Wild species have been exploited most often as sources of biotic and abiotic stress resistance. Several varieties of wheat, oat, rice, potato, tomato, sunflower, okra, crucifers, tobacco, snapbean, and maize carry the genes for resistance introgressed from the distant species and related genera at some stage and thus surviving in the field.

Climate Change and Wild Species
2013Climate has varied on geological timescales, and ecological systems have responded. Atmospheric CO2 has increased 36% and methane ~160% since the beginning of the Industrial Revolution (~1750), resulting in the globe warming ~0.85°C. Species are responding by rearranging their ranges.

Conservation of wild Lilium species
Biological Conservation, 1974Abstract This review considers the question of whether nature reserves are of practical value to horticulture, using the case of lily culture. In both agriculture and horticulture there is a constant readjustment with Nature to conquer diseases, create new plant forms, or adapt the existing cultivated forms to special conditions of soil, climate, and

American Potato Journal, 1989
Methods for incorporation of wild species germplasm intoSolanum tuberosum must be developed to efficiently utilize their desirable traits. This study was conducted to determine whether wild species selected for tuberization under long-day conditions produce haploid-species hybrids that tuberize better than hybrids with unselected species parents ...

Evaluation of tuber traits of 10,2x(2EBN) wild species through haploid × wild species hybrids
American Potato Journal, 1989The wild species of potato do not tuberize under long day conditions making evaluation of their tuber characteristics difficult. HaploidTuberosum × wild species hybrids provide a means of evaluating the tuber characteristics of the 2x, wild species. Seventy-eight haploid × wild species hybrid families were evaluated for yield, specific gravity, percent

Calystegines in wild and cultivated Erythroxylum species
Phytochemistry, 2005Calystegines were identified in the genus Erythroxylum for the first time. Erythroxylum novogranatense var. novogranatense, a species cultivated for cocaine production, contained 0.2% total calystegines in dry leaves. Forty six Erythroxylum herbarium species consisting mostly of leaf tissue were analysed for calystegines, and 38 were found positive ...

2n pollen in eleven 2x, 2EBN wild species and their haploid x wild species hybrids
Potato Research, 1988Sixty-three plants producing 2n pollen were identified among 65 introductions of 11 2x, 2EBN wild species. They were found in 27 of the 65 introductions representing ten of 11 species. The gene frequencies for the allele controlling 2n pollen formation ranged from 0.19 to 0.65. Seventyeight haploid x wild species hybrid families were produced using the

Antimicrobial Potential of Wild Edible Herbaceous Species
2016Natural products, either as pure compounds or as standardized extracts, provide unlimited opportunities to control microbial growth, owing to their chemical composition and diversity. Many herb and spice extracts possess antimicrobial activity against a range of bacteria, yeast, and moulds.
