Crop wild relatives (CWR) are valuable sources of variation for the genetic improvement of crops. Mexico is an important center of diversity of crops and CWR. However, this diversity is threatened by climate change, habitat degradation, increasing human population, among other factors. Given the large number of CWR, the creation of a CWR inventory is the starting point for the development of a national CWR conservation strategy. The process for the preparation of a national CWR inventory for Mexico consisted of (i) producing a list of national crop species, (ii) matching the crop genera with the list of national flora to produce a CWR checklist, and (iii) prioritizing the CWR checklist according to a series of selection criteria and using a ranking system. The selection criteria included the economic value of the related crop, the potential for crop improvement, food intake, threat status, geographical distribution, and crop use. Applying these criteria, 310 prioritized CWR taxa were selected (~2% of the national CWR diversity), integrating the national CWR inventory. They are mostly related to food crops of national but also global importance, such as maize (Zea mays L.), common bean (Phaseolus vulgaris L.), chili pepper (Capsicum annuum L.), squash (Cucurbita spp.), potato (Solanum tuberosum L.), cassava (Manihot esculenta Crantz), and sweet potato [Ipomoea batatas (L.) Lam.]. Approximately 31% of the taxa are endemic to Mexico. The inventory will help to develop in situ and ex situ conservation plans as part of a national CWR conservation strategy.

Multitrait differential response in a diverse potato panel under contrasting water regimes

et al. 2020

View full text Add to dashboard Cite

Water stress is the most significant environmental stress in agriculture worldwide.Potato (Solanum tuberosum L.) is a drought-susceptible crop. Water stress tolerance is a complex trait of increasing importance in potato. The objective of this work was to evaluate the differential response strategies associated with water stress tolerance in a highly diverse potato panel. Multienvironment trials were assessed, both in field and in glasshouse with contrasting water regimes. The yield, dry matter, and frying ability were measured in the field assays, whereas proline concentration (PrC), relative water content (RWC), and water consumption (WC) were measured in the glasshouse assays. A mixed linear model and ANOVA were performed. The best linear unbiased predictors (BLUPs) of every genotype for each measured variable were estimated.Pearson correlation coefficient (r) and principal component analysis (PCA) assessed the association among traits. The genotypes were ranked by their BLUPs values. The high diversity potato panel showed variability both in the response to water stress and within each water regime. In general, Solanum tuberosum spp. andigena genotypes were associated with the lowest PrC and higher yield, WC, and RWC. By using BLUPs, a panel of genotypes with good performance under water deficit was defined. This paper provides knowledge useful to design breeding strategies to water stress tolerance and new physiological research lines. The utilization of the elite genotypes identified in this study as progenitors constitute a starting point for breeding programs oriented to develop water-stress-tolerant varieties.
