Progress in rye breeding and its practical utilization in production in Poland in the years 1986–2000
Abstract
In last years many new high yielding population and hybrid varieties appeared on the market. In the paper effects of rye breeding and their practical utilization were estimated. The estimation was conducted by the method of changing yield potential of varieties. In conditions of varietal tests, in the period 1986–2000, the average yields of rye increased by 26 kg/ha/year as an effect of breeding. Potential effects of plant breeding on seed production and in merchandise production on farms were 4.3 and 2.6 kg/ha respectively. Practical utilization of the plant breeding effects is even lower, additionally limited by a low level of agricultural technology on farms. One of the main reasons of unsatisfactory breeding impact on the production level is an increasing dissonance between the breeding effects and the level of supply with seed of new varieties.
