Abstract
The article presents the results of research on the biology of willow-carrot aphid and evaluation of varieties and hybrids of garden carrot in the Bryansk region. The aim of scientific research was to study the biological characteristics of willow-carrot aphid - Cavariella aegopodii (Scop.) (Homoptera: Aphididae), the influence of weather and climatic conditions on the pest prevalence, the degree of plant population, as well as the evaluation of varieties and hybrids of garden carrot on the complex of economically valuable traits. It was established that the average daily temperature of 18°C and above contributed to the intensive pest infestation of carrot plants in the first decade of July. The peak of the number of willow-carrot aphids was noted in I-II decades of July. With the increase of temperature increased the fecundity of females of the aphid up to 60-70 larvae. In 2017-2018 detected relatively resistant varieties and hybrids of garden carrot – Minor, Marlinka, Nantskaya 4, Nadezhda F1with an average damage score of 1.0-1.17. The variety Shantena royal is marked with plants with an average score of 2.43, which characterizes the average resistance of the variety to damage. In the Bryansk region on the basis of "mass of roots" on average, over two years of research significantly exceeded the standard (variety Nante 4) Shantena 2461, Shantena Royal, Minor, Nante, Cupar F1, Nadezhda F1, Mars F1 by 6.2 - 37.1 per cent. On the basis of "marketable yield" varieties and hybrids of Mars F1, Cupar F1, Nadezhda F1, Shantena royal, Nante, Minor were distinguished. According to the results of biochemical analysis, a variety of Nante with a high content of carotene (185.1 mg/kg), dry matter (13.3%) and low nitrate accumulation (110.2 mg/kg) was isolated. During two years of research in the conditions of the Bryansk region, it was established that Minor, Nadezhda F1 combined relative resistance to willow-carrot aphids damage and were distinguished on the basis of “commercial yield”.
