HAPLOINDUCTORS ISOLATION IN MAIZE: THREE CYCLES OF SELECTION ON HIGH FREQUENCY OF INDUCTION OF MATROCLINAL HAPLOIDS
O.A. Shatskaya
With a using of hybridization of initial markers, revelation of individual plants with high frequency of induction and three cycles of selection during 14 generation of hybrid sample (РЕМ 48II x ЗМ 97)F1 the authors isolated maize haploinductors of ЗМК 1, ЗМК 1У and ЗМК 3 with high frequency of haploid induction — 5-7, 8-15 and 10-14 %, respectively. High effective haploinductors of ЗМК give an extended facility for using of haploidization method in breeding programs on isolation of maize homozygous lines.
Key words: Zea mays L., embryo marker, maternal haploids, haploid induction rate, inducers, selection.
