八、品种稳定性参数估测的计算程序对于育成的新品种或从国外引入的品种能否广泛种植,需要研究不同环境条件下的品种稳定性。为此要进行一年多点或多年多点的区域性试验,或者在同一地点创造不同的环境,即将试验材料按不同播期、不同株行距、不同施肥量、不同灌水量的条件进行 Calculation Procedure for Parameter Estimation of Variety Stability It is necessary to study the stability of breeds under different environmental conditions for the possibility of planting a wide variety of new breeds or varieties introduced from abroad. To do this multi-year or multi-year multi-year regional test, or in the same place to create a different environment, the test material by different sowing dates, different spacing, different fertilization rates, different irrigation conditions
