A diploid Solanum clone 9507-04 was used to grow anther-derived plantlets that were putatively monoploid. Sixteen RAPD primers were used to observe the RAPD profiles from anther-donor and anther-derived materials. A total of 56 RAPD markers were scored and each marker was identified according to the primer’s designation and size (kilo base pairs) of the amplified fragment. Of 56 RAPD markers as...

Calotropin isolated and characterized from the roots of Calotropis procera when administered to gerbils (25mg/kg b.wt) and rabbits (25mg; kg b.wt) each day for a period of 30 days inhibited the process of spermatogenesis. The population of spermatids was depleted by 65% and 94% in gerbils and rabbits. The seminiferous tubules and the Leydig cell nuclei diameters were reduced in both the species...

This study evaluated intra-testicular injection of sodium chloride for chemical-castration in 12 mix bred dogs (6 adult and 6 non-adult). The sodium chloride at 20% concentration per testis were injected intratesticularly until tension occurs and the testicles were removed with the open surgical technique about 30 days for histopathologic evaluation. Testicular swelling was evident in both grou...

haploid plant per floret (Devaux, 1988). Androgenesis induction in microspores may be affected by various An efficient doubled-haploid production technology that induces factors which cause low induction efficiency and by gehomozygosity can greatly reduce the time and cost of cultivar developnotype dependence (Dunwell, 1985). Most advances toment. Low efficiency of doubled-haploid production pr...
