Selection of forage grasses for cultivation under water-limited conditions

“

The perspectives of the above study are very promising. The results indicate that the use of Manhattan distance in conjunction with TOPSIS is effective in the genotypic selection of more stable tropical forage grass varieties under water stress conditions. These findings have significant implications for the sustainability of beef production, especially in the face of extreme weather events such as severe droughts. By identifying varieties that are more resistant to water stress, the study suggests possible advances in creating new genotypes adapted to water scarcity. The varieties 'ADR 300', 'Pojuca', 'Marandu' and 'Xarae´s' are highlighted as particularly stable under water stress conditions, making them promising candidates for genetic improvement programs. These advances have the potential to improve the resilience of tropical forage plants, contributing to food security in regions prone to extreme weather events. Furthermore, the study's findings provide a solid basis for guiding agricultural practices and crop selection strategies in environments affected by water stress. Future perspectives may include applying these findings to practical genetic improvement programs and the development of more resilient pasture management strategies, benefiting beef production in the face of climate change and environmental variability.
