VALUE OF REPRODUCTION COEFFICIENT IN PRODUCTION OF SEEDS OF SPRING BARLEY VARIETIES

In seed production, reduced seeding rates are often used for accelerated propagation of varieties, since the number of seeds may be limited. To assess the effectiveness of such a technique, the seed multiplication coefficient is calculated (the ratio of the mass of collected seeds to the mass of sown seeds). In our experiment, this indicator was higher (34.6) with a reduced seeding rate of barley - 3.5 million grain crops per ha.
