چکیده

Purpose. Investigation of cytogenetic aspects embryological processes in the culture immature apomictic embryos, breeding genotypes sugar beet with cytoplasmic sterility for differentiation and selection by gametophyte reduced parthenogenesis.
 Methods. Cytological, biotechnological, fluorescent cytophotometry, field, laboratory.
 Results. The features genesis embryos cells induced vitro on 12th, 20th 22th days development have been investigated basis CMS apozygotic lines Beta vulgaris alloplasmic wild species maritime patula. Indicators efficiency haploid parthenogenesis significantly exceeded best technologies pollen-sterile from 3.79% to 6.25% had a value 62.2%, 24.8%, 16.7%, respectively. Stabilization genome ploidy diploid was carried out selected numbers without colchicine, based evaluation using software analyzer (AP) Partec.
 Conclusions. induction as affected genetic potential cytoplasm taking into account total percentage haploids (50 units; 100 units) myxoploids has investigated. Homozygous were created stabilizing myxoploid micro sprouts during III–IV passages use colchicine. Technologies rooting open ground process beets improved.

Post-meiotic apozygotic combinatory process in sugar beet (Beta vulgaris L.)

The effect of colchicine on phenotypic classes ratio of the enzyme locus controlling alcohol dehydrogenase (ADH1) in sugar beet agamospermous progenies was analysed. The obtained data are indicative of the thing that colchicine causes polytenization of homological chromosome regions carrying marker locus Adh1 alleles. Theoretical calculation of the formation of egg cells frequencies and those o...

Sugar beet (Beta vulgaris L.).

Creating transgenic plants is invaluable for the genetic analysis of sugar beet and will be increasingly important as sugar beet genomic technologies progress. A protocol for Agrobacterium-mediated transformation of sugar beet is described in this chapter. Our protocol is optimized for a sugar beet genotype that performs exceptionally well in tissue culture, including the steps of dedifferentia...

Effects ofpollinator line characteristics on quantity and quality of monogerm hybrid seed production in sugar beet (Beta vulgaris L.)

A two-year experiment was carried out to study the effects of pollinator line characteristicson the quantity and quality of monogerm hybrid seed production in sugar beet (Beta vulgaris L.)and select proper pollinator for five promising sugar beet cytoplasmic male sterile lines (CMSs)during 2012-2013 growing seasons. In this study, four diploid pollinator lines were crossed byfive CMSs of sugar ...

A morphogenetic crop model for sugar-beet (Beta vulgaris L.)

This paper is the instructions for the proceeding of the International Symposium on Crop. Sugar beet crop models have rarely taken into account the morphogenetic process generating plant architecture despite the fact that plant architectural plasticity plays a key role during growth, especially under stress conditions. The objective of this paper is to develop this approach by applying the Gree...

Utilization of Univariate Parametric and non-Parametric Methods in the Stability Analysis of Sugar Yield in Sugar Beet (Beta vulgaris L.) Hybrids

Extended Abstract Introduction and Objective: Sugar is a tonic that produces a large amount of energy in the diet of the world's population. The position of sugar beet in providing part of the sugar required by human society is not hidden from anyone. Given the needs of society, breeding sugar beet hybrids that is high in quantity and quality is inevitable. In addition to plant genetics and ...
