The present invention relates to an ALS inhibitor herbicide tolerant polyploid plants, such as B. napus or B. juncea plants, progeny and parts thereof comprising mutations in all acetolactase genes.

A method of applying a Chemical Hybridization Agent (CHA) to a plant. The method includes providing a CHA source and bringing the CHA source in contact with a root of the plant. The method further includes having the root take up a part of the CHA. The disclosure further relates to methods of producing a haploid and/or doubled-haploid plant or hybrid seed. The disclosed method may be used in various aspects of plant breeding.

A composition for regulating plant growth, the active ingredient of which is an ester of oxaloacetic acid or a salt thereof, or derivatives thereof, wherein the ester of oxaloacetic acid has the formula set forth below, where R.sup.1 and R.sup.2 are independently selected from a series of C.sub.1-C.sub.18 alkyl groups, and wherein the content of the active ingredient corresponds to a concentration of from 10.sup.11 M to 10.sup.3 M. The active ingredients and compositions for regulating plant growth allow for treating plants in order to stimulate the growth thereof and achieve such advantages as increased yields, improved plant quality, improved nutrient absorption and enhanced stress resistance, while allowing such advantages to be achieved using a relatively small amount of an active ingredient(s) which is/are biodegradable and environmentally friendly.
