EVALUATION OF DIFFERENT MULBERRY VARIETIES FOR PHYSIOLOGICAL TRAITS

Evaluation of different mulberry varieties for various physiological traits was conducted using five improved varieties (Morus spp.) namely S-13, S-34, S-36, S-l. V-1 along with K-2 as control. The experiment was carried out under fully irrigated condition under RBD with 4 replications. Plantation spacing was 60 x 60 cm with fertilizer dosage of FYM (a 20MT/ha/yr and N. P. K. (a) 300: 120:120 Kg /ha/yr as per recommended packages of practice for mulberry crop. Evaluation of important physiological traits in comparision to Kanva-2 (check variety) varieties for important physiological traits in comparison to Kanva-2 (check variety showed genotypic variation with significant differences. The transpiration rate was low in S-13 followed by S-34. S-34 and S-1 showing lesser transpiration rate, higher moisture content. higher moisture retention capacity and higher photosynthetic rate. The investigation carried out on the effect of different seasons of a year on mulberry varieties for physiological traits was non-significant indicating that varietal performance were not much affected but maintained the same genotypic differences.
