high parent
1.The content of Chl. a+b and a/b value in the leaves of the progeny was low, showed dominance to certain degree and existed super-high-parent phenomenon.
7.High-yield restorer, 3-11, as female parent, was crossed to IRBB58, IRBB59 and IRBB60 carrying bacterial blight (BB) resistance genes, respectively at CNRRI, Hangzhou, China. In 2004, three populations at the F_6 generation were obtained through SSD.
8.These mutant strains of baker′s yeast XD198,XD174 and XD193 of high fermentation ability in dough were screened from their parent strain Saccharomyces cerevisiae HZ66 by laser irradiation. The results showed the strain were genetically stable after many times subculture; compared with the parent,the fermentation activity in dough with 15% sucrose of the mutants XD198,XD174 and XD193 were increased significantly 31.3%,35.3% and 32.7% respectively;
