Abstract

ABSTRACT Rice production in Ghana is limited by low varietal choices, which puts farmers at a disadvantage in meeting the market demand for consumers. The objectives of this study were to (i) assess the yield potentials of improved rice varieties developed by the Africa Rice Center (AfricaRice), and (ii) to allow farmers to select improved varieties of their choice based on growth and yield, as observed in the field, in order to ensure a high adoption rate, increase productivity and food security. Two seasons (i.e. 2020 major and 2020–2021 minor) field experiments were conducted at two lowland within the Mankran watershed in the Ashanti region of Ghana. The experiment comprised thirteen (13) improved varieties and two local checks and was conducted using recommended good agronomic practices. The key findings of the study showed that growth and yield parameters vary significantly between varieties across locations. The biplot analysis showed that varieties FARO 66, SAHEL 317, and Amankwatia are the best in the major season while WITA 9, GT 11, ARS-957-BGJ-171-15-D-B, NERICA L36, and AGRA were the best in the minor season at both locations. Farmers’ preference for the varieties was based not only on growth and yield but on resistance to lodging, pests, and diseases. In conclusion, the best performing varieties have demonstrated yield potential which is about 92% higher than the yield of the local checks and can be recommended for adoption by farmers. Future breeding programs on these varieties should include the most preferred attributes by farmers in this study. GRAPHICAL ABSTRACT

加纳mankran流域提高低地水稻产量的改良水稻品种的产量潜力

加纳的水稻生产受到品种选择少的限制，这使农民在满足消费者的市场需求方面处于不利地位。本研究的目的是(i)评估非洲水稻中心(AfricaRice)开发的改良水稻品种的产量潜力，(ii)允许农民根据在田间观察到的生长和产量选择他们所选择的改良品种，以确保高采用率，提高生产力和粮食安全。在加纳阿散蒂地区Mankran流域的两个低地进行了两个季节(即2020年主要季节和2020 - 2021年次要季节)的现场试验。该试验包括13个改良品种和2个地方检查，并采用推荐的良好农艺规范进行。研究的主要结果表明，不同地区品种间的生长和产量参数差异显著。双图分析结果表明，两个地点的主要品种为FARO 66、SAHEL 317和Amankwatia，而WITA 9、GT 11、ARS-957-BGJ-171-15-D-B、NERICA L36和AGRA。农民对这些品种的偏好不仅基于生长和产量，而且基于抗倒伏、抗虫害和抗病能力。综上所述，表现最好的品种显示出了比当地检查的产量高出约92%的产量潜力，可以推荐给农民采用。未来对这些品种的育种计划应包括本研究中农民最喜欢的特性。图形抽象

期刊介绍： Plant Production Science publishes original research reports on field crops and resource plants, their production and related subjects, covering a wide range of sciences; physiology, biotechnology, morphology, ecology, cropping system, production technology and post harvest management. Studies on plant production with special attention to resource management and the environment are also welcome. Field surveys on cropping or farming system are also accepted. Articles with a background in other research areas such as soil science, meteorology, biometry, product process and plant protection will be accepted as long as they are significantly related to plant production.
