ABSTRACT
Fourteen sugarcane genotypes and two check cultivars were evaluated in randomizedcomplete block design with three replications at Sugar Crops Research Institute Mardan during 2012-13 and 2013-14. The studies were conducted in two plant crops to calculate broad sense heritability (repeatability), genetic gain and correlations among the parameters, and establish selection criteria.Highly significant (p ≤ 0.01) differences were found among the genotypes for number of tillers, plant height, cane length,number of nodes, internodes length,number of millablecane and cane yield while non-significant differences were recorded for cane diameter. The effect of genotype and crop interaction was highly significant fornumber of tillers while non-significant for other characters. Broad sense heritability for different characters showed varying levels and it was higher for internodes length (43%), number of nodes (39%),cane length (39%), plant height (30%), number of tillers (12%), cane yield (41%) andnumber of millablecane (35%),respectively indicating that these traits could be selected in the improvement of crop yield. Genetic gain was higher for cane length (36.53 cm), plant height (31.84 cm) and number of tillers (12.98 tillers per 9 m2). Number of tillers (rg=0.96, rp =0.83), plant height (rg =0.95, rp = 0.81), cane length (rg =0.90, rp = 0.76), number of nodes (rg =0.79, rp = 0.67), internodes length (rg =0.80, rp =0.74) and number of millablecane (rg =0.96, rp = 0.87) exhibited highly significant and positive correlation with cane yield at genotypic and phenotypic levels.
