Three Japanese quail lines A-C were examined genetically using 13 micro-satellite markers to detect genetic diversity. The studied loci on average produced 5 alleles locus1 (range: 2-8). The mean observed Heterozygosity (Ho) was 0.609 and ranged across loci from 0.00-0.967 whereas the mean expected Heterozygosity (He) was 0.636 and ranged between 0.139 and 0.802. The Polymorphic Information Content (PIC) v alues varied among loci and ranged between 0.346 for locus GUJ0010 and 0.814 for locus GUJ0087 with overall mean 0.644. Differentiation among populations was moderate but highly significant (FST = 0.10, RST = 0.17; p<0.0001) however, within populations differentiation accounted for 3.61 and -0.73% of the total nuclear microsatellite variation under Infinite Allele Model (IAM) and Stepwise Mutation model (SSM), respectively. Cluster analysis based on Nei's genetic distance indicated that the studied populations formed two main groups. The 1st group included line A and the 2nd group harboured lines B and C. These results reflect that the set of studied markers can be used effectively to capture the magnitude of genetic variability in different Japanese quail populations. © Medwell Journals, 2011.

Types of wheat rust are among the most harmful diseases, which leads to a significant loss of yields. Under favorable conditions, the development of the disease can reduce the yield to 45% or more. During epiphytotic development, it covers an area of up to 1.5-2.0 mln ha and reduces the yields to 20-70%. Pathogens types of rust fungus diseases adapted to different climatic conditions, resulting in leaf rust meet annually and in all regions of wheat cultivation. Farms generally accepted crop protection from the disease by chemical means. However, the use of fungicides - is not only very costly, it is also environmentally safe, both for the near biological objects, and consumers received products. The most efficient and environmentally acceptable way to protect against the disease - a genetic. However, the gene pool of wheat resistance genes to rusts (P.recondita f. Sp. Tritici Rob. Ex Desm., P.graminis, P.striiformis) greatly exhausted, and every year there are new pathotypes of the pathogen able to overcome previous effective resistance genes (Lr, Sr, Yr-genes). Therefore, the stability test of wheat varieties and breeding for resistance is conducted in a continuous loop. The extension of genetic diversity of spring bread wheat varieties is possible by the involvement in hybridization of the new sources of valuable biological and economical features from the world's gene pool. The article on artificial infectious background investigation conducted spring wheat varieties for resistance to rusts and selected for the selection of resistant forms of immunity. The research revealed the forms resistant to leaf and stem rust and featuring high yielding potential.

In Kazakhstan, over the past decade, farmers’ attention has been directed towards the breeding of ostriches. Just a couple of farms used to breed emus, though mostly for tourist attraction, until few years ago when a research began by Kazakh National Agricultural University in order to assist Governmental program for developing agricultural industry. Today emu farming is still a new and developing part of poultry farming in Kazakhstan. By 2012, emu population in Kazakhstan was about 250 birds, out of which 200 were bred at farms in suburbs of Almaty city. Most of their owners still think of them mainly as pets or tourist attraction and do not pay a special care for their breeding and raising techniques. Most of these emu stocks have inadequate, proportion of males and females. Therefore, an attempt was made to study the effect of different male-female proportions of emu packs during breeding season. © Asian Network for Scientific Information, 2015.

This paper presents the results of studying the effect of planting density of a promising variety Yagodnyi 19 and the standard variety Nevsky on the yield and quality parameters of potato in the conditions of west Kazakhstan. Experimental factors included potato varieties (Nevsky and Yagodnyi 19) and different density planting (40,8, 47.6, 57.1 and 71.4 thou. pcs / ha). Studies showed that the optimum planting density is 57.1 thou. pcs / ha, at which the variety Nevsky formed a yield of - 25.43 thou / ha, Yagodnyi 19- 27.88 thou / ha. When the density was 57.1 thou pcs / ha, compared with the density 71.4 thou. pcs / ha seeds costs decrease by 25%. The average tuber weight decreases with the thickening of planting. With the increase of the planting norm, we can notice some decline in the marketability and an increase in the yield of seed tubers. Thus, there is a tendency of increasing starch and vitamin C content, and reducing the amount of nitrates in the tubers of the examined varieties.

Wheat leaf rust is an important disease of wheat, which causes economic damage to the country. Epiphytotic diseases of wheat rust cover the entire continents leading to catastrophic crop failures. In order to control the stability, it is very important to have available molecular genetic markers linked to these symptoms. As a result of the phytopathological evaluation of susceptibility to rust on the background of infectious diseases, we selected a number of samples resistant to Puccinia recondite f. sp. Tritici using the following molecular markers: F1.2245/Lr10-6/r2, csLV34, LN2/Ventriup and csGS-F/R. We identified 20 samples resistant to wheat stem rust. From the studied wheat material we identified nine samples with Lr10 gene, one with Lr34/Yr18 genes, 2 with complex genes Lr37/Sr38/Yr17 and 10 samples with Lr68 genes. The most valuable donor of sustainability is a promising line Almaly/Obriy, where 3 resistance genes Lr34/Yr18, Lr37/Sr38/Yr17, Lr68 and Yr2 were identified as well as Oktyabrina line with 2 resistance genes-Lr10 and Lr68. Our results provide an opportunity to move the selection process in Kazakhstan to a new scientific level by using molecular genetic techniques and technologies of MAS-breeding.
