务实地,水稻L. 是世界上最重要的食物,约有 30 亿人以大米为生,大米是整个东南亚的主食。不幸的是,病虫害仍然是显着限制水稻生产的关键生物胁迫。由于各种生物胁迫因素导致约 52% 的水稻产量下降的巨大不满。在生物胁迫因素中,褐飞虱(BPHs)是主要问题,这种破坏性害虫导致大量产量损失。事实上,过去已做出重大努力来开发针对不同害虫的抗性品种,特别是具有已确定抗性基因的褐飞虱。在这样的氛围中,大多数已开发的品种已经失去了抵抗力,导致更频繁和更严重的害虫爆发。因此,再次开始从现有的大量种质资源中寻找不同害虫抗性品种的新抗性供体。在这种情况下,分子标记辅助基因选择将提供有关抗性基因存在和不存在的信息。它可用于各种生物胁迫抗性育种计划,以改良广谱害虫的抗性和易感品种。该研究发现,在流行品种中识别和堆叠广谱抗性基因/QTL是任何有利于稻农的水稻育种计划的首要想法。再次开始从现有庞大的种质资源库中寻找不同害虫抗性品种的新抗性供体。在这种情况下,分子标记辅助基因选择将提供有关抗性基因存在和不存在的信息。它可用于各种生物胁迫抗性育种计划,以改良广谱害虫的抗性和易感品种。该研究发现,在流行品种中识别和堆叠广谱抗性基因/QTL是任何有利于稻农的水稻育种计划的首要想法。再次开始从现有庞大的种质资源库中寻找不同害虫抗性品种的新抗性供体。在这种情况下,分子标记辅助基因选择将提供有关抗性基因存在和不存在的信息。它可用于各种生物胁迫抗性育种计划,以改良广谱害虫的抗性和易感品种。该研究发现,在流行品种中识别和堆叠广谱抗性基因/QTL是任何有利于稻农的水稻育种计划的首要想法。它可用于各种生物胁迫抗性育种计划,以改良广谱害虫的抗性和易感品种。该研究发现,在流行品种中识别和堆叠广谱抗性基因/QTL是任何有利于稻农的水稻育种计划的首要想法。它可用于各种生物胁迫抗性育种计划,以改良广谱害虫的抗性和易感品种。该研究发现,在流行品种中识别和堆叠广谱抗性基因/QTL是任何有利于稻农的水稻育种计划的首要想法。

Rice: Nilaparvata lugens Stal interaction—current status and future prospects of brown planthopper management
Pragmatically, Oryza sativa L. is the most considerable food in the world and about 3 billion people rely on rice for their living sustenance and rice serves as a staple food across South East Asia. Unfortunately, the diseases and insect pests remain as the key biotic stresses limiting rice production significantly. The great dissatisfaction that about 52% of rice productivity is declined due to various biotic stress factors. Among the biotic stress factors, brown planthoppers (BPHs) are the major issues, and this destructive insect pests lead to extensive yield loss. As a matter of fact, significant efforts have been taken in the past to develop resistant varieties against different pests, particularly brown planthopper with identified resistant genes. In such an atmosphere, most of the developed varieties have lost their resistance resulting in more frequent and severe pest outbreaks. Consequently, again the search has begun for new resistant donors of different pest’s resistance cultivars from the existing vast germplasm collection. In this context, molecular marker-aided gene selection will provide information about the presence and absence of resistance genes. It can be utilized in various biotic stress resistance breeding programs for the improvement of the broad spectrum of insect pest’s resistant and susceptible varieties. The study has found that identifying and stacking broad-spectrum resistant genes/QTLs in the popular cultivar is the foremost idea of any rice breeding program which will benefit rice farmers.
