Abstract: The present invention relates to a teosinte crossing barrier trait. Plants containing said trait exhibit the phenotype of cross-incompatiblity. The present invention also relates to new cross-incompatible plants, including inbred, hybrid, haploid, apomictic and/or genetically engineered plants, containing the teosinte crossing barrier trait and exhibiting commercially desirable characteristics.

Abstract: The invention relates to a method for producing Brassica oleracea with elevated anticarcinogenic glucosinolate derivatives. The elevated levels are obtained by crossing wild Brassica oleracea species with Brassica oleracea breeding lines, and subsequently selecting hybrids with levels of 4 -methylsulfinylbutyl and/or 3-methylsulfinylpropyl glucosinolates elevated above that initially found in Brassica oleracea breeding lines. The invention also relates to edible Brassica plants, such as broccoli plants, with elevated levels of 4-methylaulfinylbutyl glucosinolate and/or 3 -methylsulfinylpropyl glucosinolates, and to seeds of such plants.

Abstract: The invention relates to improved methods of hybrid seed production. More particularly it relates to the use of one (or two) phytotoxic chemical resistant genes in the male (and female) parent in a hybridization process, followed by uncontrolled pollination and dosing the resultant hybrids with the one (or two) phytotoxic chemicals to eliminate plants arising from unwanted contaminating seeds and thus producing pure F.sub.1 hybrids.

Abstract: Inbred broccoli line, designated BC-403 is disclosed. The invention relates to the seeds of inbred broccoli line BC-403, to the plants of inbred broccoli line BC-403, and to methods for producing a broccoli plant produced by crossing the inbred line BC-403 with itself or another broccoli line. The invention further relates to hybrid broccoli seeds and plants produced by crossing the inbred line BC-403 with another broccoli line.
