Abstract
The present study was carried out at Regional
Agricultural Research Station, Anakapalle (2018-19 to 2019-20) in RCBD with two
replications in a gross plot size of 8mtx0.8mx8R=51.20m2 and net plot size of
8mx0.8mx6R=38.40m2. All recommended package of practices were followed. The
clone 2009A252 recorded significantly higher tiller population at 120DAP(141.28
thousands/ha, number of millable canes(132.00thousands/ha),cane
yield(143.67t/ha) and sugar yield(24.59t/ha) followed by
2014A210(135.70thousans/ha,128.33 thousands/ha,131.33 t/ha and 22.32t/ha
respectively) and 2015A222 (133.00 thousands/ha,120.00 thousands/ha,126.00 t/ha
and 22.27t/ha respectively) and found to be significantly superior over the
standard,87A298(118.30 thousands/ha,105.33 thousands/ha,110.67 t/ha and
17.34t/ha respectively. The clone,2015A152 recorded significantly higher brix
per cent(24.00),sucrose(22.50%),CCS (18.67%),juice extraction per cent(66.23)
and fibre per cent(14.22) followed by 2015A199 (23.05%,21.60%,17.72%,62.33% and
14.30% respectively) and 2015A187(23.02%,21.57%,17.69%,60.33% and 14.30% respectively) when compared to standard,87A298(21.05%,19.55%,15.67%,58.67%
and 13.96% respectively). Five clones viz., 87A298,2006A64, 2009A107,
2014A210 and 2015A183 were rated as less susceptible (LS) to early shoot borer
with mean percent damage. A biplot describing the traits projection on the
first three principal components describing the traits in Sugarcane of 71.93%
of total variation represented that yield and quality contributing characters
were positively associated among themselves. Similarly, characters such as brix
%, CCS% and Sucrose % showed a positive correlation since the angle between
vectors is less than 900. All the traits had positive vectors on
PC1. The biplot ordination in two or three dimensions highlighted the relations
among the traits. Identification of clones with high yield potential and
quality traits coupled with resistance to pests and diseases is essential in
the development of varieties. The promising genotypes represent valuable
genetic resources for future varietal improvement in sugarcane breeding programs
through targeted breeding approach
