Influence of High-Sugar Early and Mid-Late Genotypes on Yield and Quality of Sugarcane (Saccharum spp. Hybrid Complex) at Wider Row Spacing

Abstract

A field experiment was conducted in Pusa during spring season of 2016-17, to evaluate 7 sugarcane genotypes (‘CoP 11436’, ‘CoP 11437’, ‘CoP 11438’, ‘CoSe 11451’, ‘BO 130’, ‘CoSe 95422’ and ‘BO 153’) in early maturing group and 7 sugarcane genotypes viz., ‘BO 155’, ‘CoSe 11453’, ‘CoSe 11454’, ‘CoSe 11455’, ‘BO 91’, ‘CoP 9301’ and ‘CoSe 92423’ in mid late maturing group at 120 cm row spacing. In early group, genotype ‘CoP 11436’ produced the higher tillers (1, 38000/ha), millable canes (1, 04800/ ha), cane (88.2 t/ha) and sugar yield (11.1 t/ ha). Genotype, ‘CoP 11438’ showed the higher brix (20.6) and pol (18.39%) per cent juice among test genotype, followed by standard check ‘BO 153’. Under mid late maturing group, higher germination count (46.2%), tillers (1, 52, 100/ha) and millable canes (1, 07800/ ha) was noticed due to the genotype ‘BO 155’ which was followed by the standard check ‘CoSe 92423’. However, ‘CoSe 11455’ recorded the highest cane (103.7 t/ha) and sugar yield (13.18 t/ha), followed by ‘BO 155’ in case of cane yield and CoSe 11453 in sugar yield. Among mid late genotype ‘CoSe 11453’, ‘CoSe 11454’ and standard check ‘CoP 9301’ obtained similar brix values of 20.7%. However, standard check ‘CoP 9301’ was found significantly superior to ‘BO 155’ with respect to pol and commercial cane sugar percent.
