genetic breeding; Repeatability; Saccharum spp

Sixty-eight sugarcane genotypes were evaluated to determine the number of harvests required to select new genotypes in the sugarcane belt in the state of Pernambuco, northeast Brazil. Using a random block design, the following parameters were evaluated: (i) polarizable sugars (POL) per hectare, in metric tons (TPH); (ii) culm productivity per hectare (TCH); (iii) ... more

Gene action; General and specific combining ability; genetic breeding; Phaseolus vulgaris

The search for genetic material of snap beans with desirable yield traits is of utmost importance for yield increase in Brazil. We evaluated 12 snap bean genotypes by diallel crosses that presented characteristics of interest, so as to select the best genitors to generate productive populations in the snap bean breeding program of the Universidade Estadual do Norte ... more

Capsicum spp; genetic breeding; Genetic diversity; RAPD

Pepper species exhibit broad genetic diversity, which enables their use in breeding programs. The objective of this study was to characterize the diversity between the parents of different species and their interspecific hybrids using morphological and molecular markers. The parents of Capsicum annuum (UFPB-01 and -137), C. baccatum (UFPB-72), and C. chinense ( ... more

Conservation; Genetic diversity; Simple sequence repeat; Wild soybean

Annual wild soybean (Glycine soja Sieb. et Zucc.), the ancestor of cultivated soybean (G. max), is believed to be a potential gene source for further improvement of soybean to cope with environmental stress. In this study, 10 simple sequence repeat (SSR) markers were used to evaluate the genetic diversity and population genetic structure in five wild soybean populations using ... more

Genetic diversity; Genic-SSRs; Nelumbo nucifera; Transcriptome

Nelumbo nucifera is an important economic vegetable and traditional medicine, but available genetic resources remain limited. Next generation sequencing has proven to be a rapid and effective means of identifying genic simple sequence repeat (genic-SSR) markers. This study developed genic-SSRs for N. nucifera using Illumina sequencing technology to assess diversity across ... more

Abelmoschus esculentus; Genetic diversity; Population structure; Retrotransposons; Turkish landraces

Lack of requisite genetic variation in Turkish okra has necessitated the use of different types of markers for estimating the genetic diversity and identifying the source of variation. Transposable elements, present abundantly in plant genomes, generate genomic diversity through their replication and are thus an excellent source of molecular markers. We hypothesized that inter-primer binding ... more

Disease resistance; Evolution; Expressed sequence tag-simple sequence repeat; Genetic diversity; Gossypium

Cotton (Gossypium spp) is one of the most economically important crops that provide the world’s most widely used natural fiber. Diseases such as Fusarium wilt and particularly Verticillium wilt seriously affect cotton production, and thus breeding for disease resistance is one of the most important goals of cotton breeding programs. Currently, potential exists to improve disease ... more

Curcuma wenyujin; Genetic diversity; Inter simple sequence repeat (ISSR); Phylogenetic analysis; Population; Random amplified polymorphic DNA (RAPD)

Curcuma wenyujin is an important multifunctional medicinal herb in China. Currently, populations of C. wenyujin are decreasing, and wild individuals have almost disappeared from their natural habitats. Moreover, little is known regarding the molecular characteristics of this plant. In this study, we investigated the genetic diversity and variation of five populations of ... more
