糜子分子遺傳研究進(jìn)展與展望
摘要:糜子是最古老的馴化栽培作物之一,具有抗旱、耐瘠、水分利用效率高、營養(yǎng)豐富等特點,在北方旱作農(nóng)業(yè)區(qū)特色糧食生產(chǎn)中占有重要地位。為深入推動糜子農(nóng)藝、產(chǎn)量及品質(zhì)相關(guān)性狀遺傳解析,在介紹國內(nèi)糜子遺傳研究現(xiàn)狀基礎(chǔ)上,通過文獻(xiàn)分析綜述了糜子分子遺傳研究進(jìn)展,并展望了未來發(fā)展趨勢。

Abstract: Broom corn millet (Panicum miliaceum L.) is one of the most ancient crops domestically cultivated in the world, it possesses characters of drought resistance, barren-tolerance, high efficiency in water utilization and dense nutrients which plays an important role in the characteristic grain productionin northern dryland zone. To further promote the genetic analysis of correlated characters in agronomy traits, yields and nutrients of broom corn millet, based on thedomestic research status of broom corn millet genetics, advances in molecular genetics of broom corn milletwerereviewed and prospect was made in this paper.
