Adaptability Evaluation of New Triticale Lines in the Arid and Semi-arid Area of Central Gansu
摘要
Abstract
This study aimed to investigate the adaptability of forage triticale(×Triticosecale Wittmack)in the arid and semi-ar-id area of central Gansu,and to provide technical support for its large-scale demonstration and promotion in this region.The growth period,yield,and nutritional quality of 5 new triticale lines,namely 20182,20185,201811,201812,and 201823,were compared and analyzed using grey relational grade analysis.Results showed that all 5 new triticale lines could safely overwinter and complete their growth period normally in the arid and semi-arid area of central Gansu,with growth periods ranging from 285 to 288 d.The fresh for-age yield of the tested lines ranged from 48.93 to 61.40 t/ha,and the hay yield ranged from 16.90 to 22.07 t/ha.Among them,the new line 201812 ranked first among all tested lines in both fresh forage yield and hay yield.The grain crude protein(CP),ether extract(EE),crude fiber(CF),acid detergent fiber(ADF),and neutral detergent fiber(NDF)contents of the tested lines were 94.6 to 115.2 g/kg,20.7 to 30.7 g/kg,299.3 to 380.0 g/kg,382.0 to 480.0 g/kg,and 530.0 to 673.0 g/kg,respectively.Among them,the new line 201812 had the highest crude protein content,a relatively high ether extract content of 26.6 g/kg,a relatively low acid detergent fiber content of 442.0 g/kg,and the lowest crude fiber and neutral detergent fiber contents,indicating the best forage quality compared with the other tested lines.Based on a comprehensive analysis of fresh forage yield,hay yield,nutritional indicators,and relative feeding value using grey relational grade analysis,the new triticale line 201812 showed the best overall performance and is suitable for plant-ing and promotion in the arid and semi-arid area of central Gansu.关键词
