B.V.SUBSP. VULGARIS XB. V. SUBSP. MARTIMA در تلاقي RAPD مطالعه انحراف تفرق ژن هاي كنترل شده رنگ محور زيرلپه ، رنگ ساقه گل دهنده مقاومت به ريزومانيا و نشانگرهاي

Study of segregation distortion in the genes controlling hypocotyl and flowering stem pigmentation, resistance to rhizomania and RAPD markers in B.v. subsp. vulgaris * B.v. snbsp. maritima crosses Beta vulgaris subsp. vudgaris * Beta vulgaris subsp. marit

In this study, a rhizomania resistant wild beet accession. Beta. vulgaris subsp. maritime, WB42 was crossed in pairs with susceptible male-strile lines. Beta. vulgaris subsp. vulgaris and F1, F2 and BC1 populations were obtained. Hypocotyls and flowering stem pigmentation of WB42 were red and those of the susceptible lines were green. Segregation ratio of hypocotyls and flowering stem pigmentation and resistance to rhizomania genes as well as RAPD markers were assessed in segregating populations. No segregation distortion were observed for the genes controlling hypocotyl and flowering stem pigmentation and resistance to rhizomania, in segregating populations. The segregation distortion for RAPD markers in this crosses were lower than the B. vulgaris * B. vulgaris cross. It is concluded that the genetic background of B. v. subsp. maritime doesnʹt influence the amount of the segregation distortion in B. v. subsp vulgaris x B. v. subsp. maritima crosses.
