Popis:	This paper deals with the application of a laboratory test for shatter resistance in rapeseed to genetic and breeding studies of this character. This test is based on measuring the strength of the siliquae. Siliqua strength is positively correlated with shatter resistance. All the Brassica napus lines studied were shatter susceptible while some lines of B. juncea had intermediate shatter resistance. Certain lines of B. campestris vars Yellow Sarson and Brown Sarson were highly shatter resistant. In the Sarsons shatter resistance was recessive and controlled by two to three loci which showed dominant epistasis. There was considerable variation for siliqua strength in segregating populations of crosses between the Sarsons and B. napus and in progenies derived from irradiation of the B. napus cv. Midas. These materials provide good potential for incorporating shatter resistance in rapeseed.
