Abstract
TGMS line EC720903, which was imported from IRRI, was evaluate under Kerala condition for its suitability as a female parent in two line rice breeding programmes. The particular line was evaluated for the dates of first and 50 percentage flowering. Pollen sterility as well as spikelet sterility were also noted revealing that this particular line is 100% pollen as well as spikelet sterile all round the year at Vellayani condition. The weather data of Vellayani condition (where the work was carried out) was used to identify the CSP of the line. The same line was also found to be male fertile at RARS, Ambalavayal, which is at a high altitude indicating its locational suitability for seed multiplication.
