AbstractThe breeding process,cultivation characteristics,and high yield cultivation techniques of maize variety Fengda 928 were summarized.This variety was developed by crossing the inbred line LP6WC (female parent) with FGK01(maleparent),resulting inanearly-maturing maize hybrid suitable for machine harvesting .In multi-year, multi-locationregionalanddemonstration trials,itexhibitedexcellntstabilityandbroadadaptability,withagrowth period of 128 days,plant height of 273.4cm,and1O00-grain weight of345.5g.The average yield inregional trials ranged from 12 180 to 13236kg/hm2 .It demonstrated strong lodging resistance,moderate resistance to stalk rot and head smut,and grain compositions of 4.05% crude fat and 73.35% crude starch. Key high yield cultivation techniques included:early sowing withsuffcient soil moistureata depthof 4-5cm; moderateplanting densityof 75000- 85 000 plants/hm 2 in Northeast and North China; fertilization based on organic manure combined with nitrogen, phosphorus,andpotassium,supplemented with boronto enhance yield; integratedpest,disease,and weed management, including pre-emergenceherbicideappication,insectcontrolatseedlingstage,stem borerpreventionatthebellstage, and leaf disease control during polination;and delayed mechanical harvest after the milk line disappearance to maximize yield and quality.This article provides a reference for the promotion and cultivation of this variety.
