An efficient in vitro system for early generation selection of heat-tolerant potato breeding materials was tested and validated in field conditions. At the family level, family groups expected to be heat tolerant due to their genetic background were identified as heat tolerant. In the in vitro assay, LTVR × LTVR, an advanced heat-tolerant breeding population developed at CIP, had 100 % of plants with tubers at 18 °C, 73 % at 25 °C and 2 % at 32 °C in the dark. The results from true seed family… CONTINUE READING
