Assessment of genetic diversity for various traits would contribute in hybridization projects in order to recover aspired recombinants. Therefore, metroglyph analysis and ANOVA were conducted out to estimate genetic diversity among seven caraway genotypes. Field experiment was applied in winter season of 2011/2012 with three replicates. Consequently, data were recorded on plant height, branches no., umbels no. umbels diameter, no. of umbellets and plant yield. Results showed that allotting of index scores for each trait of seven caraway genotypes represented the worth of the genotype in respects to the trait which the performance of genotype is represented by total index score for all traits of that genotype. Thus, Bery and Mosul genotypes ascertained the highest index scores of 16, for each one. Moreover, Metroglyph scatter diagram revealed three groups of caraway genotypes. Therefore, it could be concluded that metroglyph technique simply classified genotypes to groups and had potentiality to interpret genotypes performance regarding the index scores. Thus, it could be recommended to apply crossing or hybridization between individuals from different groups alternatively to individuals from same group. Genotypes of Bery, Mosul, Sury and selectedF1 (Group2), and Balady (Group3) were distinct which possible to apply crossing between one of group2 individuals with another one of group3.

Field experiment was conducted out Al-Anbar in winter season of 2011/2012 to investigate decision making of selection to the genotypes of caraway Carum carvi L. thus, to introduce in consequent breeding program and test effectiveness of GT Biplot and two model of multi-trait selection, master and against checks jointly in GGE Biplot software for seven genotypes by six traits of caraway. Genotypes were randomly distributed underwith RCBD design with three replicates. Results revealed that these techniques were effective to derived information from data. Where, GT Biplot extracted 92.6% of total variation. Furthermore, it was indicated that was significant association between plant height and umbellets no. which those traits were the closest to yield. Also, branches no. significantly correlated with umbels no. the previous technique distributed the genotypes selectedF1 and Balady with yield per plant and proportionally with plant height and umbellets no., Mosul and Bery with branches and umbels no. multi-trait selection-master derived five genotypes from seven viz., Bery, Balady, Mosul, Sury and rather selectedF1. Where, Bery is selected depended on umbels diameter and umbels no., Mosul on branches no., Balady on yield per plant and umbellets no. and Sury on plant height. Whereas, second model-against checks is represented as a filter for these traits and complementary for first model-master which umbel diameter and umbel no. were passed for genotype Bery, plant height and umbellets in Balady and plant height in Mosul. Finally, it could be inferred from these three techniques that the best three genotypes were namely Bery, Balady and Mosul. Moreover, the second model was rather similar to GT Biplot. Generally, those techniques were effectively mining information from multi-traits. Therefore, it could be recommended to introduce these genotypes by multi-traits in different years by locations trials to obtain most precisely informative data in order to establish breeding program and improvement of caraway.

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.

ABSTRACT The knowledge about genetic diversity of jatropha crop is important for genetic conservation resources and breeding of this species. The aim of this study was to evaluate the genetic diversity and performance of jatropha clones through morphological characterization to selection of clonal varieties for biofuels production. The clones were obtained through shoot cuttings from previous selection in a population of half-sibs progenies. The morphoagronomic analyses of clones was carried out at 180 days after transplantation and were evaluated plant height, stem diameter, number of primary branches and number of secondary branches, number of bunches and number of fruits per plant. Evaluating clones performance, significant results were found for the number of secondary branches. About analysis of genetic diversity, the measures of dissimilarity genetic varied from 0.62 to 13.11, this way, the UFRBPR14 and UFRBPR15 clones were more divergent. The Tocher method was efficient to verify formation of four groups. The characteristics that most contributed to the divergence among clones were branches number, height and number of bunches, and, stem diameter had lower contribution. The jatropha clones differed only in the secondary branches number and multivariate analysis showed divergence among the jatropha clones with formation of four groups. Also, branches number, plant height and number of bunches were characteristic that contributed to genetic divergence.

In field experiments performed in two localities (Smolice, Wrocław) 18 xenic hybrids of winter rye, two testers and standard cultivar Dańkowskie Złote, were analysed. The objects of detailed evaluations were 11 traits. For six of them arithmetic means (x), standard deviations (S), coefficients of variation (cv), coefficients of genetic diversity (h<sup>2</sup>), correlation coefficients were calculated. Moreover, analyses of variance were carried out and the effects of general (GCA) and specific (SCA) combining ability were estimated. The existence of quantitative xenia in hybrids was confirmed. It was shown that xenic hybrids, in respect to most of the analysed traits, were insignificantly inferior to the testers and the standard cultivar. However, the decrease of plant height has shown to be significant and a tendency to higher yield was observed.

Genetic Dissimilarity

Jatropha curcas L. (Euphorbiaceae) is a species grown in tropicalcountries and used for biodiesel production. Morphophysiological traits were analyzed to assess the genetic diversity in nine genotypes of J. curcas under deficit water. Seeds of plants from different populations, collected in diferente brazilian regions, were grown under two water regimes (100% and 50% tank capacity). Multivariate analysis was used to characterize genetic diversity. The UPGMA dendrogram built from the genetic distance group indicated the segregation of genotypes into five groups for growth traits and six groups for physiological traits. Then, an principal components analysis was carried out, to evaluate the pattern of character variations and then segregate the characteristics that could distinguish parental genotypes for use in plant breeding. Results showed 65.50% and 56.02% for the two first principal components of growth and physiological traits, respectively. Total root area was the most determining trait for genetic dissimilarity (18.9%) and group formation, followed by plant height (17.9%) and number of leaves (17.6%). On the other hand, stomatal conductance (gs) (24.9%) and guaiacol peroxidase (GPX) (20.9%) were the most determining physiological traits. The analysis of morphophysiological traits indicated CNPAE-298 and 299 as the most distant genotypes among the plant groups. Under water-limited conditions, total root area, plant height, gs and GPX were the most efficient traits to explain genetic dissimilarity among the genotypes, and for this reason they should be referred as a priority for further studies on genotypes selection in this species.

A 3-yr field experiment was conducted at the Scott Experimental Farm to determine the effect of the growth regulator, triapenthenol, on the growth and development of Argentine canola (Brassica napus L.). Triapenthenol reduced plant height 25–45 cm under optimal growing conditions. Increases in yield, branches and total pods were observed. Application at the bud stage was more effective than earlier treatment in the rosette. It was concluded that triapenthenol application to canola could be a useful management tool, particularly under optimal growing conditions.Key words: Canola, growth regulator, RSW-0411, lodging
