IMPROVING PRODUCTIVITY OF POJ 2878 SUGARCANE VARIETY THROUGH POLYCROSS WITH BULULAWANG, 6535, AND SIL 04 VARIETIES

Abstract

Indonesia’s sugar production has not been able to fulfill the national demand; thus, increasing productivity is needed. One of the efforts to increase productivity is creating new superior varieties through polycross. This study aims to produce clones from polycross with higher crystal productivity from their female parents. The study took place in IP2TP Karangploso, Malang, from December 2020 to November 2021. We had 24 polycross clones and one female parent (POJ 2878) arranged in a Randomized Block Design with 2 replications. The results showed that the 14 polycross clones (MLG 19/P5/15, MLG 19/P5/16, MLG 19/P5/19, MLG 19/P5/21, MLG 19/P5/24, MLG 19/P5/27, MLG 19/P5/28, MLG 19/P5/30, MLG 19/P5/31, MLG 19/P5/33, MLG 19/P5/37, MLG 19/P5/44, MLG 19/P5/46, and MLG 19/P5/47) had higher crystal productivity (8.38-13.68 t/ha) than the female parent (7.59 t/ha).
