Scientists in Pakistan are currently evaluating crop seeds that were sent into space to study the effects of cosmic radiation and microgravity on plant genetics. The initiative, a collaboration between the Pakistan Space and Upper Atmosphere Research Commission (SUPARCO) and China, involved exposing wheat, rice, and maize seeds to these unique conditions during a space mission.
Dr. Zahid Mahmood, Program Leader of the Wheat Program at the National Agricultural Research Centre (NARC), explained that this approach is a form of mutation breeding. Unlike traditional methods that use chemicals or ground-based radiation to induce genetic changes, this technique leverages the natural mutagenic environment of space. The goal is to introduce new genetic variations that could lead to desirable traits in crops.
After the seeds returned to Earth, they were initially processed in Karachi before being handed over to researchers. To speed up the research process, the seeds were first grown in NARC’s Speed Breeding Facility, which allows for multiple plant generations per year, bypassing the limitations of traditional field trials that only permit one cycle annually. The resulting plants have now been moved to field trials for comprehensive evaluation.
Researchers are monitoring the plants for a range of beneficial characteristics, including height, disease resistance, grain attributes, and overall yield. They are also employing modern tools like drones with multispectral sensors to quickly and efficiently assess these traits across large trial plots.
Dr. Mahmood emphasized that the work is still in an experimental phase. Not all genetic mutations are helpful, and a lengthy selection process is necessary to identify any lines with improved qualities. The results from these current trials will be crucial for planning future space missions, ensuring that the most suitable crop varieties are selected for exposure.
