Abstract

Four promising hybrids along with female parent and Viswam variety were evaluated for growth and yield under open, twenty five percent and fifty percent shade levels. Among the hybrids, PI 9, PI 63 and PI 140 recorded higher plant height, number of laterals, number of spikes, fresh and dry spike yield per plant which were on par but significantly higher than the present popular variety “Viswam” released by the Kerala Agricultural University. The hybrid PI 63 was found to be the most promising hybrid followed by PI 9 under open condition. At 25 per cent shade, hybrid PI 140 produced higher fresh and dry spike yield per plant. However, at 50 per cent shade, Pl 9 produced maximum spike yield. Yield was higher at lower shade level (zero per cent) compared to higher (25 per cent and 50 per cent).
