不同基因型冬小麦产量性状和品质性状表现

The Performance of Yield and Quality Characters of Different Winter Wheat Genotypes

[目的]初步筛选适合宁夏种植的冬小麦新品种。[方法]对9个冬小麦品种进行品种比较试验,观察参试品种的产量性状和品质性状。[结果]品冬8号的产量最高,比对照5088增产24.78%,然后是品冬2号和6号,分别比对照5088增产18.26%、16.48%。宁冬6号和品冬2号略早熟,落黄熟相较好。品冬8号、6号和2号的灌浆速度快。品冬5号的湿面筋含量稍低。参试品种(系)的沉降值差异很大,品冬2号和4号的沉降值、蛋白质含量均最高,沉降值分别为52.62、50.72ml,蛋白质含量分别为16.62%、16.49%。品冬2号的硬度最高,为53.88。[结论]品冬8号、2号和6号可继续参加宁夏区域试验,进行进一步鉴定。

[Objective] The study aimed to preliminarily screen new wheat varieties （lines） suitable to be planted in Ningxia. [Method] Nine varieties of winter wheat varieties （lines） were made for the comparative test to observe their yield and quality characters. [Result] Pindong 8 had highest yield, increasing by 24.78% than CK 5088, followed by Pindong 2 and 6, increasing the yield by 18.26% and16.48% resp. than CK 5088. Ningdong 6 and 2 were slightly early and better in maturing phase. Pindong 8, 6 and 2 were faster in filling rate. Pindong 5 was slight low in wet gluten content. There was a great difference on sedimentation value among the tested varieties （lines） and the sedimentation value and protein content of Pindong 2 and 4 were all highest, with their sedimentation value being 52.62 and 50.72 ml and the protein content being 16.62% and 16.49%.The hardness of Pindong 2 was highest, being 53.88. [Conclusion] Pindong 8, 2 and 6 could continue to join the regional test in Ningxia for further identification.
