Cultivated asparagus (Asparagus officinalis L.) is an economically important plant worldwide. “Morado de Huetor” is a Spanish autochthonous landrace characterized by their longevity, organoleptic characteristics, differential biocompound content and high heterozygosity, resulting in heterogeneous plantations with limited productivity. Consequently, this(More)
Octoploid genotypes of Asparagus officinalis L. cv. ‘Morado de Huetor’, a tetraploid Spanish landrace, were successfully induced by treating in vitro rhizome buds explants with colchicine. Pulses during 24 h with different concentrations of colchicine are able to induce polyploid plants, colchicine applied at 0.1 % induce a 7 % of octoploid genotypes with a(More)
An efficient micropropagation method for asparagus species was developed in this study. The method allows the fast cloning of the elite genotypes from different asparagus species and the interspecific hybrids obtained from these species. Rhizome bud explants were disinfected using 3 g l−1 of benomyl and 20 g l−1 of sodium hypochlorite. Then, they were(More)
Asparagus maritimus is a species distributed in sandy soils along the Mediterranean coast. It has been reported as salt tolerant and resistant to rust. The wild asparagus species are a very important genetic resources for asparagus breeding because the current commercial cultivars have a narrow genetic base. Until recently, the only population of A.(More)
Anther culture is used to develop asparagus “super-male” (di-haploids) in asparagus, which can be used to develop “all-male” varieties, by crossing them with suitable females; their progenies will be formed only by males which is advantageous for producers. This report describe a new anther culture protocol adapted to “Morado de Huétor”, a Spanish(More)
Polyploid plants have been induced in different Asparagus officinalis L. breeding programs in order to obtain plants with improved agronomical traits, such as large spear diameter or segregation ratios with a higher number of males. The polyploidization methods can produce somaclonal variation in the polyploid plants obtained and, therefore, unwanted(More)

The Philippines is considered to be one of the world's most disaster prone countries. Since the use of mobile devices continues to grow, many generated applications for mobile devices that will aid during disaster. While most of the people residing in the urban areas are mostly smartphone users, people who are living in the rural areas are still using(More)
Sagittal rotational malunion after distal radius fractures was identified in eight patients by the presence of a "hinge" point on the volar cortex on the lateral radiograph, and the ulnar head being shorter than the anterior lip of the radius on the posterior-anterior radiograph. The surgical correction consisted of preplating the distal fragment with a(More)
