Sugarcane yield components and sugar content in ROC22 progeny populations [Full subscriber]

Abstract The objectives of this study were to find the effect of ROC22 as a parent on cane yield and sugar content in progeny populations (PPs) by crossing ROC22 as a female or male, and to evaluate its PPs for selection. ROC22 was crossed with 18 other sugarcane (Saccharum spp.) parental varieties or clones and 21 PPs were produced by 6 crosses with ROC22 as a female and 15 as a male. Seven traits were collected from a family trial containing ROC22 as control cultivar: millable stalks per stool (MS), plant height (PH), stalk diameter (SD), sugar content (SC), single…
