Today climate change threatens to reduce crop yield and harming the food security. Local landraces have adaptation skills shifting climatic conditions. Using of this local source in plant breeding programs becoming an alternative strategy. In study, 97 were collected initiate bulb onion program eligible for current trends. Collected materials morphologically characterized using 21 descriptors, ...

Using SSR, a molecular marker, this study aimed to evaluate the genetic diversity and relationship among 55 herbaceous peony (Paeonia lactiflora Pall.) cultivars belonging Lactiflora, Hybrid Itoh Groups lay foundation for classification of cultivars, as well background analysis breeding new cultivars. Our results show that 86 alleles, 76 which were polymorphic, obtained by screening 13 pairs po...

Coffee plays an important role in the global economy, human health and society. It is one of major cash crops constituting backbone Nigerian economy before emergence re-emergence petroleum oil. Molecular markers are reliable valuable tool for analyzing polymorphism, screening selection desirable genotypes breeding programs. The study aimed at determining genetic diversity among coffee genotypes...

Current Pennisetum glaucum (L.) R. BR. cultivars in Namibia have overall poor performance posing a threat to the nation's food security because this crop is staple for over 70% of the Namibian population. The crop suffers from undesirable production traits such as susceptibility to diseases, low yield, and prolonged reproductive cycle. This study aimed to understand the genetic diversity of the...

Trichoderma species are commercially applied as biocontrol agents against numerous plant pathogenic fungi due to their production of antifungal metabolites, competition for nutrients and space, and mycoparasitism. However, currently the identification of Trichoderma species from throughout the world based on micro-morphological descriptions is tedious and prone to error. The correct identificat...

BACKGROUND To evaluate genetic variation, population structure, and the extent of linkage disequilibrium (LD), 134 switchgrass (Panicum virgatum L.) samples were analyzed with 51 markers, including 16 ISSRs, 20 SCoTs, and 15 EST-SSRs. RESULTS In this study, a high level of genetic variation was observed in the switchgrass samples and they had an average Nei's gene diversity index (H) of 0.311...

A phylogenetic tree is a visual diagram of the relationship between a set of biological species. The scientists usually use it to analyze many characteristics of the species. The distance-matrix methods, such as Unweighted Pair Group Method with Arithmetic Mean and Neighbor Joining, construct a phylogenetic tree by calculating pairwise genetic distances between taxa. These methods have the comp...

This study carried out for determination and discrimination of intraspecific diversity of Astragalus verus and Astragalus glaucops by Eco-phytosociological method from west of Iran. In this order, application of Endogenous milieu (special station) for data collecting and then their analyzing permit us only determine existence of inter and intraspecific diversity. Then for determinating kind and...

This study evaluated different strategies to select sugar cane families and obtain clones adapted to the conditions of the Brazilian savannah. Specifically, 7 experiments were conducted, with 10 full sib families, and 2 witnesses in common to all experiments, in each experiment. The plants were grown in random blocks, with witnesses in common (incomplete blocks), and 6 repetitions of each exper...

A biogeographical classification of reptiles in the Riff region (northern Morocco, Africa) was carried out to look for shared distribution patterns, here termed chorotypes. Baroni-Urbani & Buser’s similarity index was applied to the presence/absence data of reptiles in 10#10 km UTM (Universal Transverse Mercator) squares, and then UPGMA (Unweighted Pair-Group Method using arithmetic average) wa...
