Study on production performance and nutritional quality of triticale cultivars in northwest Henan region
The study aims to select high-yielding and high-quality triticale cultivars that are well-suited for cultivation in northwest Henan region through an evaluation of six triticale varieties(Triticosecale wittmack)in terms of forage production,quality,seed yield,and composition factors.The findings indicated noteworthy disparities among the tested varieties concerning forage production,nutritional quality,and seed yield.Notably,the'GN2'cultivar exhibited the highest hay yield(21.49 t/hm2),number of branches(9 330 500/hm2),and crude protein content(11.86％).Furthermore,'ZS1257'demonstrated the highest seed yield(6.55 t/hm2)and spiked grain count(56.00 grains).The yield of triticale varieties showed an increasing and then decreasing trend with the increase in the number of tillers,it gradually decreased with the increase in the weight of individual leaves and stems.The contribution of related factors to the grain yield was in the following order:number of grains per ear＞thousand-grain weight＞number of tillers.The study indicates that through comprehensive evaluation,'GN2'ranks first and can be promoted as a forage-type triticale for planting in the northwest Henan region.
