新疆狗牙根农艺性状及利用价值初探

对新疆具有代表性的7份狗牙根Cynodon dactylon材料的12项农艺性状进行初步研究表明,新疆狗牙根种内差异大,具有培育优良新型牧草或草坪品种的潜力,其中C5植株高大、茎秆粗壮、叶片大、草产量高,C1植株矮小、茎秆及叶片纤细、颜色深绿,其余材料居中;通过农艺性状聚类分析,结合加权综合评价结果,初步将新疆狗牙根划分为3个类型,即草坪草牧草兼用型(包括喀什狗牙根、新农一号狗牙根、C4、C3)、草坪型(C1、C2)、牧草型(C5),为今后新疆狗牙根种质资源的进一步开发利用提供科学的依据。

Preliminary Study on agronomic characteristics and evaluation of native Bermudagrass resource in Xinjiang

Twelve agronomic characters of seven representative bermudagrass in Xinjiang were studied.Result showed:variation of Xinjiang bermudagrass was great,most of them were suitable to be used for forage or turfgrass with great potential that they could be cultivated into new varieties.Among them,C5 has the trait of high and strong stalk,big leaf,high yield;C1 has the trait of low and slim stalk,fine leaf;other materials lay in the middle.By cluster analysis and comprehensive evaluation,they could be divided into three different types,i.e.,forage and lawn type including Kashi bermudagrass,Xinnong No.1 bermudagrass,C4,C3;lawn type including C1,C2;forage type including C5.This study could provide as a reference for further utilization of Xinjiang bermudagrass germplasm resource.
