An experiment was carried out to study the crossability and genetic relationship in F1s of two wild and three cultivated rice genotypes viz., Wild 4855, Jhora 4325, Dular, Hab. Aman 2 and Jagliboro. Seed set percentage in diallel progenies (without reciprocal) of five rice genotypes ranged from 4.91 to 65.77%. Crossability of Jhora 4325 was highest with Jagliboro followed by Hab. Aman 2, Dular and Wild 4855 that indicate the closeness of the genotypes with each other. Among the cultivated genotypes crossability of Dular with Jagliboro was highest followed by Hab. Aman 2, Jhora 4325, respectively. On the other hand Hab. Aman 2 showed highest crossability with Jagliboro followed by Jhora 4325. Jagliboro showed higher crossability in all the crosses, which could be count as a key genotype in the evolutionary process of the five rice genotypes.
