摘要
The quantitative traits ''ear length'' and ''plant height'' were analyzed in maize by means of hybridological and statistical analysis. Matroclinous haploids derived from the parental lines and their direct and backcross hybrids were used. Haploids were obtained by genetic induction. It is proposed that the traits studied are controlled by oligogenes. The results of genetic analysis suggest that haploids of the parental lines are characterized by the interaction of three nonallelic genes in respect to the ear length trait, and by the interaction of two nonallelic genes in respect to the plant height trait. The data obtained shows that haploids have great promise for genetic analysis.
