Relevance. One of the main methods for solving the problem of providing the population of the Russian Federation with vegetable and melon products is the development of selection and seed production. The creation of new competitive varieties and hybrids will enable the vegetable industry to transfer to a qualitatively new level of development.Material and methods.The object of research is new varieties and hybrids of watermelon, melon and pumpkin, created at the Bykov experimental station in the rainfed conditions of the Volgograd TransVolga region. Methods of creation are intervarietal and interlinear hybridization. Results and conclusions.As a result of breeding work at the station, a number of varieties and heterosis hybrids of melons and gourds were created, which significantly expanded the assortment of the melon breeding industry. Over the past 5 years, 4 varieties of watermelon, 2 heterotic hybrids of watermelon, 3 varieties of melon and 1 grade of pumpkin have been included in the State Register of Breeding Achievements. The assortment of new varieties varies in terms of ripening, dry matter content, shape and color of the fruit background, as well as in color and pulp consistency. The length of the growing season of the created varieties and hybrids of watermelon ranges from 63 days in early ripening (Duet F1, Temp F1, Meteor) to 85 in the mid-ripening variety Malachite. The highest solids content of the new variety of watermelon Medunok is up to 14%. Among melon varieties, the shortest growing season is characterized by the Comet variety up to 70 days. All varieties have a high solids content of 14.0-19.0% and a thick flesh. Promising pumpkin varieties are distinguished by a bright coloration of the pulp, a high carotene content and a long storage period. Thus, the introduction of new varieties of gourds in commodity and home garden melon farming will allow the conveyor growing of products, increase the product mix and the period of consumption of fresh produce.

Relevance. The soil and climatic conditions of the Lower Trans-Volga region are considered favorable for melon growing and make it possible to obtain high-quality products. The purpose of the research was to create new competitive varieties and hybrids of melon and pumpkin.Materials and methods. The object of the research is new varieties of melon and butternut pumpkin created at the Bykovskaya melon breeding experimental station. Melon cultivar Osen and pumpkin cv. Zhemchuzhina were used as standards. The methods of creation are intervarietal hybridization, individual and mass selection. During the growing season, appropriate observations and counts were carried out.Results. As a result of many years of breeding work at the Bykovskaya cucurbits selection experimental station, a melon cultivar 251 and a pumpkin cultivar 509 have been created. both producers and consumers. Therefore, the obtained varieties were evaluated for taste, yield, resistance to biological and abiofactors of the environment, dry matter content, fruit size, fruit and pulp color. During the comparative assessment of the accessions, it was determined that the new varieties of melon and pumpkin exceed the standards in terms of the main economically valuable traits. The average yield during the study, in the melon cultivar 251, exceeded the standard by 47.8%. In the pumpkin cultivar, the average yield for three years of research exceeded the standard by 69.6%. In terms of taste, the new melon variety was at the level of the standard, the cv. Osen. A variety of butternut pumpkin exceeded the standard in all quality indicators. The susceptibility to powdery mildew in the melon cultivar varied depending on the year of research. The melon sample showed resistance to anthracnose higher than the standard by 16.4 and 18.6%, over the years of study. In the pumpkin cultivar, resistance to powdery mildew and anthracnose was higher than the standard, on average by 34.9% to powdery mildew and by 28.6% to anthracnose. Thus, new varieties of melon and pumpkin meet the modern requirements of the industrial melon industry, are resistant to environmental stress factors, common diseases, and have economically valuable traits.

Diphasiastrum zeilleri (Rouy) Holub is a hybrid species, with the formula D. complanatum (L.) Holub × D. tristachyum (Pursh) Holub. A high variability of D. zeilleri is due to environmental conditions (light and shadow ecological forms) and probably to introgressive hybridization with the parental species. Intermediate forms between D. zeilleri, D. complanatum and D. tristachyum are quite rare, that allows to treat the three taxa as separate species. D. zeilleri is missing in subarctic regions of Europe and North America, and some degree of its resemblance with D. complanatum subsp. montellii Kukk. is convergent. Lycopodium complanatum f. polystachyum H. Lindb. is considered to belong to D. zeilleri, and an appropriate conbination is published, Diphasiastrum zeilleri var. polystachyum (H. Lindb.) Ivanenko. A new variety Diphasiastrum zeilleri (Rouy) Holub var. ramistachyum Ivanenko is described, differing by sessile strobili formed on the basal part of fertile branches during one growing season. The structure, the base of which is a fertile branch, and the upper part is strobilus (strobili), is proposed to term «strobilus branch». Besides D. zeilleri var. ramistachyum, the strobilus branches are produced by D. issleri (Rouy) Holub, D. oellgaardii Stoor, Boudrie, Jérôme, K. Horn et Bennert, and rarely by D. alpinum (L.) Holub and D. complanatum.

The experiment was conducted to examine the effect of freezing and defrosting methods on the quality of beef. Two types of beef samples named as fresh and cured beef samples were taken. Both types were divided into three sub divisions namely air, water and microwave oven. These samples were stored at -20°C temperature in the freezer for 90 days and analyzed on 10th, 45th and 90th day. The dry matter, crude protein, ether extract and ash percentages and standard plate count (SPC) were differed significantly (p<0.01) among the air, water and microwave defrosted samples. Up to 90th days of freezing at -200C dry matter content increased with the increase of storage time almost in all samples except microwave fresh samples. The protein content decreased with the increase of storage time from 10 to 45 days but increased from 45 to 90 days. The ash content decreased with the increase of storage time in case of fresh frozen samples but increased with the increase of storage time in case of cured frozen samples except microwave oven cured sample. Ether extract value gradually increased with the increasing of storage period in case of air fresh, water fresh, air cured and water cured frozen samples but decreased with the increasing of storage period in case of microwave oven fresh and microwave oven cured samples. The SPC value increased with the increase of storage time in case of all samples and differed significantly (p<0.01) among the parameters. The cured microwave defrosted beef was proved as the best technique of defrosting frozen beef.DOI: http://dx.doi.org/10.3329/bjas.v43i3.21649 Bang. J. Anim. Sci. 2014. 43 (3): 202-206

Samples of forages were collected throughout the growing season from two dehydrating plants at three different stages of processing: prior to drying, after drying and after pelleting. Samples were analyzed for dry matter, crude protein, fibre, nitrogen content of the acid detergent fibre and pepsin insoluble nitrogen. On the average the amount of heat damage present in the dehydrated samples was quite low (6.11 ADIN % N). There was significantly more heat damage in the samples from the Creston plant. The dry matter content of the material leaving the drier appears to be the main factor related to elevated heat damage.

Roots of orange fleshed sweet potato varieties currently available in Nigeria contain high quantities of β-carotene or pro-vitamin A but have high moisture content. These varieties have been found to be a cheap and important remedy for vitamin A deficiency. The cream or white fleshed varieties on the other hand, have sweet taste with high dry matter content, giving a dry texture, a quality trait preferred in Nigeria. The objectives of this study were to examine the quantitative inheritance of important traits in sweet potato by means of a diallel analysis with a view to estimating the GCA and SCA components of genetic variance, and to determine the associated type of gene action controlling β-carotene content and root dry mass. A diallel crosses experiment using six parental sweet potato genotypes crossed in all possible combinations were carried out. Resultant thirty progenies were evaluated for beta carotene (β-carotene) and dry matter content in Landmark University, Omu Aran, Kwara State, Nigeria during the cropping season of 2012 and 2013. The 30 F1 progenies along with their parental lines were planted in the same field trial. The trial was laid out in 6 x 6 triple lattice in two replications. Highly significant (P≤ 0.01) differences were observed among the genotypes for all the tested traits. The average β-carotene content for the progenies was 2.86 (mg/100 g f.w.) while the dry matter content was 31.89%. The cross combination 199024.2 x Excel recorded the highest beta carotene (14.37 mg/100 g f.w) and dry matter content (40.10%), this candidate is therefore suggested for further evaluation. Key words: Diallel analysis, Dry matter, Southern Guinea Savanna, Sweet potato, Vitamin A, β-carotene.
