杂交玉米新品种兴海201高产制种技术

High-yielding Seed Production Techniques of Hybrid Maize Xinghai 201

兴海201是贵州省黔西南州农业科学研究所1999年利用自育自交系WX213346×S3241组配而成的黄粒玉米单交种,结合多年的制种经验及兴海201在亲本繁殖、杂交种生产中所做的密度、行比、施肥配方等多项研究,阐述了亲本繁殖中原种生产、生产要求、自交系良种生产及杂交种生产中选地、隔离,规格种植、增加密度,科学施肥、合理用水,去雄去杂质量,适时收获、及时晾晒等获得高产的各个关键技术点。

Xinghai 201 is an interlinear hybrid maize, which was crossed by female parent WX213346 and introduced male parent $3241 in 1999. According to the many years＇ practice, planting density, spacing ratio, fertilization of Xinghai 201 in parent breeding, hybrid seed productiont was studied, and reviewed protospecies production, inbred line productom, land selection, land isolating, planting spacing, increase planting density, fertilization, water management, hybrid seed, seed purification, on timely harvest and etc in hybrid seed production.
