Both fresh and aged seeds of UMI 285, UMI 61 and COH(M) 5, primed with 1% KH2PO4 for 6 hrs produced the longer seedlings in terms of shoot and root length, increased dry matter production and vigour index. Among the genotypes, COH(M) 5 recorded the highest shoot and root length (E and F of Figure-1), increased dry matter production (A of Figure-2) and vigour index than the other genotypes.
