摘要

CO481是一种早熟(57-58天开花，1283-1310个作物热量单位)的黄色半塌陷自交系。CO481具有混合杂种群，与刚性茎秆试验体结合良好，可生产出高产杂交种。CO481的其他主要特性包括快速的谷粒干燥率和对赤霉素穗腐病的中高抗性。CO481最适合北美短季地区，CHUs范围为2500至2750。这些地区包括加拿大的爱德华王子岛玉米种植区、安大略省东部地区以及魁北克省、马尼托巴省和阿尔伯塔省南部地区。

CO481 corn inbred line

CO481 is an early maturing (57–58 days to flowering, 1283–1310 crop heat units (CHUs)) yellow, semi-dent inbred line. CO481 has mixed heterotic group and combines well with stiff stalk testers to produce hybrids with high grain yield. Additional key features include fast kernel drydown rate and moderate to high resistance to gibberella ear rot. CO481 is most suitable for short-season regions of North America with CHUs ranging from 2500 to 2750. These include the corn-growing regions of Canada in Prince Edward Island, eastern parts of Ontario, and southern parts of Quebec, Manitoba, and Alberta.

期刊介绍： Published since 1957, the Canadian Journal of Plant Science is a bimonthly journal that contains new research on all aspects of plant science relevant to continental climate agriculture, including plant production and management (grain, forage, industrial, and alternative crops), horticulture (fruit, vegetable, ornamental, greenhouse, and alternative crops), and pest management (entomology, plant pathology, and weed science). Cross-disciplinary research in the application of technology, plant breeding, genetics, physiology, biotechnology, microbiology, soil management, economics, meteorology, post-harvest biology, and plant production systems is also published. Research that makes a significant contribution to the advancement of knowledge of crop, horticulture, and weed sciences (e.g., drought or stress resistance), but not directly applicable to the environmental regions of Canadian agriculture, may also be considered. The Journal also publishes reviews, letters to the editor, the abstracts of technical papers presented at the meetings of the sponsoring societies, and occasionally conference proceedings.
