The thermosensitive genic male sterility (TGMS) system has a high potential to develop two-line hybrids, which are more economical for seed production. The ovary culture technique can also help to improve or develop new lines for several economic traits. We therefore cultured unpollinated ovaries from plants of five crosses involving TGMS UPRI 95-140 (P1), the good ideotype UPRI 95-117 (P2), and main- tainers UPRI 95-139 (P3) and UPRI 95-130 (P4). Quality rices-Basmati 385 (P5), Haryana Basmati 1 (P6), and UPRI 95-145 (P7)-were also cultured.
