Genetic assessment in early clonal population in sugarcane (Saccharum officinarum L.) for productivity traits and resistance to foliar diseases
The study evaluated 557 progenies from commercial/near-commercial crosses, along with eight commercial checks, for productivity traits and resistance to foliar diseases in the clonal-I generation at ARS Sankeshwar during the 2022-23 season in an augmented design. The results revealed significant var...

| description | The study evaluated 557 progenies from commercial/near-commercial crosses, along with eight commercial checks, for productivity traits and resistance to foliar diseases in the clonal-I generation at ARS Sankeshwar during the 2022-23 season in an augmented design. The results revealed significant variability within and between families, heritability and genetic advance for all traits. Clones such as SNK 190023, SNK 191722, SNK 190362 and SNK 191801 recorded significantly higher cane yield besides showing high resistance (HR) to foliar diseases such as brown rust, red leaf spot, eye spot, brown spot and pokkah boeng in comparison to the checks Co 09004 (early) and Co 86032 (mid-late). Families F3 (CoVC 14062 × Co 775), F5 (CoVC 14062 × CoT 8201), F8 (Thirumadhuram × CoPant 97222), F12 (CoC 671 × 85 R 186), F14 (Co 86032 × CoSe 92423), F15 (CoVC 14062 GC), and F44 (Co 99004 GC) exhibited significant superiority over the check Co 86032 for cane yield, while CoVC 14062 × CoT 8201 and Co 99004 GC showed higher selection rates and high resistance to brown rust (100%), red leaf spot (84%), and Pokkah boeng (70%) suggesting their potential for use in future breeding programs aimed at improving sugarcane productivity and disease resistance.
