Sugar Cane
  The present study was carried out at breeding station of Hawamdia Sugar Cane Research Station (HSCRS), to study the response of the 36 genotypes of sugarcane the artificial flowering. And estimate the genetic potential of six families of sugarcane during the cultivation in the first selection stage. The investigated traits were stalk length , stalk diameter, stalk weigth, stalk number/stool, stool yield, brix and pith. The results showed significant differences among the selected genotypes under the investigated photoperiod treatments. However, it was apparent that under 90 day photoperiod treatment, 11 genotypes revealed differential response to development stage, flag stage and full emergence stage. while 10 genotypes responded under 75 day photoperiod treatment. 7 genotypes responded under 105 day photoperiod treatment. 3 genotypes responded under 60 days and 13hr treatment, 2 genotypes responded under 13.15hr treatment and 5 genotypes responded under 90 days. Analysis of variance of six bi-parental crosses revealed significant differences among evaluated full-sib families for all studied traits. The variation among families were higher in magnitude than within family for all traits. 14 full-sib families, i.e. 94/181-1x 87/29-1, 94/181-1 x EN3-4, 94/181-1 x EH16-1, 82/4-21 x 2006/170-40,82/4-21 x EH128-2,82/4-21 x IK84,82/4-21 x B36-21,82/4-21 x EI45-43,PH7115 x B36-21,2004/119-2 x 2005/287-1,2004/119-2 x CP82/1592,EN3-4 x CP57-614,G10 x 2006/294-11and G10 x PR1013were the best families for most studied characters.
