    Red triveni, a promising rice variety
    (Kerala Agricultural University, 1993) Rosamma, C A; Karunakaran, K; Rajappan Nair, N
    Reselection has been effectively utilised as a breeding programme for defect elimination by many workers and a successful programme in this direction is discussed in this paper. Reselection was attempted in the variety Triveni in order to overcome the drawback of sprouting of grains on the panicle itself under high moisture conditions. While attempting for reselection, red riced plants which might have evolved through natural mutation were identified. Red riced plants wilh dormancy were selected after progeny testing and the new line was designated as Red Triveni. Red Triveni exhibited dormancy fora period of 15 to 20 days. Performance of this culture was highly promising in all the station trials and adaptive trials and was released as Ptb 45.

    Breeding for photosensitive high yielding rice variety
    (Kerala Agricultural University, 1994) Rosamma, C A; Elsy, C R
    An ideal rice variety with high gram and straw yield, adaptability to the rabi season and consumer preference was evolved at the Regional Agricultural Research Station, i'attambi from the cross between Co 25, Triveni and Vellathil Kolappala. This variety called Niln (Ptb 48) combines in itself high grain and straw yield under average management conditions, adaptability to the season and tolerance to most of the pests and diseases.
