抗旱高产优质小麦新品种长6878选育研究

Selection of Chang 6878,a New Wheat Variety of Drought Resistant,High Yield and Fine Quality

以抗逆性强、丰产潜力大、稳产适应性广、优质专用为育种目标;广泛搜集、鉴定和利用黄淮和北部两大冬麦区的优异种质,使两大麦区的优异基因得以融汇;根据性状互补和累加的亲本配制原则,筛选和利用适用于当地推广应用的品种作为中心亲本,使目标性状得到有效组合;后代采用水旱地交叉选育法,使杂种基因型的各种性状得以充分表达,提高了选择效率,加快了选育进程,使育成品种长6878表现抗旱高产、稳产广适、品质优良、综合农艺性状好。

The breeding goals are high hardiness,great yield potentiality,stable yield,wide adaptability,fine quality and special usage.Super quality wheat germplasm have been collected,identified and utilized in two winter wheat regions of Yellow River and Huaihe,and northern China to realize the mixture of the fine genes;Based on parent allocation principle of trait complementary and accumulation,local variety were applied as center parent in our selection and extension to get effective combination of goal traits.Their posterities were cross selected in irrigated or dry land on the purpose for all traits to get full express and to improve selection effect and accelerate selection.Chang 6878 is such a new variety of drought-resistant,high-yield,stable and wide adaptation,fine-quality and good integrated performance.
