Introduction Identification and Variety Characteristic Analysis of New Hexaploid Triticale Variety T-133
摘要
Abstract
Triticale is a new species formed by cross between wheat and rye.Compared with wheat and rye,triticale has higher biological yield,protein and lysine content,and better palatability.It can be used as a high-quality grass forage to promote the diversified development of forage grass.To further diversify the forage varieties in Gansu,the hexaploid triticale T-133 was introduced from CIMMYT in 2013,it was bred by flood and drought identification test,variety comparison and production test from 2014 to 2020.Data from the production experiments in different ecological zones in 2020 shows that the average grain yield is 7 814.94 kg/ha,which is 17.45%higher than the control variety Ningchun 4.The average biological yield is 22.39 t/ha,which is 12.92%higher than the control variety Shida 1.This variety is a grain-grass type with spring character.The growth period is 100 to 109 days,the plant height is 115 to 120 cm,the spike length is 10.0 to 10.5 cm,the number of spikelet is 21 to 24,the kernels per spike is 45 to 50 and the thousands-kernels weight is 47 to 56 g.The grain is rich in iron,zinc and other trace elements,it is strong resistance to disease with premium characters.It is suitable for cultivation in Hexi,Central region in Gansu,Qinghai,Ningxia and other high and arid regions with similar ecological conditions.关键词
