Introduction to crop wild relatives por Volk, Gayle M., Khoury, Colin K., Greene, Stephanie L., Byrne, Patrick

“…Although CWR are likely to be the key to future crop improvements, as wild species, they may be lost if there are shifts in their native habitats. Ex situ genebank collections (maintained under cultivated conditions) provide an opportunity to conserve and protect crop wild relatives for future generations.…”

Gender Roles and Native Potato Diversity Management in Highland Communities of Peru por Molina, C.A., Dudenhoefer, D., Polar, Vivian, Scurrah, M., Ccanto, R.C., Heider, B.

“…This article reviews agricultural and crop diversity management practices, farmer motivations for conserving potato diversity, the role that agrobiodiversity plays in family diets and economies, and support of in situ conservation by external actors. It examines how gender norms limit the potential of women to fully benefit from the crop and argues for more gender-responsive approaches that empower both women and men, enable women to overcome barriers, and contribute to a more inclusive, community-based management of agrobiodiversity that ensures its long-term conservation and contribution to community development and well-being.…”

A new two-decade (2001–2019) high-resolution agricultural primary productivity dataset for India por Gangopadhyay, Prasun K., Shirsath, Paresh B., Dadhwal, Vinay K., Aggarwal, Pramod K.

“…Along with validation with crop statistics, the derived dataset was also compared with in situ GPP estimations. This dataset will be useful for many applications and has been created for estimating integrated yield loss by taking GPP as a proxy compared to resource and time-consuming field-based methods for crop insurance.…”

Recovery from cucumber mosaic virus infection for ‘Calwonder’ bell pepper plants does not counter negative impacts on plant growth por Murphy, John F., Masiri, Jongkit, Hadi, Buyung A. R., Dute, Roland R.

“…Four symptom phases occurred in successive order, designated chlorosis (leaves 6–8), mosaic (leaves 9–11/12), leaf distortion (first series of leaves on secondary and tertiary branches) and recovery (progressive recovery with newly emerging leaves in tertiary and younger branches). In situ detection of CMV in leaf tissues revealed widespread occurrence in leaves expressing chlorosis and mosaic symptoms but reduced, localized occurrence in leaves in the recovery phase. …”
