Horseradish cultivars are highly heterozygous clones and maintained through asexual propagation, using root cuttings. For many years, horseradish was believed to be sterile therefore impossible improve by traditional sexual crosses. Prior the 20th century, only way select plant cuttings from most desirable plants. Moreover, development of new improved has also been somewhat limited lack viable ...

Self-incompatibility in almond and Prunus species is an important trait that prevents self-fertilization. Selfincompatibility in almond is controlled gametophytically by the multiallelic S-locus. Present study was done in order to identification and preliminary selection of self compatible progenies resulted from controlled crosses in almond using specific primer SfF/SfR. Some important morphol...

Methods for phenotyping cowpeas for adaptation to drought are reviewed. Key factors involve achieving optimal time of flowering and cycle length, and appropriate morphology for different types of cultivars as they relate to their utilization for dry grain, hay, and fresh pea production. Strong resistance to vegetative-stage drought is available and should be incorporated. The extreme ability of...

Self-incompatibility is one of the most important difficulties in almond production which reduce fruit set dramatically and makes orchard management difficult. Therefore, breeding almond to produce self-compatible genotypes is very important. In this research identification and screening of 86 almond progenies obtained from selfing Touno after the self-pollination by PCR reaction with specific ...

BACKGROUND AND AIMS Although the apical development of wheat has been widely described, studies analysing how genetic breeding over the 20th century influenced the developmental phases and its consequences on yield generation are lacking, especially for durum wheat under field conditions in Mediterranean environments. The aims of this study were to analyse the effects of breeding in Spain and I...

Genetic diversity among sugarcane hybrids (Saccharum spp) is pre-requisite for sugarcane improvement through breeding. Twelve decamer oligonucleotide random-amplified polymorphic DNA (RAPD) markers were utilized to investigate the genetic potential among 24 sugarcane cultivars. A total of 120 fragments were originated by 12 RAPD primers. An average number of fragments were obtained as 11.42 fra...

Most Japanese plum-type cultivars are self-incompatible and therefore cross pollination is necessary to ensure fruit set. Moreover, pollen can directly affect fruit development process and quality.  This study was carried out to investigate the effect of 6 pollen sources (‘Goje Sabz’, ‘Simka’, ‘Shablon’, ‘Methley’, ‘Myrobalan’ and ‘Black Star’) on  fruit quantitative and qualitative characteris...

Genetic characterization, diversity analysis and estimate of the genetic relationship among varieties using functional and random DNA markers linked to agronomic traits can provide relevant guidelines in selecting parents and designing new breeding strategies for marker-assisted wheat cultivar improvement. Here, we characterize 20 Moroccan and 19 exotic bread wheat (Triticum aestivum L.) cultiv...

Characteristics and inheritance of rhizome coloration in the red lotus (Nelumbo nucifera) ‘Tomohiro’ were investigated to achieve stable production breeding cultivars. Rhizome proceeded from basal internodes distal ones during growing stage, enlarged rhizomes was completed October. No individuals with both white one plant found, there no a mottled pattern or an intermediate color between white....
