Interspecific Hybrids of Potato: Determination of Glycoalkaloid Aglycones and Influence of Bacterial Infection

Glycoalkaloid Content and Starch Structure in Solanum Species and Interspecific Somatic Potato Hybrids

When genome sections of wild Solanum species are bred into the cultivated potato (S. tuberosum L.) to obtain improved potato cultivars, the new cultivars must be evaluated for their beneficial and undesirable traits. Glycoalkaloids present in Solanum species are known for their toxic as well as for beneficial effects on mammals. On the other hand, glycoalkaloids in potato leaves provide natural...

Glycoalkaloid content and chemical composition of potatoes improved with nonconventional breeding approaches.

This paper reports the results of chemical analyses performed on two distinct groups of new potato genotypes. The first group contained five clones transformed with the gene ech42 encoding for an endochitinase. The second included 21 interspecific hybrids between the cultivated potato Solanum tuberosum and the wild species S. commersonii, obtained either by somatic fusion or by sexual hybridiza...

Glycoalkaloids as biomarkers for recognition of cultivated, wild, and somatic hybrids of potato.

Cultivated and wild potato species synthesize a wide variety of steroidal glycoalkaloids (GAs). During breeding programs, species genomes are often put together through either sexual or somatic hybridization. Therefore, the determination of the GA composition of hybrids is very important in that it may affect either human consumption, or resistance to pathogen and pests. Here, we report the res...

Budding Compatibility of Almond and Plum on Some Wild Species and Interspecific Hybrids of Almond

استقرار و پرآوری در کشت درون شیشه‌ای دو پایه هیبرید آلو × زردآلو

 This study was carried out to evaluate factors affecting establishment and proliferation of two apricot × plum (Prunus armenica × Prunus domestica) interspecific hybrids HS405 and HS706. These hybrid rootstocks are resistant to diseases and pathogens and have been developed in East Azarbayjan Agricultural and Natural Resources Research Center, Tabriz, Iran. Propagation of these hybrids through...
