Exploring the Natural Variation for Seedling Traits and Their Link with Seed Dimensions in Tomato

摘要: The success of germination, growth and final yield every crop depends to a large extent on the quality seeds used grow crop. Seed is defined as viability vigor attribute seed that enables emergence establishment normal seedlings under wide range environments. We attempt dissect mechanisms involved in acquisition quality, through combined approach physiology genetics. To achieve this goal we explored genetic variation found RIL population Solanum lycopersicum (cv. Moneymaker) x pimpinellifolium extensive phenotyping seedling traits both nutrient stress conditions root system architecture (RSA) optimal conditions. have identified 62 major QTLs 21 different positions for seed, RSA population. were common across conditions, well specific Most co-located with size weight positive alleles mostly contributed by S. parent. Co-location might suggest same locus has pleiotropic effects multiple due mechanistic basis. show strong effect these results are great importance isolation corresponding genes elucidation underlying mechanisms.
