Abstract Barley (Hordeum vulgare L.) is an important economic crop for food, feed and industrial raw materials. In the present research, 112 barley landraces from the Shanghai region were genotyped using genotyping-by-sequencing (GBS), and the genetic diversity and population structure were analyzed. The results showed that 210,268 Single Nucleotide Polymorphisms (SNPs) were present in total, and the average poly-morphism information content (PIC) was 0.1642. Genetic diversity and population structure analyses suggested that these barley landraces were differentiated and could be divided into three sub-groups, with morphological traits of row-type and adherence of the hulls the main distinguishing More >

Abstract Forty-four V. dahliae isolates were collected from symptomatic vascular tissues of okra plants each from a different field in eight provinces located in the eastern Mediterranean and western Anatolia regions of Turkey during 2006- 2009. Nitrate-nonutilizing (nit) mutants of V. dahliae from okra were used to determine heterokaryosis and genetic relatedness among isolates. All isolates from okra plants were grouped into two vegetative compatibility groups (VCGs) (1 and 2) and three subgroups as 1A (13.6%, 6/44), 2A (20.5%, 9/44) and 2B (65.9%, 29/44) according to international criteria. Pathogenicity tests were performed on a susceptible local okra (A. esculentus) landrace… More >

Abstract Knowledge of the genetic components of agronomic traits is an important factor to characterize landraces of maize to make them useful in plant breeding programs. The objective of this work was to know the genetic action and combining ability of several agronomic traits of five maize races and their crosses. Maize landraces analyzed were Jala, Tuxpeño, Celaya, Pepitilla and Dulce. Plant height, days to male and female flowering date after planting, and dry matter and grain yields were recorded. Those variables showed highly significant differences among genotypes. With the exception of dry matter yield, the More >

Abstract The objective of this study were to estimate selection, simultaneous selection of independent characters, and genetics gain, in a recurrent selection program of full-sib families in two corn populations. We evaluated 81 families under irrigation of two native populations of Pinto Amarillo of maize numbers "15" and "45" at the experimental field of the Faculty of Agronomy of the UANL, México. The experimental design was a 9x9 alfa-lattice with three replications; the study variables included plant height, ear height, days to male and female flowering, grain yield, ear length, ear diameter and number of rows More >
