The aim of the research was to study the nature of variability of the main quantitative traits in hybrid populations of the second generation Phaseolus vulgaris L. within the framework of the task 13.00.01.28. F “To study the nature of the inheritance of quantitative traits in hybrids of create a starting material with improved flavoring properties.As a result of the studies carried out, it was found that regardless of the duration of the growing season of the parent components of the crossing, in the hybrid populations of the second generation, the limits of variability for this indicator went beyond the limits of the variability of the parent forms. The average values of the duration of the growing season in hybrids were intermediate between the indicators of the corresponding parent forms. The coefficients of variation in the parent forms were insignificant (1.1 – 1.4%); in hybrid populations they were low – from 4.9% (Line 744-14 / Ukrainka) to 9.2% (Line 741-14 / Suita).In terms of plant height, the limits of variability of hybrid offspring F2 went beyond the limits of variability of the parent components. The average values of the trait in hybrid populations significantly exceeded the corresponding indicators of the parent forms. The degree of variability in plant height of hybrid populations was significant in the combination Line 872-14 / Podolyanka-1 (the parent components differ in the type of plant growth) and was equal to 20.6% versus 3.5% and 4.9% for the corresponding parent forms. In other hybrid populations, the coefficient of variation was average (Ukrainka / Suita-16.5%; Line 741-14 / Suita – 13.5%; Line 744-14 / Ukrainka -10.1%) The degree of variability of the corresponding parental forms was in the range from 2.8% to 3.1%.The widest range of variability was observed according to the characteristics of the mass of seeds from the plant, the number of seeds from the plant, the number of beans from the plant. The degree of variability of the seed mass from the plant in hybrid populations ranged from 30.3% to 39.1% (in the parent forms from 9.1% to 21.7%); the number of seeds from the plant from 22.3% to 40.7% (in the parent forms from 9.8% to 20.1%); the number of beans from the plant from 28.1% to 38.3% (in the parent forms from 4.7% to 16.2%). The degree of variation of the studied traits in hybrid populations was 2–3 times higher than in the parent forms.By the weight of 100 seeds in the offspring of the second generation, the range of variation was much wider than this indicator in the parent forms. The degree of variability on this trait was average for hybrid populations (from 10.6% to 13.4%), and insignificant for parental forms (from 3.7% to 6.6%).It is possible that the most valuable in terms of breeding may be the hybrid combination Line 872-14/Podolyanka, from the widest range of variability in the studied traits in the second generation population.

Доведено, що ступінь фенотипового домінування у гібридів F1 може варіювати від hp > +1 до hp < -1 залежно від компонентів схрещування. Встановлено, що переважна більшість гібридів F1 тривалість веґетаційного періоду та його міжфазних періодів успадковують за типами позитивного наддомінування та позитивним домінуванням. Успадкування висоти рослин відбувається за типами позитивного домінування, проміжного успадкування та за типом негативного домінування. Характер успадкування висоти прикріплення нижнього ярусу бобів у значній мірі визначається поєднанням батьківських компонентів. Так, у першому поколінні у гібридних комбінаціях спостерігається явище наддомінування. За ознаками урожайності та її елементів (урожайність насіння, маса насіння з рослини, маса 1000 насінин, кількість бобів на рослині, кількість насінин із рослини, кількість насінин у бобі) у всіх без виключення гібридів першого покоління спостерігався гетерозис. It was demonstrated that the degree of phenotypic predominance in F1 hybrids can vary from hp to hp < +1 > -1 depending on mating components. The vast majority of the F1 hybrids inherit the length of the growing season and its interphase by type of over& positive dominance. F1 hybrids inherit the height of plants by types of positive dominance, intermediate inheritance and negative domination. The height of the attachment of the lower tier of the beans is largely determined by a combination of parent components. Thus, in the first generation in hybrid combinations there is the phenomenon of over dominance. Due to the yield and its components (seed yield, seed mass per plant, 1000 seeds, number of beans per plant, number of seeds per plant, number of seeds per seedpod) in all first generation hybrids heterosis is observed.

Growth, seed production, and dormancy of velvetleaf in response to shading were evaluated in the field. Velvetleaf plant height, leaf number, number of branches, and plant dry weight decreased linearly with increasing shade. No differences were observed for plant height, number of leaves, or branches/plant when plants were shaded 30% or not shaded throughout the growing season. However, the 76% shade treatment reduced velvetleaf height (1984 only), leaf number, stem branches, and plant dry weight. These reductions were greater in 1984 than 1985 except for plant dry weight that decreased by 88% each year. The number of capsules and the number of seeds/plant decreased linearly with increasing shade levels, while the seed weight increased with increasing shade level. Shading also decreased seed dormancy. These results demonstrate that shade suppresses velvetleaf growth and seed production, and shortens the dormancy of seeds that are produced by these plants.

Abstract A field experiment was carried out during spring season of 2016 and 2017 in the field of the Department of Field Crops - College of Agriculture - University of Anbar (Alternative Site – Abu Ghraib), to study the effect of concentration and Period of seed soaking with the Atonik growth regulator on the some quantitative traits of the mung bean (Al-Khadhrawi variety). Split plots arrangement according to randomized complete block design (RCBD) at three replications was used. The concentrations of soaking with Atonik (0, 2.5, 5- and 7.5-ml L-1) were the main plots, while the soaking period (0, 2, 4 and 6 hours) occupied the sub plots. The results showed that the seeds soaking with Atonik growth regulator at a 7.5 ml L-1 recorded the highest plant height (54.05 and 47.10 cm), number of pods (15.83 and 11.58 pods plant-1) and number of seeds (10.81 and 8.48 seeds pod-1) for both seasons respectively, and number of branches (14.33 branch plant-1) in the first season only. The soaking period for 6 hours was significantly superior and gave the highest plant height (54.23 and 46.59 cm), number of branches (14.00 and 12.80 plant branch- 1), number of pods (16.75 and 14.08 pod plant-1) and number of seeds (10.80 and 8.80 seed pod-1) for both seasons respectively. The interaction between concentrations of soaking at 7.5 ml L-1 and soaking period for 6 hours had highest values for more the studied traits and both seasons. We can bw conclude that the quantitative characteristics of the mung It can be improved by using seed soaking treatment before planting with Atonik growth regulator.

In the article, on the basis of regression analysis of the data, a forecast of the most important elements of the structure of productivity for the maximum specified yield of camelina sativa in the conditions of the Right-Bank Forest-Steppe of Ukraine in conditions of climate change is made. According to the assessment of the correlation relationships between the economically valuable breeding traits of camelina sativa, the studied indicators differ among themselves in terms of the level of interaction. The indicators of seed collection from one plant (r=0.98), the number of pods per plant (r=0.84) and plant safety (r=0.71) have a significant influence on the formation of productivity. The average correlation effect on productivity is the number of seeds per pod (r=0.44), the number of branches per plant (r=0.60), plant height (r=0.37) and the duration of the growing season (r=0.38). The mass of seeds per plant strongly depended on the number of pods per plant (r=0.85), but had an average positive correlation with the number of seeds per pod (r=0.48), the number of branches per plant (r=0.59), plant height (r=0.37), plant safety (r=0.62) and duration of the growing season (r=0.37). There is a weak negative relationship between the number of seeds in a pod and plant height (r=-0.29) and the duration of the growing season (r=-0.18), between the mass of a thousand seeds and the number of pods per plant (r=-0.08). Regression analysis of the entire array of experimental data made it possible to predict the value of the most important elements of the productivity structure for the maximum specified yield. For a maximum yield of 3.0–3.5 t/ha, the weight of seeds per plant should be 2.1–2.4 g, while the plant should form 13.4–15.9 branches, 159.5–182.1 pods and 16.8–19.5 seeds per pod. The mass of a thousand seeds should have 2.34–2.95 g, plant height 90.7–105.8 cm and plant safety at the level of 98.9 %, and the duration of the growing season should be in the range from 103 to 110 days.

In this paper, the results of the analysis of the variability of quantitative and qualitative decorative features of hybrid dahlia varieties (Dahlia x cultorum Thorsr. et Reis) used in landscaping of the Moscow region are considered. The following varieties are used in the work: Vesioly rebjata mix, Monarch mix, Butterfly Mix, Rumba white, Unwins Bedding Mix, Collarette Dandy Mix. To assess the variability, quantitative characteristics were selected: plant height, leaf size (length, width) and petiole, inflorescence diameter, tongue flower size, abundance of flowering (number of inflorescences per plant), duration of flowering; and qualitative: bush shape, compactness, type, color, glossiness, basket type, basket position relative to leaves, position, color of tongue flowers. The variability of quantitative features was assessed by calculating the coefficients of variation, the variability of qualitative features - by establishing the modalities and frequencies of occurrence. It was found that the studied varieties are the most variable in terms of plant height and the number of inflorescences on the plant, the most stable in terms of inflorescence sizes.

The aim of the study was to improve the method of soybean collection material assessment with the purpose of choosing pairs for hybridization using cluster analysis, to cluster samples according to the duration of growing period, plant height, the height of lower pod attachment, stem thickness in the lower part, the number of branches and productive joints on a plant, the number of pods and seeds per plant, the number of seeds in a pod, seed weight per plant, yield (g/m2 ), and the resistance to lodging and bean cracking. Based on the conducted cluster analysis of one hundred and forty-five soybean collection samples concerning the determined signs, it has been established that the collection material was distributed within five clusters. Soybean genotypes have been singled out as carriers of a high level of quantitative characteristics, especially the signs of yield potential which can be used as a promising selection material. The samples having analogous set of signs in the cluster and reliable distinction from others have been united in a separate cluster. The samples of the first cluster in the collection are characterized by average and close to average values of all the studied characteristics. The samples of the second cluster are characterized by high values as to the number of branches and productive joints on a plant and also the number of beans per plant. The third cluster consisted of samples having high values of the number of seeds in a bean. However, as to other signs, the samples of this group have low values. The samples of the fourth cluster are later-maturing, than those in the first three groups. They are characterized by larger plant height and the height of lower bean attachment. The fifth sample cluster is distinguished by the longest growing period and high values of the majority of signs except the number of seeds in a bean and also resistance to lodging and bean splitting. The parent forms were in four clusters out of five ones. The cluster analysis helped to conduct the choosing of parent pairs for hybridization and creation of soybean new initial material. The advantage of cluster analysis consists in being able to identify collection samples in balance according to the complex of valuable economic characteristics, rather than single out genotypes according to separate quantitative signs.

The study of the effect of three well known mutagens, ethyl methane sulphonate (EMS), methyl methane sulphonate (MMS) and gamma rays (GR) on the yield contributing traits of the urdbean variety TPU-4 were carried out in the M3 generation. Effect of selected mutagenic treatments/doses of EMS (0.02, 0.03 and 0.04 M), MMS (0.0025, 0.05 and 0.01 M) and (GR) (30, 40 and 50 KR) on different yield contributing traits like plant height, plant spread, number of pods per plant, pod length, number of seeds per pod, seed yield per plant and 100 seed weight were analyzed in the M3 populations of the variety TPU-4. Seeds of M2 plants and control were harvested separately and sown to raise M3 population.. Genetic variabilty in the mutagen administered M3 progeny of the urdbean variety TPU-4 was analyzed by employing statistical methods. Data on mean values and shift in the mean of seven quantitative traits was evaluated on individual plant basis. The experimental findings revealed that concentrations / dose of the all these mutagens showed inhibitory effect on plant height, number of pods per plant, pod length and number of seeds per pod. Lower concentrations of mutagens exerted a promotory effect on plant spread, 100 seed weight and seed yield per plant while higher concentrations of these mutagens inhibited them to different extent.

In Ghana, sesame is cultivated in some districts of northern Ghana. Genotypes cultivated are land races that are low yielding leading to decline in production. There is the need for improvement of these land races to generate high yielding cultivars. Characterization of genetic diversity of the sesame land races will be of great value in assisting in parental lines selection for sesame breeding programmes in Ghana. Twenty-five sesame land races were collected from five districts in northern Ghana noted for sesame cultivation. Seeds collected were planted in three replicates in randomized complete block design and were evaluated for a number of morphological characters. Data collected were subjected to Principal Component Analysis (PCA) and a dendrogram showing similarity between the accessions were drawn. Data on number of capsules per plant, number of seeds per capsule, and plant height at flowering were subjected to analysis of variance using GenStat Discovery Edition 4. Molecular genetic diversity was assessed by using thirty eight SSR markers widely distributed across sesame genome to characterize the materials. Twenty-one out of the 38 primers were polymorphic. Cluster analyses using the Euclidean similarity test and a complete link clustering method were used to make a dendrogram out of the morphological data. Analysis of variance showed that capsule number was significantly different; a range of 54.9 and 146.7 was produced. The number of seeds per capsule varied significantly and the variation between highest and lowest accession in seed production was 33%. Plant height was also significantly different ranging from 60.6 to 94.1 cm. Using morphological traits the accessions clustered into two major groups and two minor groups and variation among accessions were 10-61%. On the other hand, SSR marker-based dendrogram revealed five major and two minor groups. It showed that variation among the accessions was low, 10-20%. Heterozygosity was 0.52, total alleles produced were 410, and average allele per locus was 19.52. Six accessions, C3, C4, S5, W1, W3, and W5 fell in five different clusters in the SSR dendrogram and in six clusters in the morphomolecular based dendrogram. These accessions were noted for high capsule number per plant and seeds number per capsule and are recommended for consideration as potential parental lines for breeding programme for high yield.
