Abstract/Description: | Family selection has been adopted in sugarcane breeding programs as an indirect method of selection of superior clones in early stages of selection among seedling progenies. In this study, forty clones from 53 sugarcane crosses (families) were evaluated for yield and quality parameters in plant and ratoon crops at Sugarcane Breeding Institute,Coimbatore during 2005-2008 season. Families evaluated in replications and individuals selected based on visual appraisal for yield parameters from selected families. Individual selection rate within families ranged from 10- 30%. Top 30% of clones were selected from six best families viz., Co 7201 x Co 86002, Co 98010 x Co 94019, Co 86002 x Co 90018, Co 8371 x Co 86002, Co 8371 x CoC 8001 and Co 740 x Co 88025 with progressively fewer clones being selected from moderate to average families (Co 62260 x Co 6418, Co 837 x Co 94008). Individual selection within families based on brix % was best along with visual grading. In assessing the worthiness of families with old clones, parents like Co 62260 and Co 837 performed poorly even with new parents compared with crosses with new parents indicating the need for changing the base population. The study helped in generating breeding value of parents in crosses for their recycling in hybridization programme. Combined family selection and individual clonal selection in sugarcane were effective in identifying families with highest proportion of elite clones based on plant and ratoon crops performance |
