Maqolada G. herbaceum × G. mustelinum amfidiploidlarining ikkinchi avlodida (F₂C) xo‘jalik-qimmatli belgilari (tola uzunligi, mustahkamligi, vegetatsiya davri) irsiylanishi hamda SSR markerlar yordamida polimorfizm darajasi baholangan. Tadqiqotda F₂C avlodda tola uzunligi bo‘yicha transgressiv shakllar aniqlanib, 35.1–37.0 mm va 39.1–41.0 mm gacha bo‘lgan uzun tola ko‘rsatkichlariga ega o‘simliklar ajratib olindi. Jami 72 ta SSR marker yordamida o‘tkazilgan tahlillarda 57 ta marker polimorf deb topildi. Alloheksaploid duragaylarda ota-ona shakllariga xos ayrim allellarning yo‘qolishi (20-23 ta) va yangi nodir allellarning (7-8 ta) paydo bo‘lishi kabi genomik o‘zgarishlar tasdiqlandi. Filogenetik tahlillar sintez qilingan duragaylarning ona shakliga nisbatan ko‘proq G. mustelinum turiga yaqinligini ko‘rsatdi.
