新疆喀什地区适栽抗除草剂复播谷子品种筛选初报

Preliminary Report on Selection of Herbicide-Resistant Foxtail Millet Varieties Suitable for Planting in Kashgar,Xinjiang

对来自不同生态区谷子品种的农艺性状与产量性状进行相关分析,探讨主要农艺性状对产量的影响,挖掘适宜南疆地区复播的早熟、高产、优质抗除草剂谷子新品种。2019-2020年以不同生态区的13个主推谷子品种为材料,采用相关性分析对产量相关的12个农艺性状进行综合评价。结果表明,各品种生育期在78~109d,供试材料中6个品种生育期均≤88d(豫谷18,CK);有7个品种连续2年各综合性状表现优异,产量稳定,相比CK显著增产。穗重、穗粒重、成穗数与产量呈显著正相关;8个农艺性状对谷子产量影响依次为穗重>穗粒重>穗数>生育期>株数>穗粗>穗长>株高,说明抗除草剂复播谷子品种的筛选应首先关注穗部性状,其次是生育期与株高。通过综合评价,筛选出豫谷32、赤谷K1、冀杂金苗、豫谷31和冀谷41等5个较适宜在南疆地区推广种植的抗除草剂品种。

The correlation between agronomic traits and yield traits of foxtail millet varieties from different ecological regions were analyzed to explore the effects of main agronomic characteristics on yield,excavate new foxtail millet varieties suitable for resowing in southern Xinjiang with early maturity,high yield,high quality and herbicide resistance.In 2019-2020,13 varieties from different ecological regions were used as materials,using correlation analysis,twelve agronomic traits related to yield were comprehensively evaluated.The results showed that the growth period of each variety was between 78-109d,the six varieties tested had a growing period≤88d(Yugu 18,CK);seven varieties showed excellent comprehensive traits for two consecutive years,the yields was stable,and significantly higher than that of CK.Panicle weight,panicle grain weight and number of panicles were positively correlated with yield;the effects of eight agronomic traits on millet yield were panicle weight>panicle grain weight>number of panicles>growth period>number of plants>panicle diameter>panicle length>plant height,which indicated that panicle traits should be paid attention to in screening of herbicide-resistant foxtail millet varieties,followed by growth period and plant height.Through comprehensive evaluation,five herbicide resistant varieties‘Yugu 32’,‘Chigu K1’,‘Jizajinmiao’,‘Yugu 31’and‘Jigu 41’were selected to be suitable for planting in southern Xinjiang.
