発明の名称 (英語) HEAT-TOLERANT TOMATO MUTANT AND METHOD FOR PRODUCING SAME
発明の概要(英語) Provided is a heat-tolerant tomato plant having a high ability of forming seed-containing fruits under high-temperature conditions. The present invention relates to: a method for producing a heat-tolerant tomato plant, which comprises introducing a genetic mutation for improving the pollen survival rate and the ability of forming seed-containing fruits under high-temperature conditions compared with those of a wild-type plant into a tomato plant; and a heat-tolerant tomato plant having the mutation introduced thereinto.
特許請求の範囲(英語) [claim1]
1.  The comparison seed genetic variants to improve the forming ability of the fruit with the high temperature conditions, the wild-type, comprises introducing into the tomato plant, the method producing the heat tolerance tomato plants.
[2]
[claim2]
2.  Wherein said variant is derived from JHT06 lines represented by accession number FERM BP-22278, method according to claim 1.
[3]
[claim3]
3.  It said mutation, under high temperature conditions, pollen viability, and improves the formation rate and the yield of fruits with seeds A method according to claim 1 or 2.
[4]
[claim4]
4.  Wherein said variant further results in an increase in chlorophyll content of leaves compared to wild type, the method according to any one of claims 1 to 3.
[5]
[claim5]
5.  Wherein said variant is a non-synonymous mutations or genetic defect in at least one gene listed in Table 3, Method according to any one of claims 1 to 4.
[6]
[claim6]
6.  Comprising exposing the tomato plants introducing the mutation at a temperature of 35 ° C ~ 40 ° C, Method according to any one of claims 1 to 5.
[7]
[claim7]
7.  Is produced by the method according to claims 1 to 6 heat tolerance tomato plants the mutations were introduced.
[8]
[claim8]
8.  Accession number FERM a JHT06 line represented by BP-22 278 or its derivative strains harboring the mutations, heat tolerance tomato plant according to claim 7.
[9]
[claim9]
9.  As breeding parent heat tolerance tomato plant according to claim 7 or 8, it crossed with other tomato plants, comprising obtaining a tomato plant having the mutant as progeny plant breeding methods of heat tolerance tomato plants.
