“…3). Similar findings were reported by Gowda et al [19] as heritability is a good index of transmission of characters from parents to its progeny; Alam et al [20] for number of millable cane; Ranjan and Kumar [21] and Dereje. S. [22] for Cane diameter at harvest (cm) and CCS yield.…”

Sugarcane varietal development is frequently aimed at increasing yield and sucrose quality. Effective crop genetic evolution requires knowledge of the numerous traits that contribute to the present diversity by genetic analysis. Keeping in view, this experiment was conducted using a randomized block design with three replications and the trial consisted of nine mid-late sugarcane genotypes. Data on cane yield and quality traits were used to estimate the genetic variability parameters, heritability, and genetic advance (GA). Analysis of variance revealed highly significant and significant differences for all studied traits. Evaluated characters exhibited different levels of variability, heritability, and genetic advance among the studied genotypes. Low to high phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) were recorded. The moderate GCV and PCV values were found particularly for Sugar Yield at harvest (18.09% and 21.64%) and Cane Yield at harvest (16.62% and 20.14%) respectively, whereas the lowest GCV and PCV (1.43% and 2.26% respectively) manifested for Purity at the 12 months stage. The highest broad sense heritability value manifested for Pol in juice at 12 months stage (%) (86.47%) followed by CCS at 12 months stage (%) (85.43%), while the lowest heritability (35.00%) revealed only for Germination % at 30 DAP. In the present study, high heritability and genetic advance as a percentage of the mean (>50) was recorded for Millable canes at harvest (000/ha) and single cane weight at harvest (kg) indicating a predominance of additive gene action for these characters. Therefore the result of this study suggests the existence of variability for cane yield and quality traits in these sugarcane genotypes, which should be exploited in future breeding.

“…In present study high genetic advances (>20%) were revealed for Plant height at harvest (cm), Cane yield at harvest (t/ha), Millable canes at harvest (000/ha) and Tillers at 120 DAP (000/ha), while others traits manifested low genetic advance (<10%)" (Table 3). [23]; Ranjan and Kumar [21]…”

“…Similarly, for cane diameter, moderate PCV (13.329) and GCV (10.403) estimates with high H 2 b (60.922 %) and moderate value of GAM (16.727 %) were recorded. Similar results had been previously reported by Ranjan and Kumar, (2017) (44.657 %) were also recorded high. For these traits, all the four estimates were also observed as high earlier by Anbanandan and Eswaran (2018).…”

An experiment was conducted to explore variation and the association among 13 sugarcane yield and juice quality attributes through correlation and path coefficient analysis. Phenotypic coefficient of variation (PCV) was found higher than genotypic coefficient of variation (GCV) for all the traits. Moderate to high GCV, PCV along with high heritability and genetic advance were recorded for several agronomic traits, indicated wider range of variability in population. Results showed that cane yield exhibited highly significant positive correlation with CCS yield, number of millable canes, number of tillers, single cane weight, germination per cent, cane height and cane diameter at both genotypic and phenotypic levels. Path analysis revealed that three characters namely CCS yield, sucrose per cent and number of millable canes exerted positive direct effect on cane yield at both the levels. CCS yield exerted highest indirect effect on cane yield via number of millable canes, single cane weight and number of tillers on cane yield. These indirect effects could be the major cause of concern for the positive correlation of these characters with cane yield thus should be considered at the time of selection.

“…(2017),Patil et.al. (2017) andRanjan and Kumar (2017) have already been reported the significant differences among the genotypes for all the characters.Exploitation of heterosis largely depends on the degree of genetic divergence between the parents selected for breeding programme. Genetically diverse parents are expected to yield superior hybrids.…”

Fifteen early maturing sugarcane clones including two checks were planted in Randomized Block Design with three replications during spring season 2017 at research farm of RPCAU Pusa to evaluate the variability and clustering pattern for cane yield and yield attributing traits. Observations were recorded for the eighteen traits viz., germination % at 45 days after planting, number of shoots at 120 days, plant height at 150, 240 days and at harvest, cane diameter at harvest, millable canes at harvest, single cane weight at harvest, brix, pol, purity and ccs at 8 and 10 th month stage, sugar yield and cane yield at harvest and after its statistical analysis, all the characters were found differed significantly for all the genotypes. All the early maturing sugarcane clones were grouped into four distinguished clusters among fifteen genotypes.Cluster I contained maximum number of clones (6) followed by cluster IV (4), cluster III (3) and cluster II (2). Maximum intra-cluster D 2 distance was observed in cluster I and maximum intercluster D 2 distance was observed between cluster II and cluster IV. The trait, Pol percent at 10 th month stage showed maximum character contribution percent towards divergence followed by sugar yield at harvest, cane yield and brix at 10 th month stage. Keeping all the genetic information and their conclusive interpretations, it can be safely concluded that to attained these objectives, bi-parental mating or poly-cross technique used for developing high yielding sugarcane clones involving genotypes belonging to cluster II and cluster IV as well as cluster III and cluster IV may be tried.
