Evaluation of mid-late sugarcane clones for their yield and quality characters in advanced selection stage in plant and ratoon crops

Abstract

Comparative performance of six mid late maturing sugarcane clones were tested along with two standards in Advanced Varietal Trial in three crop cycles viz., plant I, plant II and ratoon at Sugarcane Research Station, Tamil Nadu Agricultural University, Sirugamani. Cane yield, sugar yield and seven other attributing traits like number of millable canes, cane height, cane thickness, internode length, Brix %, Pol % and commercial cane sugar % (CCS %) were studied in every crop cycles. The data observed in all three crop cycles were analysed separately and finally the data were pooled to carry out a pooled analysis. Significant differences were noticed among the test clones and standards for cane yield, sugar yield and its contributing parameters in plant I, plant II, ratoon and pooled analysis. Among the six clones tested, two test clones viz., Si 2009-13 and Si 2009-33 recorded significantly higher cane yield in plant I, II, ratoon and pooled analysis. The clone Si 2009-13 recorded significantly higher sugar yield in plant II, ratoon and pooled analysis. Similarly, the test clone, Si 2009-33 recorded significantly higher sugar yield in plant I, II, ratoon and pooled analysis. These two clones also recorded significant performance in most of the characters studied in all crop cycles and pooled analysis. Hence, these two clones viz., Si 2009-13 and Si 2009-33 were selected and promoted to multi-location trial in various sugarcane research stations to judge the cane yield and sugar yield in diversified environment.
