CHARACTERISTICS OF SUITABILITY FOR MACHINE MILKING OF SIMMENTAL COWS AND ITS CROSS-BREED WITH RED-AND-WHITE HOLSTEINS

Для характеристики пригодности к машинному доению коров разной степени кровности по симментальской породе в условиях Поволжья были оценены 237 особей симментальской породы и помесей разной степени кровности по красно-пестрым голштинам (КПГ): 25—50%, 50—75% и выше 75%. Оцениваемыми признаками являются форма вымени и сосков, среднесуточный удой, время доения, интенсивность молокоотдачи. Установлено, что среднесуточный удой в группе коров с кровностью 25—50% по КПГ достоверно (Р<0,01) превышал этот показатель у чистопородных симменталов. Время доения в этой группе (12,23±0,21 мин) было достоверно меньше, а интенсивность молокоотдачи (1,9±0,03 кг/мин) достоверно (Р<0,01) выше по сравнению с чистопородными животными. По величине среднесуточного удоя между коровами с ваннообразной и чашеообразной формами вымени не выявлено достоверных различий, коровы с ваннообразным выменем достоверно (Р<0,05) превосходят особей с округлым выменем. Установлено, что все изученные признаки пригодности к машинному доению достоверно коррелируют друг с другом, что требует обязательного использования хотя бы одного из них при селекционной работе. Коэффициент корреляции между среднесуточным удоем и временем доения колебался от 0,416 до 0,603 во всех исследуемых группах. Взаимосвязь между суточным удоем и скоростью доения варьировала от 0,316 до 0,758. Ее показатели были значимыми при Р<0,01 во всех исследуемых группах. Между среднесуточным удоем и скоростью доения выявлена положительная связь, которая меняется от сильной до почти слабой с увеличением кровности по КПГ. To characterize the suitability for machine milking of cows of different pedigree in the Simmental breed in the Volga region we evaluated 237 cows of Simmental breed and crossbreeds of different blood streak by red and white Holstein: 25—50%, 50—75% and above 75%. The udder and teat shape, daily milk yield, time of milking and intensity of milk yield were evaluated. It was established that the average daily milk yield in the group of cows with blood 25—50% by Holstein was significantly higher than that in the group of purebred Simmental cows (P<0.01). The milking time in this group (12.23±0.21 min) was significantly shorter, and the milking intensity (1.9±0.03 kg/min) was significantly higher in comparison with purebred cows (P<0.01). There were no significant differences in the average daily milk yield between the cows with bowl-shaped and tub-shaped udders, the cows with tub-shaped udders significantly exceeded the cows with round udders (P<0.05). It was found that all the studied traits of suitability for machine milking significantly correlate with each other, which requires obligatory use of at least one of them in selection work. The correlation coefficient between the average daily milk yield and time of milking ranged from 0.416 to 0.603 and the correlations were significant in all the groups. In our study, the correlation between daily milk yield and milking rate ranged from 0.316 to 0.758, its values were significant at P<0.01 in all groups under investigation. Positive correlation between average daily milk yield and milking rate was found in all studied groups; however, it varied from strong to almost weak with the increase of the blooding rate.

Khabarovsk Federal Research Center of the Far Eastern Branch of the Russian Academy of Sciences Far Eastern Research Institute (KhFRC FEB RAS FIARI)Features of tomato breeding in the Amur region. Results and perspectives

Relevance. Khabarovsk region is considered to be the zone of risky agriculture. It is characterized by the monsoon climate (july - september), having no analogies in Russia by univen distribution of precipitation, temperature drops and high natural infections background. That is why the search of tomato sorts, responsive to environmental changes, with increased or stable yield is highly relevant. The aim of our perennial researches in the creation of highly productive sorts and hybrids of tomato, most fully realizing natural and climatic conditions of cultivation, having higher stability to the most harmful diseases, stress environmental factors and high productive potential. The most significant limiting factors when growing tomatoes in the region are high natural infections background and sharply variable hydrothermal regime, formed under the influence of the Priamurye monsoon climate.Methods. The selection work had been made on vegetable plot of DV NIISH. The seedlings had been growing by cassette method into film greenhouse, which had been no had heating. Then the seedlings was planted out into open ground in accordance with bed technology recommended in the region by scheme 140 X 35 cm. The main method of selection work of new tomato sorts creation was analytical with continious selection. All the necessary phenological, biometrical and psychopathological observations and accounts had been done by generally accepted methodics.Results. The results in development of tomato selection in DV NIISH was the creation of sorts with different ripening time: early ripe – Zarya Vostokа and middle ripe – Amursky Utios and Dunyasha. They were included in the State registry of selection achievements in 2008 year. Sorts Klad and Galant passed successfully the state sort tests and were included in the state registry of selection achievements in 2017 and 2018 years. All these sorts are recommended for growing in garden plots, private plots and farms.

Relationship between life of mate butterflies and leading selection characteristics

This article examines the history of silkworm breeding, the role of silkworm breeding in the national economy of the Republic of Uzbekistan and the role of silkworm breeding in the development of the industry. This is because the interrelationship of traits of economic value is of great importance in selection and breeding work. The experiments were conducted in 2015-2017 at the Silk Research Institute of Uzbekistan. The life expectancy of the experimental butterflies was 10.9-12.8 days and the variability was 33.9-56.6%. The coefficient of variability indicates the degree of diversity in the population on this trait. Thus, it is clear from the results that the population of “Marvarid” and “Liniya 27” has the ability to carry out selection work on the sign of life expectancy of female butterflies.
