Abstract

                                The performance of parents and their hybrids in onion assessed at IIHR, Bangalore during July-2011 to May-2012. The parents used PBRC-337 (T3),PBRC-339 (T5) and PBRMS-319 (L3) were found high yielding with 21.50, 20.33 and 20.67 total bulb yield tonnes per hectare respectively. The hybrids PBRMS-319 x PBRC-339 (L3 x T5 ) and PBRMS-318 x PBRC-338 (L2 x T4) recorded high yield of 27.40 and 26.33 total bulb yield tonnes per hectare respectively along with low PDI for purple blotch disease in onion. The hybrid PBRMS-319 x PBRC-339 (L3 x T5) was most promising for various traits which contribute to higher yield. Based on their performance these parents can be used for further breeding programme and promising hybrids could be explored for cultivation.

Key words : onion, hybrids, purple blotch disease, yield.
