Development of high yielding sugarcane varieties for rainfed areas: Yield multilocation trial of promising sugarcane clones

Abstract

Two promising new sugarcane clones PS 05-370 and PS 06-103 along with control varieties were evaluated for the stability of their performance at ten locations across three years. Parameters observed include cane yield in tonnes cane per hectare (TCH), sugar content or commercial cane sugar (CCS) in %, and sugar yield in tonnes sugar per hectare (TSH). Significant differences were observed in genotypes and locations x genotypes interactions for TCH, CCS and TSH. Additive Main Effect Multiplicative Interaction (AMMI) stability analysis showed that these two sugarcane clones are specific location; grown in inceptisol soil with C3 climate type (Oldeman), sugar productivity (TSH) of PS 05-370 and PS 06-103 increased by 17-21%, compared to standard control variety PS 881. These two promising clones are early to mid maturing varieties and therefore, are recommended to be harvested earlier, to fill up the need for crushed material in the beginning of the milling season.
