Manual emasculation and pollination of plants to generate plant lines with particular genetic and phenotypic traits, and to generate desired novel combination of . Cowpea flowers are large and showy. In fact, it seemed to lower rates of successful pollinations, which would impede breeding progress. Reproductive biology, phenology, pollen viability and germinability in ... Challenges of breeding 'VIPeas' | Morning Ag Clips PDF Natural Parasitization of Maruca vitrata (Geyer) by Bracon hebetor Shrivelled seeds were also obtained in 2% of the crosses, which on . emasculation and to transfer the pollen grains from male flowers to the stigma of . . Success of crossing with emasculation varied from 5 to 17%; while the success rate varied from 20 to 50% by pollination without emasculation. Ovules were cultured and embryos were later dissected to obtain hybrid plants. The data collected on the number of pods under treatments of different time intervals between emasculation and pollination of chickpea flowers showed that significantly highest number of pods was formed when pollination was carried out 24 hours after the emasculation. The overall success rate was highest (15.33%) in flowers, which were . For obtaining successful emasculation and artificial pollination, prior knowledge of floral biology, that includes time of anthesis and period of stigma receptivity of the species is required. . Early emasculation will hence prevent unwanted self-pollination since it is found that buds greater than this size may have been spontaneously self-pollinated. Two crossing techniques for hybridization of chickpea have been reported and include pollination after emasculation and pollination without emasculation. Floral structure, breeding and pollination mechanism; methods and techniques of seed production in major oil seeds (groundnut, castor, sunflower, safflower, rape and . in pulses (pigeon pea, chick pea, green garm, black garm, field beans, peas etc.). Success . Breeding in Pulses - agriinfo.in UNIT IV Floral structure, breeding and pollination mechanism; methods and techniques of seed production . The chickpea stem is erect, branched, viscous, hairy, terete, herbaceous, green, and solid. Removal of stamens or anthers or killing the pollen of a flower without the female reproductive organ is known as emasculation. Stefaniak and McPhee found this process - called emasculation - does not increase cross-pollination in chickpeas. 4. Cross-pollination is rare; only 0-1 % is reported (Singh, 1987; Smithson et al., 1985). In this method the standard is detached and unfolded. OTHER SPECIES 1.
