However, some past studies did not support the present results and mentioned the variation for monopodia among various cotton populations but negative impact on seed cotton yield in upland cotton (Iqbal et al., 2003; Alishah et al., 2008; Batool et al., 2010).
For monopodia per plant, maximum inbreeding depression (83.33%) was observed in F3 population CIM-446 x CIM-554, while the minimum value was exhibited by SLH-284 x CIM-473 (6.45%) (Fig.
Present results revealed that in inheritance of monopodia, the genetic variances played an important role and there is an opportunity in the said genotypes for further decrease in vegetative branches through intensive selection.

Ray and Richmond (1966) reported that first fruiting branch node number of monopodia
and bolls per vegetative branches are the important attributes while Godoy (1994) emphasized on measuring the plant height days to first flower and first open boll for assessing the cotton genotypes for earliness.
Effects of early flower bud loss and mepiquat chloride (MC) applications on yield distribution of lower and mid-level sympodia and monopodia of cotton cv.
Interactions between bud loss treatments and MC applications occurred for yield and yield components within Zone 3 sympodia and monopodia. The greatest monopodial yield occurred with the LRM treatment and moderate early bud loss.
List of abbreviations used: NTFFB= Nodes to 1st fruiting branch MPP= Monopodia per plant SPP= sympodia per plant PH= Plant height BWT= boll weight SL= Staple length FF= fiber fineness FS= Fiber strength EI= earliness index GOT= Ginning out turn DFS= days to 1st square DFF= days to 1st flower CLCuV= Cotton leaf curl virus GCV= genotypic coefficient of variation PCV= phenotypic coefficient of variation
(2000) studied the earliness and agronomic traits of upland cotton cultivars using correlation analysis and found that monopodia had a negative direct effect on yield.
Location of boils on sympodia and monopodia
determined from mapping of cotton plants grown at 2 and 12 plants [m.sup.-2] 1992 and 1993 at Clayton, NC.
Mean performance of cotton genotypes for monopodia
plant-1 as affected by environments
The few bolls from monopodia
were determined to be FP1, FP2, or FP3 and combined with those groups.
