An approach for developing compactness measurement indices in cotton (Gossypium spp.)

High density planting with compact genotypes proved, as high potential system of cotton cultivation. There is a need to develop proper indices measure compactness in plant, necessitated for screening genotypes. Compactness measured using ((R× r) × √ h) was identified an efficient method, based on that NSBT 108 , PAU1 OUAT Bt 2 CICR- K 34007 and CICR-CSH 19-2 were Compact Efficiency Index (CEI 1) suitable measuring efficiency compactness.
