【摘要】 利用回归系数法、稳定性参数法和高稳系数法 ,对中国北部高原地区新育成的 18个谷子品种 (系 )的高产稳产性进行了研究。结果表明 ,参试品种多数产量较高 ,约占 55 6 % ,但其中产量稳定性较差的占大多数 ,高产稳产的品种较少 ,仅有 95汾选 3、铁 93- 115和承谷 8号 3个 ,约占16 7% ,其余的均为低产稳产和低而不稳的类型 ,大约各占 2 2 2 %。这可能与品种性状的适应性有关更多还原

【Abstract】 The high and stable yield ability of newly bred 18 millet varieties for the north plateau area in China were studied by the methods of regression coefficient, stable parameter, and high and stable yield coefficient. The results showed that the most tested varieties (55.6%) had high yield, but not stable. Only three varieties (16.7%) Fengxuan 3, Tie 93-115, and Chenggu No.8 gave high and stable yield. The others (22.2%) were either low and stable yield or low and unstable yield varieties. This was due to the adaptability of the varieties.更多还原
