Wheat is one of the most important crops for human and the most widely grown crop.However, the amount of molecular markers available for marker-assisted selection is limited due to the declined geneti
Pre-harvest sprouting (PHS) in cereals (wheat and barley) is a worldwide problem resulting in yield loss and quality deterioration.It is very indispensable to perform wheat breeding against PHS around
小麦品种"矮抗58"由河南科技学院小麦中心主任茹振钢教授选育成功, 其系谱为周麦11//温麦6号/郑州8960.自2005年脱颖而出到迅速推广应用,目前已成为我国黄淮南部麦区大面积种植的小麦品种.
小麦是世界上大部分地区的主要粮食作物和食物来源.由布氏白粉菌(Blumeria graminis f.sp.tritici)引起的白粉病是小麦的一种重要叶部病害.它的流行严重影响小麦产量.抗病品种的培育和利用是控制该病害最为环保和经济有效的措施.
Recent advances in sequencing technologies bring us a deluge of genomes during the past few years, providing cost and time savings.However, lots of challenges are still ahead for plant community, beca
回顾从事小麦育种工作40年来的实践及主持育成12个国家审定和17个河南省审定小麦品种的体会.利用"六五"一"十五"河南省小麦生产统计和品种区试资料,分析了本省小麦产量变化及品种改良遗传进展及贡献率.
二十世纪80年代我国小麦连年丰收,而优质小麦依赖进口,选育面包小麦成为国家战略需求.为此,开展了小麦品质育种研究,确定了品质与产量协调提高的育种策略.提出选用农艺性状较好的优质亲本和品质较好的农艺亲本杂交,培育品质和产量超亲的亲本选配模式;挖掘和创新优质亲本;创新采用真空干燥法提高微量沉降值测定的精确性,解决了早代个体品质鉴定的技术难题,在此基础上制定出优质面包小麦品质鉴定程序和选择标准,实现了育
条件QTL分析是一种根据作物生长特定阶段或相关性状(措施)等给定条件下的净遗传效应,分析数量性状基因时空表达和互作效应的遗传分析方法.传统QTL(也称非条件QTL)定位一般基于性状终端(或阶段终端)的累积遗传效应值,而条件QTL基于给定条件的净增加效应值.
Wide or distant hybridization has been widely used as an important tool of chromosome manipulation for wheat improvement.The chromosome behaviors in hybrids provide us with the essential genetic basis
Wheat relatives are rich gene resources for wheat improvement.The introduction of the alien genes has been successful for improving the agronomic traits, particularly resistances to pests and diseases
