The methods of quantitative genetic analysis were presented for estimating the chromosome effects and the gene effects of quantitative characters in common wheat-wheatgrass alien addition Unes. These methods are based on the cytogenetics of addition lines and the priciple of quantitative genetics. The chromosome effects and the gene effects of a Triticum aestivum-Elytrigia elongata (2n = 70) addition line 31505 were estimated. The main results were as follow: a) 6 quantitative characters...

The methods of quantitative genetic analysis were presented for estimating the chromosome effects and the gene effects of quantitative characters in common wheat-wheatgrass alien addition Unes. These methods are based on the cytogenetics of addition lines and the priciple of quantitative genetics. The chromosome effects and the gene effects of a Triticum aestivum-Elytrigia elongata (2n = 70) addition line 31505 were estimated. The main results were as follow: a) 6 quantitative characters in all characters investigated have relation to alien chromosomes. b) Chromosome effects showed dosage effects. Some chromosomes effects affected by the background of common wheat signficantly. c) Additive effects of alien chromosomes ([d']) are the most important gene effects, and they showed similar in different crosses from the same character. d) There are certain interactions between alien chromosomes and common wheat chromosomes.

The recent advances in the genetic research of endosperm-quality traits in cereal crops are outlined. They mainly included (1) the characteristics in their inheritance, (2) the genetic control, (3) the triploid model, (4) the qualitative-quantitative genetic analysis of endosperm traits.The genetic expression of an endosperm trait may be controlled by the genotypes of the endosperm or/and the maternal plant,and additionally possible cytoplasm effect in some cases. The identification of the genetic control is essential to the hereditary investigation of endosperm traits.If an endosperm trait is subject to the endosperm genotype, the triploid model must be employed for the genetic description.If both genetic effects of major gene and polygenes exist,the qualitative-quantitative method should be considered for the genetic analysis.

Non pollinated silk of one set NC Ⅱ mating design (5×5) maize (Zeas mays L.), which were isoplamic allonuclear Es cytoplasmic male sterile lines, was treated by chemicals[treatment A: Ms cultural medium+4% dimethyl sulphoxide (DMSO)+40g/m 3 maleic hydrazide (MH)] and plant hormones [treatment B: N6 cultural medium+100g/m 3 6 benzyl aminopuring(6 BA) + 100g/m 3 gibberellic acid (GA3)] for inducing parthenogenesis seeds were obtained by the above methods. Quantitative genetic analysis was conducted with using frequency of parthenogenesis seed formation as a quantitative character index. Frequency of seed induction was determined as ration of seeds to number of ovaries per ear. The genetic control effects of maternal lines (CMS Es) and paternal lines (normal lines) were analyzed. The results were presented as follow:①Chemically induced parthenogenesis was demonstrated by statistical methods;② Chemically induced parthenogenesis was controlled by maternal lines and paternal lines. It means that maternal cytoplasm and paternal nucleus affected the parthenogenesis induction. The genetic model of parthenogenesis induction was fit for the additive dominance genetic model. Additive gene effects made a greater contribution than the non additive effects to the inheritance of parthenogenesis induction. ③ There was no significant difference between chemical treatment and plant hormones treatment. The induction frequency of parthenogenesis in CMS Es lines was positively corrected with the fertility of CMS Es lines. It indicated that there were difference on genetic background control mechanism which affected induction frequency among chemical treatment and plant hormones treatment as well as fertility of CMS Es lines. The inheritance specific property of chemically induced parthenogenesis, and the value and prospects of parthenogenesis in maize breeding were also discussed in the later paper.
