Adapting Agriculture to Climate Change: A Synopsis of Coordinated National Crop Wild Relative Seed Collecting Programs across Five Continents.

ABSTRACT: The Adapting Agriculture to Climate Change Project set out to improve the diversity, quantity, and accessibility of germplasm collections of crop wild relatives (CWR). Between 2013 and 2018, partners in 25 countries, heirs to the globetrotting legacy of Nikolai Vavilov, undertook seed collecting expeditions targeting CWR of 28 crops of global significance for agriculture. Here, we describe the implementation of the 25 national collecting programs and present the key results. A total of 4587 unique seed samples from at least 355 CWR taxa were collected, conserved ex situ, safety duplicated in national and international genebanks, and made available through the Multilateral System (MLS) of the International Treaty on Plant Genetic Resources for Food and Agriculture (Plant Treaty). Collections of CWR were made for all 28 targeted crops. Potato and eggplant were the most collected genepools, although the greatest number of primary genepool collections were made for rice. Overall, alfalfa, Bambara groundnut, grass pea and wheat were the genepools for which targets were best achieved. Several of the newly collected samples have already been used in pre-breeding programs to adapt crops to future challenges.

Project description:Biochar (BC) application to low-fertility soils enhances crop yield, soil quality, and sustainable agricultural production. Although many studies have explored the effects of biochar on tropical crops, research specific to Bangladesh is limited. Given the agrarian system in Bangladesh, dense population, and vulnerability to climate change, adopting sustainable agricultural practices is essential. This study evaluates the impact of different biochar dosages on the germination and early growth of five major crops Oryza sativa (rice), Triticum aestivum (wheat), Capsicum annuum (chili), Solanum melongena (eggplant), and Solanum lycopersicum (tomato) using Acacia auriculiformis wood-waste biochar. The research was conducted using a randomized complete block design (RCBD) in a nursery setting. Biochar treatments of 10 t/ha and 15 t/ha were applied, with assessments made of germination (%), germination rate (after 7 days), shoot height (cm), root height (cm), leaf number, and root-shoot dry weight ratio. The results indicated a significant (p < 0.001) increase in germination (%) with higher biochar application rates. The linear mixed-effects model showed a significant effect of biochar treatment on germination (%) (F = 57.33, p < 0.001) and a significant interaction with crop type (F = 15.84, p < 0.001). In C. annuum, the 15 t/ha treatment resulted in a 96% increase in germination compared to the control (43.3 ± 1.08% vs 85.1 ± 2.15%). Similarly, in O. sativa, germination was significantly higher with the 10 t/ha (84.5 ± 1.52%) and 15 t/ha (91.8 ± 1.49%) treatments compared to control (59.3 ± 2.38%). Biochar significantly (p < 0.05) influenced early germination rates (after 7 days) and early growth parameters (e.g., shoot length, leaf count, root-shoot ratio), with the 15 t/ha treatment showing substantial improvements for C. annuum and O. sativa, while no significant effects were observed for S. lycopersicum. These findings underscore the potential of A. auriculiformis in enhancing germination and early growth of economically important crops, highlighting its role in promoting sustainable agriculture in Bangladesh.
