Salivary gland chromosome map of Zaprionus inermis

Article Abstract:

A formal polytene chromosome map for Zaprionus inermis is presented. This species carries five rod-shaped and one dot chromosome similar to Drosophila. The chromosomes were found to be quite fragile and may be susceptible to ectopic pairing. Difficulty was encountered in the analysis due to tight coiling and twisting of the chromosomes. No strong homologies could be drawn between the Z. inermis chromosome map and those of Z. tuberculatus, Z. indianus and Drosophila, despite the sharing of morphologic features. This argues against the development of Zaprionus from D. migrans.

Introgression mapping of genes for winter hardiness and frost tolerance transferred from Festuca arundinacea into Lolium multiflorum

Article Abstract:

The first example of a backcross-breeding program aimed at the transfer of winter hardiness and frost tolerance genes from Festuca arundinacea into winter-sensitivity Lolium multiflorum were studied. It is found that an appropriate single Festuca introgression in an otherwise undisturbed Lolium genome could provide increased winter hardiness and frost tolerance without compromise to the good growth and vigor found in Lolium.
