The results of morphological and AFLP variability of 120 plants of carob tree (Ceratonia siliqua L.), collected from 12 different locations (10 biological replicates for each location) on the coast and islands of the southern Croatian Adriatic, indicate high molecular and morphological variability among these carob populations. Analysis of molecular variance revealed significant differences among populations (26.07%; p < 0.001; a = 0.05). Out of the total variability, 22.49% refers to the variability among, and 77.51% within populations. UPGMA and STRUCTURE analysis based on AFLP genetic data clustered carob populations into three main groups representing three real genetic populations. UPGMA analysis based on morphological traits of leaves, pods, and seeds clustered carob populations into five groups. Mantel test showed significant correlation between morphological and genetic data (r = 0.58, p < 0.001; a = 0.05). According to the high genetic and morphological variability, the germplasm collection in the analysis could represent an important genetic pool for future breeding programmes. The goal of future research should be the conservation of C. siliqua in its natural habitats, and the establishment of gene banks of genetic resources with the purpose of creating new carob cultivars in breeding programmes.

It is due to the lack of renewable fiber sources for industrial purposes that the need for finding available and alternative material has become imperative. Kenaf (Hibiscus cannabinus L.), a fast-growing industrial crop, would be a potential solution for valorizing salinized lands and/or soils irrigated with saline water. With the aim of selecting and valorizing salt-tolerant species with high fiber yields and industrial values, we launched the assessment of the performance of kenaf culture (var. Guangdong 743-2) under salinity constraints. Germination and vegetative stages were considered in the present study to better evaluate the whole life cycle of the species. …

Salt stress during germination degenerates crop establishment and declines yield in wheat (Triticum subsp.). Against salt (NaCl) stress, we investigated 12 bread (Triticum aestivum L.) and 10 einkorn wheat (T. monococcum subsp. monococcum) entries for germination rate, germinating power, coleoptile length, shoot length, root length, shoot/root length ratio, root fresh weight, root dry weight, and root fresh/dry weigh ratio. An effective blocking in variance analysis improved statistical significance and differentiation between germination stages and wheat entries. Salt total and salt ranking tolerance indices grouped the wheat entries into tolerant (Bayraktar 2000, Gerek 79, İkizce 96, Gün 91, Demir 2000, and …

Turkish Journal of Agriculture and Forestry
In order to determine the overall degree of polymorphism and detect similarities among genotypes, 19 almond [Prunus dulcis (Mill.) D.A.Webb] genotypes were studied. Variation in traits related to phenology, morphology, and fruit quality was observed, and the results indicated a high morphological diversity of almond genotypes. The majority of important correlations were determined among the traits representing nut size (nut width, nut length, nut thickness, and nut weight) and leaf size (leaf length, leaf width, and leaf area). The lack of correlation between kernel size and chemical compounds enables the creation of a new almond cultivar with large kernels and …
