BOLL

A gene on chromosome 2q33 that encodes a putative RNA-binding protein which may be required during spermatogenesis. BOLL is thought to act by binding to the 3'-UTR of mRNAs and regulating translation; it is testis-specific and interacts with DAZ1 and DAZL.

From Table 2 it is clear that the highest (34.37) genotypic coefficient of variance recorded for lint mass per boll while the highest (40.34) phenotypic coefficient of variance for the monopodial branches per plant.
With respect to boll weight, greater genetic variances were displayed by less than half of the progenies as compared to their corresponding environmental variances.
The spatial and temporal distribution of reproductive structures [cotton squares of large (68mm diameter), medium (3-6mm diameter), and small bolls size (5-8mm diameter)] fallen on the soil damaged by boll weevil between cotton rows were determined in a randomized block design with a factorial arrangement of 4x3, represented by soil surface tracks located at 1-11cm, 12-22cm, 23-33cm, and 34-44cm away from planting row on cotton plants at 70, 85, and 100 days of age.
The significant impact of farm yard manure levels on boll weight was seen with respect to different tillage technologies.
But extreme heat in late sown plots also results in photosystem inhibition (Schrader et al., 2004), low biomass accumulation (Reddy et al., 1995) and male sterility which cause more flower and boll shedding (Fisher, 1975).
Pneumatic harvesters removed cotton fiber from the bolls with suction or a blast of air.
After maturity, all the F1 bolls along with selfed seed of parents were harvested to complete the experimental seed material for replicated trial of F2s in kharif 2008.

The great genetic variability and phenotypic plasticity of the boll weevil makes it able to adapt to a wide variety of environmental conditions, allowing the expansion of its geographical distribution beyond its center of origin (Central America) (Showler, 2009).
great Father of Waters, I grew up, beside the prickly boll of white,
(2005) conducted an experiment regarding the effect of sowing dates on the population of boll weevils, they concluded that squares damage of boll weevils were 44-56% more abundant in later planted treatments than in the earlier planted treatments.
At its annual Ag Issues Forum, Bayer CropScience (BCS) presented Bryan Boll with the 2014 Young Farmer Sustainability Award.
