Comparative characteristics of breeding numbers of meadow clover Sakhalin population.
V.A. CHUVILINA (Sakhalin Research Institute of Agriculture, Yuzhno-Sakhalinsk).
In the conditions of the monsoon climate of the Sakhalin Region in the period of 2013–2016 in the nursery of
preliminary variety testing on the meadow-sod of old-cultivated soil, a comparative assessment was made of three
breeding numbers of meadow clover early maturing two-cuts type, obtained as a result of multiple mass selection. The
fodder productivity of breeding numbers in the amount of two mowing exceeded the standard Primorsky 14 variety
in collection from 1 hectare: green mass – by 37–64 %, dry matter – 30–65, raw protein – 38–80, feed units – 31–64
and exchange energy – by 37–72 % on average for 4 years of research. The average adaptability coefficient (Ka) was
maximum (1.10–1.37), exceeded the standard by 0.31–0.58 units, which indicates significant environmental sustainability.
