吉林省西部干旱地区优质谷子品种筛选

Millet Varieties Selection for Arid Area in the Western Part of Jilin Province

为了筛选出适合吉林省西部地区生产上应用的谷子品种,试验以近年来培育出的19个优质谷子品种或品系为试验材料进行品比筛选,通过调查各项指标数据,用DPS软件进行比较分析。结果表明,比对照品种九谷11增产的品种有10个,产量最高的品种嫩选18,比对照增产12.28%,中谷2次之,比对照增产11.87%,其他增产品种依次为保928、赤谷29、豫谷35、九谷32、冀谷43、豫谷38、公谷84、公谷86。根据株高,可供选择应用的稳产、高产、中高杆良种为嫩选18、冀谷43、豫谷35、豫谷38、保928,矮秆良种为公谷86、中谷2、九谷32、公谷84,抗倒伏能力强。本试验鉴定筛选出适应性好、高产稳产的品种有嫩选18、中谷2、保928、豫谷35、九谷32、公谷86,与对照相比增产极显著;株高为中高杆或矮秆品种,适合机械化、轻简化种植,建议在吉林省西部及相似生态区优先推广种植。

In order to select millet varieties for the western part of Jilin province, 19 millet varieties bred in recent years were planted in random block arrangement with 3 repetitions for species by DPS. The results showed that the yield of 10 varieties were higher than that of Jiugu 11(ck). The yield of Nenxuan 18 was the highest, increased 12.28% than ck. Zhonggu 2 was the next, increased 11.87% than ck. Other yield increasing varieties were Bao 928, Chigu 29, Yugu 35, Jiugu 32, Jigu 43, Yugu 38, Gonggu 84 and Gonggu 86 in turn. The medium and high stem varieties with stable and high yield were Nenxuan 18, Jigu 43, Yugu 35, Yugu 38 and Bao 928, and the short stem varieties with strong lodging resistance were Gonggu 86, Zhonggu 2, Jiugu 32 and Gonggu 84. In this experiment, Nenxuan 18, Zhonggu 2, Bao 928, Yugu 35, Jiugu 32 and Gonggu 86 were selected as appropriate varieties with high and stable yield. The varieties with medium and high stem suitable for mechanized and lightened and simplified cultivation were recommended to extend as priority.
