Abstract: | Summary Two monosomics of Phaseolus vulgaris (2n = 22) were found among selfed progeny of plants treated with colchicine. The monosomic chromosomes involved were identified as chromosomes H and J according to the previously suggested Giemsa karyotype. Both monosomic plants had slower growth rate and smaller size as compared with their respective euploid sibs. However, no apparent morphological characteristics distinguished the two monosomics. The frequencies of transmission through selfing of monosomics H and J were 9% and 10 % respectively. |
