Abstract
The present invention provides methods for the production of plant inbred seed, or for the production of plant hybrid seed, wherein the seed obtained exhibits altered and/or improved germination properties, in particular improved germination properties such as enhanced seed germination rate, enhanced seed germination capacity and/or enhanced seedling fresh weight. The present invention also provides for the use of periclinal chimera plants for improving germination properties of seed.
Claims12
A method for the production of a seed with an embryo genotype identical to seed obtained by crossing a first plant A with a second plant B, wherein one or more germination properties of the seed are improved as compared to seed obtained by crossing the first plant A with the second plant B, the method comprising:
- (a) making a periclinal chimera plant comprising an L1- and L2-shoot meristem layer that has the genotype of plant A, and an L3-shoot meristem layer that has the genotype of a third plant C;
- (b) pollinating the periclinal chimera plant with pollen of a plant having an L2-shoot meristem layer that has the genotype of plant B;
- and
- (c) selecting seeds having one or more improved germination properties selected from the group consisting of germination capacity, uniformity of germination, germination rate, and seedling fresh weight,
- wherein the first plant A, the second plant B, and the third plant C are from species belonging to the genus Solanum, and
- wherein the genotypes of plants A and C differ from each other.
