In this study which was carried out during the 2015 summer season in Eskişehir, the flower, pod and seed characters attributed to yield components were investigated in 12 forage pea genotypes. They showed significant differences in terms of agronomic and morphological (flower, pod, and seed) traits. The highest fresh hay yield with 2171 kg/da and plant height with 106.6 cm were obtained from Populasyon-1. Crackerjack had lower values in some flower traits such as, whereas the higher values of pod and seed traits were obtained from cv. Rose. In addition, Population-1 included in the higher value group for standard petal width, keel petal length, calyx tube and teeth lengths, and flower length. Although cluster analysis did not reflect agronomic traits, the clustering resulted in four groups. The first group consisted of Özkaynak 1, 2, and 3 and Taşkent, Töre, and Population-2, which were the standard petal colour violet, light, and dark violet. Population-1 had both violet and white standard petal; however, it was included in the second group together with white-flowered Ulubatlı and Ürünlü according to cluster analysis. While Rose and Gölyazı were in the third group, Crackerjack was in the fourth group alone. There was a highly significant positive correlation between fresh hay yield and both standard petal width and length and flower length. Consequently, a hopeful result for summer growing in Eskişehir condition was obtained from Population-1. It was suggested that some flower characters can be used for pre-selection of yield-related traits in the evaluation of genetic diversity of pea germplasm through morphological trait.

Diallel crosses provide estimates of useful parameters in the selection of parents for hybridization. They also help in understanding the gene action behind the determination of characters of interest. The objective of this study was to determine the genetic control of flower traits in ornamental pepper based on a complete diallel with parents F1’s and reciprocal crosses. The experiment was conducted in a greenhouse at Laboratório de Biotecnologia Vegetal, Centro de Ciências Agrárias, Universidade Federal da Paraíba (CCA-UFPB). Seven accessions of ornamental pepper belonging to the CCA-UFPB Germplasm Bank UFPB001, UFPB004, UFPB77.3, UFPB099, UFPB134, UFPB137 and UFPB390 were used. The morphological analysis was performed on following quantitative Capsicum descriptors: days for flowering (DFL), flower diameter (FD), petal length (PL), number of petals (NP), number of stamens (NS), anther length (AL) and fillet length (FL). The data were previously submitted to analysis of variance and then to diallel analysis. All evaluated traits were adequate to the additive-dominant model. There are possibilities of genetic gains in breeding programs, for the NP, NS, AL and FL in ornamental peppers.

There are several factors that cause the production of flower cabbage fluctuate, including the cultivation system, the selection of varieties, as well as the determination of lip age. This study aims to obtain a combination of the age of seedlings and several varieties of flower cabbage (Brassica oleraceae L.). This research was conducted in the experimental land of the Faculty of Agriculture, Singaperbangsa Karawang University located in Pasirjengkol Village, Majalaya District, Karawang Regency, West Java Province. The research site was located at an elevation of 40 meters above sea level, in July – October 2020. The research method used is the experimental method and the experimental design used is a single-factor RandomIzed Design (RAK) with 8 combinations of treatments and repeated 4 times, so that there are 32 plots of experiments. The data were analyzed using variety analysis and advanced tests with multiple distance DMRT tests at a rate of 5%. The results of the study of a combination of the life of seedlings and some varieties of flower cabbage exerted a noticeable influence on the growth components (height of the plant and the number of leaves), as well as the yield components (the weight of flowers per plant, the wet weight of the header and the wet weight of the roots of the plant). In combination with the age of seedlings 21 days after seedlings (HSS) with varieties of flower cabbage PM 126 F1 gives the highest yield on crop weight of 22.46 grams / plant.

The objectives of the present study were to evaluate heterosis for grain yield and yield components in durum wheat, and to assess the prediction potential of amplified fragment length polymorphism (AFLP) based and agronomic trait based genetic distances (GD and MD, respectively) to F1 performance, mid parent heterosis (MPH), and specific combining ability effects (SCA) under well-watered and moisture stress conditions. Six parental genotypes with different responses to moisture stress and their 15 F1 crosses were evaluated for their responses to moisture stress conditions in a glasshouse. Some cross combinations showed significant MPH for grain yield and yield components. The expression of heterosis for grain yield was greater under moisture stress conditions than under well-watered conditions. Cluster analysis of the parental lines based on agronomic performance under stress conditions was similar to cluster analysis result based on AFLP marker profiles. F1 performance was strongly correlated to both SCA effects and MPH under both stress and well water conditions. The correlation between SCA and MPH was very high under both treatment conditions for all traits. Correlation between GD and MD was significant only under stress conditions. Positive correlation was found only for the association between GD v. F1 performance and GD v. SCA effects for harvest index (HI) under well-watered conditions. None of the correlations between MD and SCA effects were significant. The absence of association between GD and heterosis for yield and most agronomic traits implied that heterozygosity per se diversity is not a good predictor of heterosis or F1 performance under both well-watered and stressed conditions.

Breeding Material

Different genetic markers are used for estimation of breeding material, its characteristics and potential for ultimate aim - heterosis of hybrids. They also point out to the qualitative seed traits at the level of linkage with genes responsible for desirable agronomic traits. This program encompasses testing methodologies for the new seed technology. Genetic analysis of breeding material during certain phases is comprised of isozymic gene expression and degrees of their variability, but it is continued (in order to be evaluated) until determination of presence or absence of some genes existing or introduced for certain traits. Using combination of different molecular methods such as PCR, RAPD and AFLP based on polymorphism of DNA fragments, the definite aim - identification of newly created products of improvement is achieved. Testing of traits of breeding material, its genetic variability and diversity is the first stage in analysis of the maize genome. It is also the condition for determination of presence of certain genes, used for obtaining the ultimate aim - attest of identity of the genotype.

AbstractA basic problem of cluster analysis is the determination or selection of the number of clusters evinced in any set of data. We address this issue with multinomial data using Akaike’s information criterion and demonstrate its utility in identifying an appropriate number of clusters of tumor types with similar profiles of cell surface antigens.

Selection of the appropriate composition desalination units can be done with a variety of method approaches, one of the method is the Analytic Hierarchy Process. In determining the desalination unit with AHP method to consider is setting a goal, an alternative criteria and pairwise comparison. Research for the determination of the exact composition of the desalination unit in order to achieve sustainable drinking water suppy in coastal areas and small islands has been conducted. The results of the study are as follows, the energy demand of 50.83%, operator costs of 26.64%, maintenance costs of 14.13% and chemical requirement 8.4%. For an alternative composition desalination unit of RO 10 m3 / day is the best alternative composition with value of 59.61%, the composition of the next alternative is RO 20 m3/ day of 30.40% and the last alternative of the desalination unit composition is RO 120 m3/ day of 09.99%.Key words : Desalination, Mukti Stage Flash Composition, AHP
