We need varieties that are tolerant or resistant to drought and extreme tempera- tures. And we need forages that will do more to stabi- lize and restore lands where production is now limited by excessive erosion, low fertility, and salinity. To develop varieties that are tolerant or resistant to environmental hazards, more information is needed onâ ⢠Improving techniques for measuring drought resistance. ⢠Finding better procedures for evaluating toler- ances to low and high temperatures. ⢠Determining resistance of species and varieties to saline conditions. ⢠Measuring grazing tolerance and proper season of use as related to persistence. ⢠Identifying morphological and anatomical char- acteristics associated with resistance and suscepti- bility. ⢠Establishing the association between seeding and mature plant behavior. ⢠Isolating species that have promise for use on ilifficult sites. ⢠Selecting varieties with improved adaptation to environmental ?:â â Information on the adapted characteristics of species, varieties, and experimental selections is obtained from field experiments.
