Provided here are methods of using a mutated patatin-like phospholipase IIα ('pPLAIIα,' renamed here MATRILINEAL) to induce haploid induction in plants, cloning a pPLAIIα to induce haploid induction in plants, and genetically engineering a plant to contain a mutated pPLAIIα. Also provided are methods of applying topical and spray chemicals, lipids, and RNAi molecules to plants during pollination in order to induce haploid production. Further provided are methods of chemically treating plants during pollination to induce haploids while also reducing embryo abortion and increasing seed set.

Haploid induction compositions and methods for use therefor

The present invention provides an inbred corn line designated BDAX4608, methods for producing a corn plant by crossing plants of the inbred line BDAX4608 with plants of another corn plant. The invention further encompasses all parts of inbred corn line BDAX4608, including culturable cells. Additionally provided herein are methods for introducing transgenes into inbred corn line BDAX4608, and plants produced according to these methods.
