Adoption of improved varieties is an important strategy to adapt to the negative implication associated with climate change and variability. However, incomplete data on varietal release and adoption is often the reality in many countries hindering informed decision-making on breeding and varietal dissemination strategies to effectively adapt to climate change. In taking the example of potatoes in India, we analyze the extent to which the potato sector is resilient to climate change. We do so by comparing state-level climate change projections with adoption of high resistant and tolerant potato varieties to major abiotic and biotic stresses. Release and adoption data was collected in 2016 in six expert elicitation workshops conducted with 130 experts from the potato value chain in Bihar, Gujarat, Karnataka, Punjab, Uttar Pradesh, and West Bengal. We found that from the total of 81 releases, 45 improved varieties are adopted in India and that in each state high resistant and tolerant varieties are cultivated providing some degree of varietal resilience. Early maturity has been the most important and heat tolerance is the least important trait. Comparing climate projections with adoption rates of high resistant and tolerant varieties, we found that Gujarat is relatively most resilient. In other states we found some mismatches between climate projections and adopted specific varietal traits. Our results allow policy-makers and breeders to better prioritize investments into breeding for specific traits and dissemination strategies.

马铃薯品种的采用及其在印度适应气候变化中的作用

采用改良品种是适应与气候变化和多变性相关的负面影响的重要策略。但是,在许多国家,关于品种释放和采用的数据不完整经常会成为现实,阻碍了有关育种和品种传播战略的有效决策,以有效适应气候变化。以印度的马铃薯为例,我们分析了马铃薯部门对气候变化的抵御能力。为此,我们将州一级的气候变化预测与对主要非生物和生物胁迫的高抗性和耐性马铃薯品种的采用进行了比较。2016年,在比哈尔邦,古吉拉特邦,卡纳塔克邦,旁遮普邦,北方邦和西孟加拉邦的马铃薯价值链的130名专家举办的六个专家启发研讨会上收集了释放和采用数据。我们发现,在总共81个版本中,印度采用了45个改良品种,每个州都种植了高抗性和耐性品种,提供了一定程度的品种抗逆性。早熟是最重要的,耐热性是最不重要的特征。将气候预测与高抗性和耐性品种的采用率进行比较,我们发现古吉拉特邦的抗逆能力最强。在其他州,我们发现气候预测与采用的特定品种性状之间存在一些不匹配。我们的结果使政策制定者和育种者可以更好地将投资优先用于特定性状和传播策略的育种。印度采用了45个改良品种,每个州都种植了高抗性和耐性品种,提供了一定程度的品种抗逆性。早熟是最重要的,耐热性是最不重要的特征。将气候预测与高抗性和耐性品种的采用率进行比较,我们发现古吉拉特邦的抗逆能力最强。在其他州,我们发现气候预测与采用的特定品种性状之间存在一些不匹配。我们的结果使政策制定者和育种者可以更好地将投资优先用于特定性状和传播策略的育种。印度采用了45个改良品种,每个州都种植了高抗性和耐性品种,提供了一定程度的品种抗逆性。早熟是最重要的,耐热性是最不重要的特征。将气候预测与高抗性和耐性品种的采用率进行比较,我们发现古吉拉特邦的抗逆能力最强。在其他州,我们发现气候预测与采用的特定品种性状之间存在一些不匹配。我们的结果使政策制定者和育种者可以更好地将投资优先用于特定性状和传播策略的育种。将气候预测与高抗性和耐性品种的采用率进行比较,我们发现古吉拉特邦的抗逆能力最强。在其他州,我们发现气候预测与采用的特定品种性状之间存在一些不匹配。我们的结果使政策制定者和育种者可以更好地将投资优先用于特定性状和传播策略的育种。将气候预测与高抗性和耐性品种的采用率进行比较,我们发现古吉拉特邦的抗逆能力最强。在其他州,我们发现气候预测与采用的特定品种性状之间存在一些不匹配。我们的结果使政策制定者和育种者可以更好地将投资优先用于特定性状和传播策略的育种。
