黑粉菌属tritici,宽松小麦黑穗病的因果代理(小麦L),属于家庭黑粉菌科。在自然界中,由黑粉菌属感染segetum var. tritici器官特定即通过卵巢,它是可能的,只有在相对比较短的花期的主机。在这个领域,有两种接种方法;干燥法和wetable法。一个广泛的工作已经完成在世界的许多国家,对于识别来源的抵抗疾病,因为育种阻力可能控制这种疾病最有效的方法之一。宽松的色情导致农艺charactesrs减少。收益率是一个行动和互动的终极产品定量特征,这是由不同的多基因控制。因此,ombining能力研究使用的植物育种者选择的父母最大传输子代的基因的潜力。结合能力的评估是非常有用的,因为由于一般配合力方差由加性基因行动,虽然由于特殊配合力方差是归因于非附加基因行动。杂种优势的产业可以帮助选择一些优越的父母和交叉组合育种计划进一步剥削农艺性状或抵抗植物病害和证明,抵抗是占主导地位的敏感性。 The results indicated at least one major gene and one minor gene segregation for resistance and transgressive segregation for these parents differed in genes for resistance. Improvement of quality in wheat (Triticum aestivum L.) depends on the influence of environmental conditions and their interactions. Loose smut causes damage by destroying the infected plants and reducing the quality of grain of the non-infected plants upon harvest. Embryo test for detecting the dormant mycelia in the infected seeds has extensive importance, since a direct correlation was observed between the level of embryo infection and the incidence of loose smut in the field. It was stated that the total nitrogen content of the host- pathogen complex generally increased during the early stage of disease. Increase in secreted protein play important role during pathogenesis and thought to act as effectors for modulating the plant response. Fungus penetration and growth through cells as well as disintegration of plant cell wall at later stages requires lytic enzymes.
