Assessment of Variability in Sugarcane (Saccharum Spp.) Seedlings of Different Crosses for Quantitative Traits

Any breeding program's effectiveness depends on a number of variables and one of those variables that maximises the benefits of selection is the amount of variability present in the genotypes.Thus, study was carried out with the aim of estimating variability in the sugarcane seedlings.The sugarcane seedlings obtained from three different crosses are planted at Sugarcane Research Institute, Pusa, Bihar India in an unreplicated trail along with a check.The analysis was carried out using Windostat and R studio software.The one-way analysis of variance studies resulted in identifying highly significant variation within and among the crosses for most of the traits.Through general studies it was found that CoP 11437 GC had obtained highest mean over the check Rajendra Ganna 1 for the characters such as plant height, number of shoots per clump, leaf length, cane diameter, number of millable canes, and brix at 10 th month.For the character brix at 10 th and 12 th months a positive skewness and negative kurtosis was observed which indicates the values are concentrated on right of mean for skewness and the distribution of progeny showed higher peaks for kurtosis.High variability was observed among the seedlings of each cross for traits like brix value at 10 th and 12 th months and cane yield per clump as these traits showed high range difference.
