Description The present investigation entitled “Identification of sugarcane clones suitable for delayed harvest and crushing” was conducted at Agricultural Research Station, Perumallapalle, Chittoor, Acharya N.G. Ranga Agricultural University, Andhra Pradesh, during 2011-2012. The field experiment was laid out in Randomized block design (RBD) with three replications. Five promising early sugarcane clones (2006 T3, 2006 T8, 2006 T19, 2006 T23 and 2006 T36) from yield trials along with two checks (Co C 671 and Co 94008) were evaluated.
The data on different growth parameters viz., Germination per cent, Plant height, SCMR values and Leaf area index were recorded at different crop growth periods. The highest germination count was recorded with 2006 T36 followed by Co C 671 and Co 94008, whereas the lowest count was recorded with 2006 T23. Among the clones 2006 T3 and 2006 T36 recorded the highest plant height at different crop growth periods (90, 120, 240 DAP and at harvest) along with two standards (Co C 671 and Co 94008), while the clone 2006 T23 recorded the lowest plant height.
The highest SCMR values and LAI was recorded with Co C 671, Co 94008 followed by 2006 T36 and 2006 T3 at different crop growth periods (60, 90, 120 and 150 days), whereas, the clone 2006 T23 recorded the lowest SCMR and LAI values.
The data on cane weight and juice quality parameters viz., per cent juice sucrose, CCS %, purity %, pH and reducing sugars were recorded at
xiv
24 hrs interval from 0-120 hrs after harvest in every month i.e., from November (10th month) to February (13th month).
The clones Co C 671 and Co 94008 recorded the highest per cent juice sucrose, commercial cane sugar %, purity % and cane weight followed by 2006 T36 and 2006 T3, whereas the clone 2006 T23 recorded the lowest among all the clones. All the quality parameters viz., percent juice sucrose, commercial cane sugar %, purity % and cane weight were decreased with increase in staling period, whereas reducing sugars were increased with increase of staling period in each month.
The clones Co C 671, Co 94008 followed by 2006 T36 and 2006 T3 recorded the highest per cent juice sucrose, commercial cane sugar %, purity %, cane weight and lowest reducing sugars at all staling periods(0-120 hrs) which indicates their tolerance to post harvest deterioration.
The data on juice quality parameters viz., per cent juice sucrose, commercial cane sugar %, purity %, cane weight and reducing sugars recorded at different months of crop age (10th, 11th, 12th, 13th and 14th month) for their suitability to delayed harvest indicated that among the clones studied 2006 T36 and 2006 T3 recorded the highest juice per cent sucrose, commercial cane sugar %, purity % and cane weight at all months of harvest viz., 10th month (November), 11th month (December), 12th month (January), 13th month (February) and 14th month (March) along with Co C 671 and Co 94008, while the lowest was recorded in 2006 T23.
All the quality parameters viz., per cent juice sucrose, commercial cane sugar %, purity % were decreased with increase of crop age. However, the highest levels were recorded at 12th month (January) due to diurnal effect. The lowest quality parameters and cane weight were recorded in the month of March.
The clones viz., 2006 T36 and 2006 T3 recorded the highest per cent juice sucrose at all months of harvest (10th, 11th, 12th, 13th and 14th months) indicating their tolerance to delayed harvest, while the clone 2006 T23 recorded the lowest.
The data recorded on different yield attributes viz., cane diameter (cm), cane length (cm), number of millable canes and cane yield at harvest showed that 2006 T36 and 2006 T3 recorded the higher cane yields along with checks, while the clone 2006 T23 recorded the lowest cane yield.
Based on results from the present study, it was found that the clones 2006 T36 and 2006 T3 recorded the highest juice per cent sucrose, commercial cane sugar %, purity % and cane weight at all staling periods (0 to120 hrs) and at different months (10th, 11th, 12th,13th and 14th months) of crop harvest. Thus, it is concluded that these clones were found to posses tolerance to post harvest deterioration and delayed harvest. Therefore, these clones can be recommended for general cultivation under delayed harvest and also for delayed crushing.
