不同小黑麦种质在甘肃中部地区的农艺性状比较
Comparative on agronomic traits of different triticale germplasm in central Gansu Province
【摘要】 【目的】比较分析甘肃中部地区不同小黑麦种质的农艺性,筛选出在甘肃兰州地区农艺性状较好的小黑麦种质。【方法】分别测定6种参试小黑麦种质,测定小黑麦种质田间形态特征(株高、枝条数、叶片数)和单株地上生物量,并进行统计分析。【结果】C25株高最高(154.27 cm),但其叶片数较少(57.6个/株),枝条数最少(10.47个/株);藏饲1号株高(143.15 cm)次之,但枝条数较多(11.9个/株),叶片数较多(64个/株),单株地上生物量最高(80.79 g);甘农7号枝条数最多(13.82个/株),但其前期株高增长缓慢;甘农4号分蘖性能优异(12.49个/株),叶片数最多(69.7个/株),但叶片数最少(54个/株)。【结论】藏饲1号小黑麦种质在甘肃中部地区农艺性能较好。
【Abstract】 【Objective】The aim of the experiment was to compare the agronomic traits of 6 kinds of triticale germplasm(Gannong 4,Gannong 7,C5,C23,C25) and to select the better germplasm with good agronomic characters in Lanzhou,Gansu Province. 【Method】The field morphological characteristics(plant height,number of branches,number of leaves) and aboveground biomass per plant were measured and statistically analyzed.【Result】The height of C25 was the highest(154. 27 cm),but the number of leaves was less(57. 6/plant) and the number of branches was the least(10. 47/plant). Zangkai No. 1 had the second highest height(143. 15 cm),but more branches(11. 9/plant),more leaves(64/plant),and the highest above-ground biomass per plant(80. 79 g/plant). Gannong No. 7 had the largest number of branches(13. 82 per plant),but the growth of plant height in the early stage was slow.. Gannong No. 4 had excellent tillering performance(12. 49 per plant),the highest number of leaves(69. 7 per plant),but the lowest number of leaves(54 per plant).【Conclusion】Zangkai No. 1 had better agronomic performance in the central region of Gansu Province.
