Preliminary Report on the Introduction and Selection Experiment of Buckwheat in the Semi-arid Region of Gansu
摘要
Abstract
To identify buckwheat variety suitable for cultivation in the buckwheat production area of Huining County,enrich buckwheat variety types,and promote sustainable development of the buckwheat industry,20 introduced buckwheat variety were subjected to comparative experiment,and their major agronomic traits,yield,and quality were analyzed.Results showed that among the 10 sweet buckwheat varieties,Dingtianqiao 1 had the highest yield of 979.6 kg/ha,which was 40.31%higher than the average yield of the tested sweet-buckwheat variety.Its single-plant grain weight(5.83 g),crude protein content(156.13 g/kg),and total flavonoid content(5.56 mg/g)were all the highest among the tested sweet buckwheat variety.Among the 10 tartary buckwheat varieties,Dinkuqiao 1 had the highest yield of 1 861.5 kg/ha,89.10%higher than the average of the tested tartary buckwheat varieties.Its plant height(99.9 cm)and number of main-stem nodes(22.8)were the highest,its branch number(19.0),single-plant grain weight(7.75 g),and total flavonoid content(27.63 mg/g)were also relatively high.Datian 1 and Yuntian 1 had good overall traits and relatively high yields of 845.5 and 1 633.4 kg/ha,respectively.Datian 1 showed high total flavonoid content(4.26 mg/g)and ether extract content(22.96 g/kg),and its thousand-grain weight(41.86 g)was significantly higher than other tested sweet buckwheat varieties.Yuntian 1 had a higher starch content(795.67 mg/g)than other tested tartary buckwheat varieties and relatively high crude protein content(166.43 g/kg).In conclusion,Dintianqiao 1 and Dinkuqiao 1 can be recommended as preferred variety for demonstration and promotion in the temperate semi-arid region of Gansu and similar ecological zones.Datian 1 can be used as a large-grain specialized type,and Yuntian 1 as a high-starch specialized type for promotion in the same regions.关键词
