SummaryRice is the staple crop of Guinea Bissau, and its production system is based on human labor with very limited possibility of mechanization, particularly in the Mangrove ecosystem. Due to this and to the low possibilities of controlling environment parameters, such as water level and availability, the genetic resistance to extreme abiotic factors was identified as a key point for increasing yields quantity and stability. Among the ample genetic material available in the country, no purification activities were carried out in the past decades. This led to the cultivation of mixtures or ecotypes and not to uniform varieties, with consequent issue related to cultivation and milling. On 103 samples collected, only on about 50% of ecotypes, the purification was carried out as the remaining half was too much variable. The purification ended with less than 20% of material considered stable and uniform varieties. Moreover, the program adopted a bottom-up approach for collection and variety conservation to drive the program and improve the genetic material.

几内亚比绍的红树林水稻生物多样性增值。自下而上的方法
摘要水稻是几内亚比绍的主要作物,其生产系统以人工为基础,机械化的可能性非常有限,尤其是在红树林生态系统中。由于这一点以及控制环境参数(例如水位和可用性)的可能性较低,对极端非生物因素的遗传抗性被确定为增加产量和稳定性的关键点。在该国现有的丰富遗传材料中,过去几十年没有进行任何纯化活动。这导致了混合物或生态型的种植,而不是统一的品种,随之而来的问题与种植和碾磨有关。在收集的 103 个样本中,仅对大约 50% 的生态型进行了纯化,因为剩下的一半变化太大。纯化结束时,只有不到 20% 的材料被认为是稳定且均匀的品种。此外,该计划采用自下而上的收集和品种保护方法来推动该计划并改进遗传材料。
