Marker-Assisted Selection for Early Maturing E Loci in Soybean Yielded Prospective Breeding Lines for High Latitudes of Northern Kazakhstan

The photoperiodic sensitivity of soybean (Glycine max L.) is one the limiting factors affecting plant growth and yield. At higher latitudes, early flowering maturity with neutral reaction to photoperiods are required for adaptation plants long-day conditions. Currently, production distribution new varieties soybeans adapted widespread agricultural regions in northern Kazakhstan strong demand. Eleven hybrid populations were obtained from crosses between 17 parents four groups, MG 000, 00, 0, I. Marker-assisted selection (MAS) was assessed suitable SSR markers successfully applied genes E1, E3, E4, E7, targeting homozygous genotypes recessive alleles. identified selected propagated tested conditions 53° N latitude Kostanay region Kazakhstan. Finally, 20 maturing F4 breeding lines developed e1 e3 E4 e7, E3 e4 all completing their period within 92–102 days. These by MAS should provide very prospective superior through a strategy that may be helpful other countries high latitudes.
