Research Project: Breeding Heat-Tolerant Lettuce and Spinach Varieties for Adaptation to Global Warming
2011 Annual Report


1a.Objectives (from AD-416)
To develop heat-tolerant lettuce and spinach germplasm that is adapted to global warming and low land cost areas of California.


1b.Approach (from AD-416)
We will use germplasm screening and breeding to find and create heat-tolerant lettuce and spinach germplasm, and test them in spring and summer trials conducted in coastal, Central and Imperial Valleys of California.


3.Progress Report

This report documents research conducted under a cooperative agreement with California Department of Food and Agriculture. Global warming and climate change pose serious challenges to California agriculture and place unprecedented pressures on the sustainability of horticulture industry. Adapting the leafy greens industry to future conditions is essential to meet the need of growing population and increasing demand for leafy vegetable products. Initiated experiments to screen lettuce and spinach germplasm for heat-tolerance in growth chambers, and germination of lettuce and spinach varieties at elevated temperatures. This project contributes directly to the Objectives 1 and 3 of the in-house project, genetic improvement of lettuce and spinach.
