Abstract

Goal. Study of recombinant lines sweetcorn created and involved in the crossing of differentsubspecies, the allocation of these new sources of breeding and commercial signs.Results and discussion. Brought the results of the study in contrasting condition growing 53 linesof the sweet maize, received on program recombinogenesis of different subspecies of maize withuse monogenic endosperm mutation: su1, su2, wx, sh2. Significant polymorphism signmorрhostructure recombine line provides high genotypic different quality new source material.The Majority sign new lines characterize high absolute importance and exceed the factors of thematernal forms and standard. High heterogeneity for morphological sign - V=21,2- 49,4%provides their significant divergence from usual that is conditioned by germplasm distance ofparental component of the crossing.Conclusions. The Chosen sample-sources individual and complex sign. They are recommended asstandard when shaping sing collection and for making new able to meet competition hybrid sugarcorn. The Results of the estimation recombine line increase and enrich information an singdatabase to collections of the sugar corn.
