Abstract
Intergeneric hybrids were produced between hexaploid wheat cultivars P ak-81 and LU-26 and 3 different accessions of Ae. ovata to analyze chr omosome pairing at meiotic metaphase l. Meiotic chromosome pairing in all the hybrids showed significant variation in the frequencies of chi asmata and ranged between 2.10 (Pak-81/Ae. ovata acc: 330487) and 10 ( LU-26/Ae. ovata acc: 361881) per cell. This indicated possibilities of homoeologous chromosome pairing which is helpful in direct transfer o f useful characters from Ae. ovata to wheat cultivars through genetic exchange between the chromosomes of the two species.
