Evaluation of mulberry varieties by initial phenological phases as a tool to increase the productivity of silkworm feeders

Relevance. The mulberry gene pool of the RS Sericulture — branch «The North Caucasus FARC», is located in areas with various mechanical composition soils. Monitoring and screening a priority work station to preserve general collection, select varieties for feeding silkworms order improve base sericulture. Methods. research was carried out on plantations Station. object research: two fodder Georgia PS-109, which have high productivity potential silkworm rearing. evaluation according phenological phases development, yield leaves silk products, statistical data processing method O.V. Yanzer, E.Yu. Terentyeva, forage testing Caucasus-1 breed A.A. Klimova. Results. A comparative description initial vegetation Gruziya PS-109 growing that differ soils presented. Different dynamics leaf development has been established same variety from different areas. It mathematically proved uneven blade sites reduces required quality by 19.6%, 28.4%. Preliminary assessment based makes it possible assess volume sheet pre-feeding period ensure feeds.
