Immobilization of tannase from Aspergillus heteromorphus was studied on DEAE-Sephadex A-50, Chitin and Ca-alginate. Among the three methods studied, DEAE-Sephadex A-50 was observed the best support to immobilize A. heteromorphus tannase with 91.5% immobilization. On the other hand Ca-alginate and Chitin supported 79.3% and 34.5% immobilization, respectively. When the immobilized enzyme was studied for its repeated use, a constant decline in the enzyme activity was observed. However, at the end of seventh cycle, operational stability of the immobilized enzyme was 88 %, 61.7 % and 55.7 % for Chitin, Ca-alginate and DEAE-Cellulose, respectively.Keywords

At G.B. Pant University of Agriculture and Technology, Pantnagar (Uttaranchal), 42 top crosses of 14 quality protein maize (QPM) inbred lines (L1, L2, ………L14) with 3 testers (T1, T2, T3) were evaluated using a high-lysine standard check, Shakti-1 in a randomized complete block design during kharif, 2004. Data were recorded on 50% tasselling and silking, plant height, ear height, ear length, ear diameter, kernel rows per ear, 100-kernel weight and grain yield. Significant genotypic differences and wide range of variation in mean values were observed for all the characters studied. Highest heritability in broad sense was observed for grain yield followed by ear diameter, ear length and kernel rows per ear. Maximum amount of genetic advance was found for grain yield followed by plant and ear heights. All characters except days to 50% tasselling and silking showed significant positive correlations with grain yield. Path-coefficient analysis revealed that 100-kernel weight had highest direct effect towards grain yield followed by plant and ear heights.Keywords
