  • In the report, 4 photo-thermo-sensitive genetic male sterile （PTGMS） lines, Peiai64S, ZhunS, P88S and Y58S were analyzed by sowing data treatment in Haikou, and the fertility performance was determined by observing the percentage of pollen fertility and seed-setting on the bagged panicles. The results showed that the fertility of Peiai64S was stable from mid-May to late-October, and the temperature sensitive periods （TSP） was 10—25 d before heading; the fertility of ZhunS was stable from May 15th to Oct. 16th, and the TSP was 5—15 d and 19—22 d before heading; the fertility of P88S was stable from May 11th to Oct. 18th; and the TSP was 5—15 d and 18—22 d before heading; the fertility of Y58S was stable from May 5th to Oct. 20th; and the TSP was 7—11d before heading.

Abstract: In the report, 4 photo-thermo-sensitive genetic male sterile （PTGMS） lines, Peiai64S, ZhunS, P88S and Y58S were analyzed by sowing data treatment in Haikou, and the fertility performance was determined by observing the percentage of pollen fertility and seed-setting on the bagged panicles. The results showed that the fertility of Peiai64S was stable from mid-May to late-October, and the temperature sensitive periods （TSP） was 10—25 d before heading; the fertility of ZhunS was stable from May 15th to Oct. 16th, and the TSP was 5—15 d and 19—22 d before heading; the fertility of P88S was stable from May 11th to Oct. 18th; and the TSP was 5—15 d and 18—22 d before heading; the fertility of Y58S was stable from May 5th to Oct. 20th; and the TSP was 7—11d before heading.
