灰色系统理论在玉米新品种综合评价中的应用

INTEGRATED EVALUATION OF NEW CORN HYBRID STRAIN WITH THE THEORY OF GRAY-SYSTEM

应用灰色系统理论关联度分析法综合评价了9个中早熟组玉米新品种（或品系）。该方法避免了以往品种试验中单独以产量为标准进行品种评估的局限性，尝试将熟期、抗病性、抗逆性等重要农艺性状与产量共同进行量化处理，以得到较完整系统的试验信息，对试验品种做出更加科学的评价。

This thesis integrated evaluates 9 corns hybrids strains with the degree of the association analytical method of gray-system. The method avoids the limitations as a standard to breed evaluation. It attempts to use varies important agricultural characters such as mature stage, disease resistance, adverse resistance and also the yield to synthesize analyse. It is expect to get the experiment information more integrated, systematic and evaluated the experimental result more scientific and rational.
