EXPLOITATION of hybrid vigour has now become a potent tool in plant breeding.
The successful utilization of this -phenomenon in enhancing crop production, however,
depends on the economics of hybrid seed production. In crops which are not as fortunately placed as maize with regard to the possibility of producing hybrid seeds
cheaply and on a large scale, extensive research is in progress to isolate spontaneously
occurring male sterile lines. Attempts have also been made to induce the selective
abortion of pollen grains through treatment with various chemicals (see review by
Jain, 1959). Since chemical induction of pollen sterility appears to offer some promise
in several crop plants, experiments were started at the Indian Agricultural Research
Institute in 1955, to standardise suitable techniques for causing male sterility in
wheat, tomato and onion. The results of this study are reported in this paper.
