Description A study Was conducted during 1994 -96 to evaluate 16 early maturing high sugar genotypes in plant crops for3 quality traits - brix, purity and sugar content at 4 sampling dates in October, November, December and January toassess the genetic variances, heritability, genetic advance over the mean, correlation coefficient among the characters ateach· sampling date and repeatability of quality traits between sampling time and maturity. Results showed that thegenetic variances for these traits were largest at the early maturity stage (October). The broad sense heritability, geneticadvance over the mean and correlation between 3 sucrose related traits were also highest at early maturity stage (October)and lowest at late maturity stage (January/February). Repeatability of quality traits between sampling time and maturitywas smallest but highly significant at early maturity stage and highest at the late maturity stage. The study indicates thatselection for the sucrose related traits will have higher expected genetic gains at the early maturity stage than selectiondone at other maturity stages. Genotypic differences between clones were more pronounced during this(October) forquality traits and this is very important and critical time for selection of period desirable early maturing high sugargenotypes in Uttar Pradesh which lies in the subtropical part of india .
