Comparative Experiment of 5 New Quinoa Varieties in Cold and Arid Mountainous Areas
摘要
Abstract
This study aimed to breed suitable quinoa varieties for cultivation in Tianzhu Zangzu Autonomous County of Wuwei City,providing data for the selection of quinoa varieties in Tianzhu and expanding income channels for farmers.Using Longli 1 and Longli 5 as controls,the growth,yield,and quality of 5 new quinoa varieties in the Tianzhu area were compared and analyzed.Results indicated that all 5 quinoa varieties could mature normally,with a growth period ranging from 130 to 139 days.There were varying degrees of differences in characters such as plant height,stem diameter,ear shape,leaf shape,and seed color among the different varieties.Among them,2068-10,2068-12,and 2068-13 had distinct superior characteristics with growth periods(130,134,139 days),plant heights(177.0,200.0,169.6 cm),stem diameters(17.3,16.3,16.3 mm),and 1000-grain weights(3.42,3.36,3.68 g)performed ideally.The quinoa variety 2068-13 showed the highest yield of 5 090.55 kg/ha,an increase of 20.9%over the control variety Longli 1 and an increase of 135.1%over Longli 5.The yield of 2068-10 was 4694.55 kg/ha,showing an increase of 11.50%over Longli 1 and 116.81%over Longli 5.Analysis of quality revealed that 2068-10 had the highest moisture and ether extract contents,2068-12 had the highest protein and crude fiber contents,and 2068-13 had relatively high crude fiber content.In conclusion,2068-10,2068-12,and 2068-13 perform well in Tianzhu Zangzu Autonomous County,Wuwei City,and could be promoted for cultivation in this region and other similar ecological zones.关键词
