Linkage of the Rf1 gene in the T cytoplasm of maize with genes of the 3rd chromosome

  • Jan Vožda
Article

Abstract

The paper presents results obtained from studying the linkages of the Rf1 gene causing the restoration of fertility of pollen in the T type of cytoplasmic sterility of maize with signal genes of the 3rd chromosome in the F2 and B1 hybrid generations. Crossing of the fertility-restorer lines obtained on the basis of T cytoplasm with signal lines carrying recessive genes of the 3rd linkage group was carried out during the coupling phase.

The data obtained on the linkage of genes indicates that the Rf1 gene is located at the proximal end of the long arm of the 3rd chromosome between loci d1 and ba1. The linear sequence of genes and the map of their distances were determined on the basis of experimental recombined values as follows: d1−26−Rf1−16(?)−ba1−42−sh2.

Vazby génu Rf1—obnovitele fertility v „T” cytoplazmě kukuřice s gény 3 chromozómu

Сцепление гена ⋔1-восстановителя фертильностп пылыцы в «T» цитоплазме кукурузы с генами 3 хромосомы

Abstract

V práci bylo provedeno testování vazeb Rf1. génu podmiňujícího obnovení fertility pylu v „T” typu cytoplazmatické pylové sterility kukuřice se signalizačními gény 3 chromozómu v F2 a B1 generacích kříženců. Křižení linií—obnovitelů fertility ziskaných na bázi „T” cytoplazmy se signalizačními liniemi, nesoucími recesivní gény 3 vazbové skupiny, bylo provedeno ve fázi coupling.

Získané vazbové údaje ukazují, že Rf1 je možno umístit na proximálním konci dlouhého ramene 3 chromozómu mezi lokusy d1 a ba1. Lineární pořadí génů a mapa jejich vzdáleností byla prokázána na základě zjištěných rekombinačních hodnot následovně: d1−26−Rf1−16(?)−ba1−42−sh2.

Abstract

В работе приводятся данные по изучению сцеплений гена Rf1, обуславливающего восстановление фертильности пыльцы в «T» типе цитоплазматической мужской стерильности кукурузы, с генами-сигнализаторами третьей хромосомы в F2 и B1 генерациях гибридов. Скрещивание ливий—восстановителей фертильностк, полученных на базе «T» цитоплазмы, с линиями—ситнализаторами, несущими рецессивные гены третьей группы сцеплеяия, проводилось в фазе coupling.

Полученные данные о спеплении генов показывают, что ген Rf1 раснолагается на проксимальном конце длинного плеча 3 хромосомы между локусами d1 и ba1. Линейное размещение генов и их расстояния друг от друга на карте 3 хромосомы были установлены на основании найденных рекомбинационных значений следующим образом: d1−26−Rf1−16(?)−ba1−42−sh2
