- "Victoria" - yog lub caij nyoog ntxov thiab zoo tshaj plaws. Qhov ntev ntawm lub petioles yog me ntsis ntau tshaj li 60 cm Cov disadvantage ntawm no ntau yam yog tshaj flowering. Qhov zoo dua yog zoo heev saj zoo ntawm no rhubarb ntau yam, uas ua rau nws siv universal.
- "Zaryanka" - thaum ntxov-ripening ntau yam (thawj zaug sau nyob rau hauv 30 hnub los ntawm caij nplooj ntoos hlav regrowth). Qhov ntev ntawm lub petioles yog los ntawm 30 mus rau 44 cm. Qhov ntau yam ntawm rhubarb muaj peev xwm nruab nrab qhov nruab nrab.
- "Obskaya" - ntau medium-thaum ntxov (harvesting nyob rau hauv 60-69 hnub tom qab germination). Qhov ntev ntawm lub petioles yog 22-23 cm Qhov no ntau yam yog txias-resistant, tab sis tsis zam drought.
- "Quab yuam" - thaum ntxov ntau yam kabmob (ntxawm hauv 41-44 hnub txij thaum lub caij nplooj ntoo hlav). Petiole ntev 49-55 cm. Qhov no ntau yam tsis yog nws mus rau ntau flowering.

Loj hlob ntawm noob
Muaj ntau cov neeg novice agronomists yog xav, "Yuav ua li cas cog qoob loo ntawm cov noob?". Ua ntej koj yuav tsum soak lub noob nyob rau hauv dej ua ntej o, ces germinate lawv nyob rau hauv ntub gauze los yog burlap.
