Abstract:

The three-line method (A/B/R) of heterosis breeding is cumbersome and warrants development of alternate approaches to exploit hybrid vigor commercially in rice. Two-line breeding is one such possibility that emerged following the chance discovery of photoperiod-sensitive genic male sterile (PGMS) lines and thermosensitive genic male sterile (TGMS) lines in China.
