An isolated solely pollen-specific promoter derived from Arabidopsis comprise a nucleotide sequence of Arabidopsis PLA2-δ gene. The novel promoter has specific roles in particular organs and at particular developmental stages, such as in mature flowers, and can be used in the production of hybrid seeds using male sterility techniques.

A novel hybrid maize variety designated X4M830 and seed, plants and plant parts thereof, produced by crossing Pioneer Hi-Bred International, Inc. proprietary inbred maize lines. Methods for producing a maize plant that comprises crossing hybrid maize variety X4M830 with another maize plant. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into X4M830 through backcross conversion and / or transformation, and to the maize seed, plant and plant part produced thereby. This invention relates to the hybrid seed X4M830, the hybrid plant produced from the seed, and variants, mutants, and trivial modifications of hybrid X4M830. This invention further relates to methods for producing maize lines derived from hybrid maize variety X4M830 and to the maize lines derived by the use of those methods.

The invention discloses a honey bee attractant and a method for seed production and pollination of a soybean hybrid seed in a field. The honey bee attractant is prepared from cellular liquid, imitation flower liquid, syrup and water. The method comprises the steps of: selecting the field suitable for growth of soybean, sowing the soybean hybrid seed in good time, interplanting a male parent and a female parent at an interval of a ridge, selecting required quantity of healthy pollination swarm before pollination, transporting the healthy pollination swarm in the soybean field at an early flowering stage of the soybean; feeding attractant syrup one hour before spraying the honey bee attractant in each day or at an interval of a day; forming 1-5 ridges for every1-3 days, spraying the honey bee attractant on hybrid soybean plant leaf of the male parent and the female parent in the 1-5 ridges; inducing a large quantity of bees to gradually fall on the hybrid soybean plant leaf to eat the attractant syrup; then spraying the honey bee attractant on the two sides of a hybrid soybean strain stem, inducing the bees to climb on the soybean strain stem and continue to climb on the soybean to collect, thereby pollinating the hybrid soybean; stopping spraying the honey bee attractant in a cloudy or rainy day, and spraying the honey bee attractant when the weather gets nicer, so as to keep enough attractant required for inducing the bees in the field.
