Kendine Fertil Ve Kendine Steril Monogerm Şeker Pancarı Populasyonları İçerisinden O-Tipi Bitki Seçimi

Abstract

This research was made in 1989-1991 in Tokat. The paire-maid was crossed with 293 pollinators which belong to 6 diploid genetic monogerm sugarbeet lines. One of the pollinators died, 45 of them were trotzer and 38 of them devemalizating. 3 male sterile plants of the paire-made died. 31 of them were trotzer, and 52 of them devemalizating. Totally, Fj seeds were harvested from 204 male-sterile parents, and inbred seeds were harvested 110 from pollinators of the paire-made. Amount of seeds of the male-sterile and male parents were low. Vigority of the inbred seed was founded low because of the inbred depression. Explant which belong to pollinators were surface sterilized. Then, the explants were planted on the basic MS medium with the 1 mg/1 BA, 5 mg/1 IBA, 20 g/1 sugar, 2 mg/1 cloramphenicol, 8 g/1 agar and adjusted pH= 5.8. Totally, 307 shoots were stimulated. 2041 Fi progenies belong to male sterile parents of the paire-maid were controlled for male sterility. Any male sterile parent was not founded that all of their progenies were male sterile.
