中国北部高原地区谷子(粟)品种高产稳产性的评价

 利用回归系数法、稳定性参数法和高稳系数法 ,对我国北部高原地区新育成的 18个新品种 (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 ,占 5 5 .5 % ,但其中产量稳定性较差的占多数 ,高产稳产的品种较少 ,仅有铁 93- 115、95汾选 3和承谷 8号 ,占 16 .7% ,其余的均为低产稳产和低而不稳的类型 ,各占 2 2 .2 %。这可能与品种性状的适应性有关

Evaluation on High and Stable Yield Ability of Foxtail Millet in the North High Plateau Area in China

The high and stable yield abilities of 18 millet varieties which have breed recently for the north high plateau area in China were studied by the methods of megression coeffient, stable parameter, and high and stable yield coefficient as well. The results showed that the most of the test varieties had high yield, which was 55.6%, but in which they had poor stability so that there was only three varieties as Tie93 115,95 Fenxuan 3 and Chenggu 8 with high and stable yield ability, which was 16.7%. The others were the low and stable yield or the low and unstable yield varieties, which was 22.2% respectively.
