Seed-set evaluation of four male-sterile, female-fertile soybean lines using alfalfa leafcutting bees and honey bees as pollinators

Abstract: Male-sterile, female-fertile plants were used to produce hybrid soybean seed. Manual cross-pollination using male-sterile plants to produce large quantities of hybrid seed is difficult and time-consuming because of the low success rate in cross-pollination. Insect pollinators may be suitable vectors to transfer pollen, but the most suitable vector for pollen transfer from the male parent to the female parent has not been identified for soybean. The objective of the present study was to evaluate seed-set on fou… Show more

“…With the development of male sterile and insect pollination systems for soybean, it will become possible to conduct one to three cycles of RGS per year (Ortiz-Perez 2008; Davis, personal communication). This will enable increased selection intensities and greater immediate genetic gains from GS because much larger numbers of progeny can be evaluated without the commensurate added expense of increased numbers of field plots (Heslot et al 2015).…”

“…In the last 10 years, many researchers have tried to find external factors that can improve the frequency of natural cross-pollination. For example, insects such as alfalfa leaf-cutting bees and honey bees cannot only improve the soybean yield but also significantly enhance the outcrossing pod-set rate of CMS lines (Ortiz-Perez et al, 2008; Yang et al, 2008; Zhao et al, 2009; Wang et al, 2010; Milfont et al, 2013; Blettler et al, 2017; Dai et al, 2017), and a relatively low temperature before the flowering stage can also enhance the soybean outcrossing rate (Shimamura et al, 2010).…”

“…Also the planting with a single flower colour had a significantly higher out-crossing rate than the plantings with mixed flower colours. Ortiz-Perez et al (2008a) compared honeybees and alfalfa leaf cutting bees at two locations for 3 years using male-sterile, female-fertile soybean genotypes. Neither the effect of pollinator species nor the interaction effect of pollinator species 9 location was significant for any year for seed-set.…”
