Abstract
Thirty sugarcane clones (Saccharum spp.) that selected from six bi- parental crosses (families) along with two check cultivars (GT54-9 and Ph8013. The aims were to evaluate the performance of yield and quality traits in plant cane (PC) and first ratoon crops (FR) at the first clonal selection stage, estimate broad{u2013}sense heritability and genetic variance components and to determine phenotypic and genotypic correlation coefficients among ten agronomic characters and to analyze their interrelationships through path coefficient analysis under Upper Egypt conditions at Shandweel Agricultural Research Station, Sohag Governorate, Egypt during 2013 and 2014 harvesting seasons. Results indicated significant differences among evaluated clones for most important traits. Across plant cane and first ratoon the clones, G2009- 2 G2009-7, G2009-10, G2009-18, G2009-21, G2009-27and G2009-30, surpassed the two check cultivars for cane and sugar yields. Genotypic variance, heritability, phenotypic and genotypic coefficient of variation increased slightly from plant cane to first ratoon for the traits of number of stalks /fed and purity%. Results showed that phenotypic and genotypic correlation between cane yield and its components, viz. stalk diameter, stalk weight and number stalks/fed were highly significant in the positive direction in plant cane, first ratoon and across crops
