适宜丘陵旱薄地谷子新品种适应性评价

为筛选适宜丘陵旱薄地种植的谷子新品种，在山西省3 个试验点连续2 年种植本单位自育的9 个谷子新品种，以‘晋谷21 号’为对照，分析比较了不同试验点参试品种表型性状及产量年际间的变化差异。结果表明，左权县试验点4 个测验指标年际间变化没有达到显著水平，榆次区年际间差异仅产量达到显著水平，盂县除株高外，其他性状均达到极显著水平(P>0.01)，且2012 年指标数值高于2013 年；参试品种的株高和穗长在3 个试验点差异显著，榆次区参试品种的平均株高最高（2013 年169.5 cm；2012年162.1cm），左权最低（2013 年123.8 cm；2012 年117.9 cm）；榆次区2013 年平均穗长最高(24.4 cm)，盂县2013 年穗长最低(14.3 cm)。另外，不同谷子新品种在不同地区的适应性不同，而且各试验点新品种产量水平均高于当地主推品种‘晋谷21号’。

Adaptable Evalution of New Millet Varieties in Arid and Low Production Hilly Regions

In order to select varieties of millet for arid and low production hilly regions, 9 varieties of millet, which were breed in Shanxi Academy of Agricultural Sciences, were planted in 3 arid and low production hilly regions of Shanxi Province for 2 consecutive years, the variety of‘Jingu 21’was planted as control. The phenotypic traits and yield of all varieties in different test points were compared. The results showed that annual variability of four indexes did not reach a significant level in Zuoquan. The phenotypic traits did not reach a significant level except production in Yuci. Moreover, the characters of all the varieties in Yuxian reached a significant level except height （P〉0.01）, and the indicator of 2012 was higher than that of 2013. The plant height and ear length of all varieties in three pilot sites were significantly different, the average plant height in Yuci was the highest （2013：169.5 cm;2012：162.1 cm）, the pant height in Zuoquan was the lowest （2013：123.8 cm;2012：117.9 cm）;the average ear length in Yuci was the longest （24.4 cm）, the ear length in Yuxian was the shortest （14.3 cm）. Different new varieties of millet in different regions were different, and the production of new variety was higher than that of the local variety‘Jingu 21’.
