    Identification of interspecific barriers in the genus Lotus.

  • Original language description

    The genus Lotus is a large group comprising approximately 200 species. Lotus corniculatus is a dehiscent species with an indeterminated growth habit. It is a valuable forage species exhibiting several advantageous characteristics, such as high nutritivevalue, wide adaptation to soil, pH, and moisture, and low bloat hazard. However, its use has been somewhat restricted because of high seed costs. Pod shattering has been a major problem as seed loss is high due to the continuous flowering and time of podmaturity. Shattering resistance is a character of high heritability and in Lotus is considered to be controlled by more than one gene. Classical breeding approaches to reduce shattering through recurrent selection were unsuccessful (Grant 1996). Some species of Lotus reported to be indehiscent, L. conimbricensis, L. uliginosus and L. ornithopodioides, could be potential sources of genes conferred pod indehiscence. Natural interspecific hybridization does not appear in the genus Lotus. T

    Identifikace mezidruhových bariér křižitelnosti u rodu Lotus.

  • Czech description

    Rod Lotus obsahuje přibližně 200 druhů. L. corniculatus, hodnotná pícnina, se vyznačuje pukavými lusky, což je problematické z hlediska semenářství. Klasické metody odstraranění tohoto nedostatku jsou neúspěšné; určité možnosti nabízí mezidruhová hybridizace. Některé druhy v rámci rodu jsou nepukavé, L. conimbricensis, L. uliginosus a L. ornithopodioides, a jsou tedy vhodnými zdroji genů determinujících tento znak. Znak je determinován pravděpodobně více než jedním genem o vysoké heritabilitě. Cílem této práce bylo studium postzygotických bariér křižitelnosti a životaschopnost embryí prostřednictvím projasňování chloralhydrátem.
