In the triploid x diploid crosses of maize (Zea mays L.) the plump, semiplump, shrivelled
and fluffy kernels had 42.7, 25.5,12.0 and 0'1. survival, respectively. The kernel categories
showed difference in chromosome number variation pattern. The plump kernels contained
23.4% trisomies, whereas the semiplump and shrivelled kernels contained 10.8% and 3.3'1.
trisomies, respectively. Karyotype analysis revealed that any extra chromosome can be
transmitted through the female gamete of the triploid and thus it will be possible to identify
different primary trisomies from the plump kernels of triploid x diploid crosses or its
