Description Inheritance of geneic male sterility in GMS line MS-1 of okra [Abelmoschus esculentus (L.) Moench.] was
studied using F1
, F2
and test-cross generations of crosses between GMS line MS-1 and normal fertile genotypes, and
the varieties Arka Anamika, Parbhani Kranti, Arka Abhay, IIHR-108-1-31, IIHR-109-20-6, IIHR-116-23-6, IIHR 180-6-3, IIHR-161-10-1 and IIHR-130-2-10. All the F1
were found fertile. Segregation of pollen fertility in F2
and test
- cross generations involving ms1 was segregated in the ratio 1 fertile: 1 sterile, respectively. This indicated that
GMS trait in the line is controlled by a single recessive gene (ms1ms1). Large-scale F1
hybrid seed production in
okra becomes rather slow due to the tedious hand-emasculation, followed by hand-pollination, incurring additional
labour and cost of F1
seed production. In comparison to fertile lines, this saves approximately 70% time and manual
labour. Use of Geneic Male Sterile (GMS) line MS-1 can make F1
hybrid seed production in okra easy and more
economical compared to hand-emasculation.
