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.

A method for the production of 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 L2-shoot meristem layer that has the genotype of plant A, and an L1- and/or L3-shoot meristem layer that has the genotype of a third plant C;
- b) pollinating the periclinal chimera plant with pollen of plant B;
- and,
- c) harvesting the seed thus obtained,
- wherein the genotypes of plants A and C differ from each other.
A periclinal chimera tomato plant comprising an L2-shoot meristem layer derived from a Solanum plant A and an L1- and/or L3-shoot meristem layer derived from a hybrid plant C;
- wherein plant C is a Solanum lycopersicum×Solanum pennellii hybrid plant, a Solanum lycopersicum×Solanum habrochaites hybrid plant or a Solanum lycopersicum×Solanum pimpinellifolium hybrid plant;
- and wherein the genotypes of plants A and C differ from each other.
A seed comprising an embryo with a genotype identical to a genotype obtained by a cross of plant A and plant B and an integument having the genotype of plant C, wherein the genotypes of plants A and C differ from each other, and wherein the seed has at least one improved germination property as compared to the seed obtained or obtainable by crossing plant A with plant B.
