Breeding behaviour of shrunken kernels

--Shehalata B. Allagikar, S. E. Pawar and N. K. Notani

In the above unstable cob, occasionally a few shrunken kernels appeared. These upon self-pollination did not give fully shrunken kernels. In fact, most of them phenotypically appeared to be like wildtype. However, in testcrosses to sh1 stock, all the progeny kernels were fully shrunken (Fig. 2). Thus Bombay sh1 allele (sh1-B) is somewhat different from the standard sh1 allele in expression.
