Evaluation of coriander (Coriandrum sativum L.) genotypes for fresh, dry biomass yield and oil content under different seasons

The present study was carried out at Department of Spices and Plantation Crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore during three seasons viz., season I (June 2008-August 2008), season II (October 2008-December 2008) and season III (June 2009-August 2009). From the study on mean performance of genotypes, based on various growth, yield and quality attributing traits of genotypes viz., CS 101 (20.50, 23.25 and 13.35 g, respectively), UD 685 (15.18, 19.51 and 10.45 g, respectively) and CS 136 (13.53, 10.89 and 9.46 g, respectively) were identified as high yielding leafy types during three seasons. Whereas CS 101 (4.10, 4.65 and 2.67 g, respectively) and CS 685 (3.04, 3.90 and 2.09 g, respectively) recorded the maximum dry herbage yield during all three seasons. During the first, second and third season, CS 101 recorded the maximum content of oil (0.54, 0.54 and 0.54%, respectively), followed by UD 685 (0.47, 0.48 and 0.47%, respectively) and CS 136 (0.44, 0.43 and 0.43%, respectively). These genotypes can be used successfully for further breeding programmes.
