Abstract

The paper presents the evaluation of the total combining ability of the seed parents of white sweet clover Melilotus albus and yellow sweet clover Melilotus officinalis based on leaf formation, forage productivity and seed productivity. The results of competitive heterosis for the yield of herbage, dry matter and seeds of the polycross offspring Syn1 are also presented. Among the polycross offspring Syn1 Melilotus albus, SGP-4-12507 and SGP-5-12508 were selected based on their leaf formation (50 and 50%, respectively); competitive heterosis was 16.3 and 22%, respectively. Based on the total combining ability of offspring Syn1 of Melilotus albus, the following biotypes were selected: SGP-2-12519 (27.1%) and SGP-1-12503 (20.8%) for forage productivity; SGP-4-12601 (14.7%) and SGP-5-12508 (13.0%) for dry matter productivity; SGP-4-12601 (50.4%), SGP-2-12519 (19.2%) and SGP-5-12508 (14.1%) for seed productivity. The highest total combining ability were found for the following biotypes of Melilotus officinalis: SGP-9-12454 and SGP-10-12455 for leaf formation (18.2 and 13.3%, respectively); SGP-10-12455 (12.5%) for herbage productivity; SGP-10-12455 (29.6%) and SGP-9-12454 (24.2%) for dry matter productivity; SGP-6-12520 (15.4%) and SGP-9-12454 (14.1%) for seed productivity. Selected sweet clover samples can be recommended as the best basic material for further work on selection for high forage and seed productivity.

The following Syn1 were selected among the Melilotus albus biotypes based on the leaf formation: SGP-4-12507 (50%) and SGP-5-12508 (50%)
It should be noted that herbage and dry matter productivity of these biotypes was higher than the productivity of other biotypes: The herbage productivity of SGP-4-12503 was 94.2 g per plant and hay productivity was 21.5 g per plant

Summary

Introduction

One of the global problems of mankind is food shortage. Growth of the total world population by an average of 2.5 billion (30-34%) is expected by 2050 and it will reach 9.1 billion. In this regard, the global goal is to increase production and provide humanity with high-quality environmentally safe products (Makkar et al, 2014). The development strategy for a cost-effective highquality food sector is based on a combination of two fundamental factors: High productivity of animal products through the use of high-protein feed and low cost of forage herbs (Baidalin et al, 2017)
