ADAPTATION OF DIFFERENT SUGARCANE CLONES OF PHILIPPINE IN SEMI-ARID CONDITIONS OF PUNJAB, PAKISTAN

Abstract

Present study was conducted at Surgarcane Research Institute, Faisalabad, Pakistan during 2018-19 to evaluate twelve (12) exotic sugarcane clones imported from Philippines for biometric traits and diseases resistance in local climatic conditions. These clones were put in preliminary yield trials (4th stage) of varietal development program to evaluate their performance in comparison with local check varieties HSF 240 and CPF 249. The exotic genotypes along with local checks were subjected to randomized complete block design (RCBD) by keeping three replications during crop season 2018-19. Six biometric traits like germination%, tillers per plant, no. of canes, cane weight, cane yield and sugar contents along with resistance to two major diseases viz. red rot and smut of sugarcane were studied. Two-sided Dunnett’s multiple test was used for comprehensive comparison among bimetric traits. The results of this study indicated that all the clones differed significantly for their agronomic traits. Although some varieties of Philippines showed better performance for cane yield (PSR 01-46, 184.7 t/ha) as compared to check varieties but they could not surpass them for sugar contents (11.54%) and also found susceptible to red rot and smut diseases. Only three exotic clones viz. PSR 01-28, PSR 98-11 and PSR 99-182 were promoted to next selection stage of varietal development program on the basis of higher or comparable cane yield (120.7, 141.7 and 105.3 t/ha, respectively) than check varieties and diseases reaction. However, the sugar contents of these exotic clones were found at par with check varieties and thus further testing and evaluation is required to improve adaptability and stability for consistent performance under local agro-ecological conditions.
