FAMILY SELECTION IN SUGARCANE POPULATIONS AS AFFECTED BY GENOTYPES X ENVIRONMENTS INTERACTION

Abstract

The present investigation included two experiments were carried out during three growing seasons (2011/12 to 2013/14) at three locations, i.e. Kom Ombo Agricultaral Research Station, Aswan Governorate latitude 24° 15o N (L1), Mattana Agriculture Research Station, Luxor Governorate latitude 25o 36o N (L2) and Shandweel Agricultural Research Station, Sohag Governorate latitude 26o 33o N (L3). I- First experiment (base populations): The basic materials used in this study consisted of five sugarcane populations consisted of 206 clones, were G.85-37 X self. (population I) number of clones 41, G.85-37 X Phil.8013 (population II) number of clones 27, G.85-37 X Bo.3 (population III) number of clones 51, Cp.57-614 X G.85-37 (population IV) number of clones 48 and EH.94-181-1 X Cp.31-294 (population V) number of clones 39 to select the best clones that could outyield the commercial check cultivar GT. 54-9 at two locations i.e. Shandweel and Kom-Ombo in 2011/2012 growing season. Based on the results obtained from the first experiment (base populations) a total of sixteen clones of five populations were selected as follows: population I (2 clones); population II (4 clones); population III (2 clones); population IV (6 clones) and population V (2 clones) and planted in the second experiment.
