Yield and growth performance of potential sugarcane (Saccharum officinarum L.) hybrid clones

Abstract

Sugarcane development in Indonesia has been done primarily on dry lands. Therefore developing varieties more suitable to dry-agro-ecological conditions is being attempted as it is easily applicable and economically feasible. This study aimed at assessing the yield of 18 potential sugarcane clones, resulting from crosses with parents which have high productivity. This study used Cenning variety as a control. The research was conducted at Karangploso experimental garden Malang, from October 2019 to September 2020. The research used a randomized block design with four replications. The experimental plot was designed with five rows (5 m length) and rows distance at 110 cm. The evaluation was carried out on the growth and production component. The results showed that genotypes affected the performances of growth and yield characters. All of the clones showed good performances in growth. Clones MLG 18/21/14, MLG 18/42/15 and MLG 18/41/5 had productivity 21.08-34.86 (t/ha) and sucrose content 21.79-38.44 (%) higher than control. The three clones select as promising clones for sugarcane development in dry-agro-ecological land with higher productivity yields.
