randomized complete block design was used in a slit table arrangement; thus, the main treatments are for salicylic spray, and the secondary tables are for genotypes (inbred lines and hybrids). Three replications were made to produce two-purpose hybrids (grain and forage yield) by introducing some inbred lines and maize hybrids grown by the semi-co-breeding program. Results have shown the dominance of hybrid BK104× Zm6 giving the highest product of leaves staying green that reached 222.1g and 8.9 leaves, successively in the spring season. In comparison, the hybrid Inb-27× BK104 has dominated in the fall season, giving yield and leaves stay green as 247.01g and 9.45 leaves successively. The reason for these hybrids dominance returned to their dominance with grains numbered a row, grain weight and dominance of salicylic acid concentration 400 mg.L-1 for both seasons, giving the highest yield as 179.10 and 177.33g and didn't differ significantly from salicylic acid concentration 200 mg.L-1. The interaction treatments were significant for all the traits, except the trait of 300 grains weight for the spring season. So, we recommend using 200 mg.L-1 concentration of salicylic acid and the dominant hybrids in yield for both seasons. Keywords: AS, Inbred lines, Diallel crops, plant growth regulator, grains yield, grain weight.

Selection by the honeycomb is used to obtain high-yielding genotypes from the sunflower, The selection is carried out using several genotypes, as they are grown for more than one season, with a distance of 1.3 m between furrows and 1.5 m between the plants. The selection depends on the area of the sunflower disk. The selected seeds are randomly planted and pollinated in the third season. The seeds resulting from random pollination are sown in a comparative experiment with the original populations and evaluate them at different densities. Selection criteria are based high yield. In addition to studying the molecular indicators of the selected and original genotypes to know the genetic and molecular distance between them in order to choose the appropriate breeding method. Honeycomb selection is expected to improve plants performance for a number of genetic, phenotypic and physiological traits due to the additive gene. Therefore, we suggest adopting the honeycomb selection program to select active strains, whether by using improved varieties or strains to obtain new hybrids that are better than what is produced today through known breeding methods.
