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.
Claims7
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,
- wherein plant C is a hybrid,
- wherein the seed has at least one improved germination property as compared to the seed obtained by crossing plant A with plant B,
- wherein the improved germination property is selected from the group consisting of germination capacity, uniformity of germination, germination rate, and seedling fresh weight,
- wherein the plant A, the plant B, and the plant C are from Solanum lycopersicum, Solanum pennellii, Solanum habrochaites, Solanum pimpinellifolium, or hybrids thereof, and
- wherein the seed is obtained by pollinating, with pollen of plant B, a periclinal chimera plant comprising an L2-shoot meristem layer that has the genotype of the plant A, and an L1-shoot meristem layer giving rise to the integument of the seed that has the genotype of the plant C.
