Abstract:
The young inflorescences collected from ‘0-30’, the male parent of ‘Shenza 5’,were exposed to
60Co-γrays at a dose of 10GY, then in-vitro cultured on MS media. A total of 89 R
0 regenerants were obtained. Solid and segregating somaclonal variations in seven kinds of visual traits were seen in R
1 generation with a variation frequency of 27.9%. Elite variants were isolated from the R
1 solid and segregating population and crossed to sorghum male sterile lines. A somaclonal restorer called ‘011’ were selected out. The hybrid combination ‘7050A/011’ was featured by its high production and high antifungal.
