Performance of Mid-late Sugarcane Clones in AICRP(S) Trials for Quality Traits and Red Rot Resistance

Abstract

A field experiment was conducted to evaluate the performance of mid-late sugarcane pre-release clones for CCS yield and its contributing characters along with red rot disease resistance. Observation on brix per cent, sucrose (%), purity (%), extraction (%), fibre (%), CCS (%), cane yield (t/ha), and CCS yield (t/ha). From the results, it could be concluded that the mid-late maturing clone, CoC 14337, was found to be the best among the test clones for sucrose per cent and CCS yield along with resistance to red rot disease. Another clone, CoA 14323, was the next-best entry, with higher CCS yield, sucrose percent and red rot resistance, compared to the better standard. As a result, clones CoC 14337 and CoA 14323 were identified as the promising entries (clones) and could be forwarded for further yield evaluation trials before being released as a new sugarcane variety suitable for East Coast Zone of India.

Evaluation of Sugarcane (Saccharum spp. hybrids) Clones for Yield and Quality and Its Contributing Traits

“…Among the clones evaluated, three clones viz., CoC 13336, CoV 13356 (90.42%) and CoC 13337 (90.07%) recorded superior performance over the better standard CoC 01061 (89.95%). Similar reports already reported by [14].…”

“…[17]. "The higher CCS yield of clones may be attributed to relatively more average cane yield and subsequent commercial cane sugar percentage" [14]. There are varieties capable of giving higher cane yields and fairly good recovery leading to higher per acre sugar production.…”

Yield, Quality and Disease Resistance of Sugarcane Clones: A Field Evaluation

“…Among the test clones, onlytwotest clones CoC 15336 and CoC 15338were recorded superior performance over the better standard CoC 01061, which recorded 17.83 per cent". [10] The results are almost similar as demonstrated by [19].…”

“…Among the clones evaluated, none of the clones were recorded higher germination percentage over the standard CoC 01061 (59.42%). The germination percent directly influences the number of tillers and shoots and similar reports on germination percent for early sugarcane clones by [11].…”

“…The variation in cane yield and yield components among genotypes may be attributed to genetic differences". [10] The data on cane yield and yield contributing traits are furnished in Table 1 and quality characters were presented in Table 2.…”
