Ecology, 2022 AbstractSeventy five percent of the world's food crops benefit from insect pollination. Hence, there has been increased interest in how global change drivers impact this critical ecosystem service. Because standardized data on crop pollination are rarely available, we are limited in our capacity to understand the variation in pollination benefits to ...

Learning from the Past in the Transition to Open-Pollinated Varieties [PDF]
Sustainability, 2020 In Nepal, hybrid seed introduction caused major yield gains in agricultural production, but at high environmental costs. The development of high-yielding open-pollinated varieties has spurred hope for more sustainable production systems. Nepal’s government is interested in boosting their use.

NONRANDOM MATING IN AN OPEN-POLLINATED MAIZE POPULATION [PDF]
Genetics, 1986 ABSTRACT Randomness of fertilization was studied in an open-pollinated population of maize (Zea mays L.) through allozyme assays of seedlings from open-pollinated seeds produced on both tasseled and detasseled plants. Mixed-mating-model estimates of the amount of outcrossing (t) were not significantly different from t = 1.00 for four ...

Effects of Irrigation Method on Pollination and Pollinators (Hymenoptera: Apoidea) in an Open-Field Tomato Crop [PDF]
Florida Entomologist, 2019 Tomato is one of the highest water-demanding crops, and the use of different irrigation systems and different water management strategies may affect crop yield. Despite the fact that tomato is a self-fertilizing (autogamous) plant, research has shown that bees (“buzz pollination”) improve yield and fruit quality.

Improving Productivity of Open-pollinated Processing Tomato Cultivars [PDF]
HortScience, 2005 In contrast to developed countries open-pollinated (OP) processing tomato cultivars still have a certain market value in Turkey. A total of 26 subpopulations of 6 different OP cultivars (9 of Rio Grande, 5 of Rio Fuego, and 3 of each of C-37, Interpeel, T2 Improved, and VF 6203) were evaluated in two experimental sites in Marmara Region and Aegean ...

Scarcity of ecosystem services: an experimental manipulation of declining pollination rates and its economic consequences for agriculture [PDF]
PeerJ, 2016 Ecosystem services (ES) such as pollination are vital for the continuous supply of food to a growing human population, but the decline in populations of insect pollinators worldwide poses a threat to food and nutritional security.

279 COMPARISON OF OPEN-POLLINATED AND HYBRID CALABAZA [PDF]
HortScience, 1994 Bush and short-vined calabazas [Cucurbita moschata (Duchesne) Poir.] derived from crosses of `Bush Butternut' with `La Primera' and `La Segunda' followed by several generations of selection and self pollination, are quite uniform in plant and fruit characteristics.

Self-fertility studies of some sweet cherry (Prunus avium L.) cultivars and selections
International Journal of Horticultural Science, 2004 Fruit set of two sweet cherry cultivars (Alex' and 'Stella' ) and four Hungarian selections have been studied over two years following open pollination, unassisted self-pollination (autogamy) and artificial self-pollination (geitonogamy).
