1. Predicting Cotton Crop Boll Development

Author:
D. F. Wanjura; O. H. Newton
Source:
Agronomy journal 1981 v.73 no.3 pp. 476-481
ISSN:

Subject:
Gossypium hirsutum; air temperature; bolls; cultivars; lint cotton; prediction; High Plains (United States); Texas
Abstract:
... Cotton (Gossypium hirsutum L.) lint development on the Texas High Plains frequently spans periods of low temperature that reduce yield and quality. We conducted a study in 1977 to 1979 at Lubbock, Texas, to develop a procedure for estimating the level of crop lint maturity at any time after boll setting begins. The procedure includes a model that uses the initiation date for each 1/10 increment of ...

Subject:
Gossypium hirsutum; dry matter partitioning; early development; cultivars; source-sink relationships; bolls; stems; leaves; field experimentation; isotope labeling; carbon; starch; sexual reproduction; photosynthates; Texas
Abstract:
... Differences in source-sink relationships between short- and long-season cotton (Gossypium hirsutum L.) cultivars, the contribution of main stem leaves to boll growth, and the distribution of nonstructural carbohydrates late in the season are not well understood. This study compared the cultivars Tamcot CAMD-E (a short-season type) and Stoneville 213 (a long-season type) for two seasons in the fiel ...

Subject:
cotton; weight; cultivars; flowering; staple (fibers); Gossypium hirsutum; fiber crops; crop yield; genotype; length; genetic variation; heritability; bolls; Texas
Abstract:
... Advanced Fiber Information System (AFIS) mean fiber length by weight (L(w)), fiber length development period (FLDP), and average daily fiber length growth rates (ADGR) were determined for four experimental strains and three cultivars of upland cotton, Gossypium hirsutum L., in 1998 and 1999 in College Station, TX. TAM 94L-25 and TAM 94M-14, near-long staple sib lines developed by the Texas Agricul ...

Gossypium hirsutum; bolls; branches; cotton; cultivars; drought; fruiting; heat; irrigation rates; micronaire; High Plains (United States); Texas
Abstract:
... The boll distribution characteristics of upland cotton (Gossypium hirsutum L.) cultivars are related to cotton maturity and can interact with environment and management practices to determine yield and fiber quality. The boll distributions of six cotton cultivars under four irrigation levels were compared in 2011 and 2012 on the Texas High Plains. In 2011, a year of severe drought and heat, all cu ...

5. Single and Multiple In-Season Measurements as Indicators of At-Harvest Cotton Boll Damage Caused by Verde Plant Bug (Hemiptera: Miridae)

Journal of economic entomology 2013 v.106 no.3 pp. 1310-1316

Subject:
Creontiades; Gossypium hirsutum; bolls; cotton; cultivars; insects; models; pest monitoring; plant damage; plant response; regression analysis; Texas
Abstract:
... The ability to monitor verde plant bug, Creontiades signatus Distant (Hemiptera: Miridae), and the progression of cotton, Gossypium hirsutum L., boll responses to feeding and associated cotton boll rot provided opportunity to assess if single in-season measurements had value in evaluating at-harvest damage to bolls and if multiple in-season measurements enhanced their combined use. One in-season v ...

6. The impact of fiber maturity on estimating the number of cotton (Gossypium hirsutum L.) fibers per seed surface area

Gossypium hirsutum; advanced fiber information system; bias; bolls; branches; computer software; cultivars; density; environmental factors; fiber quality; field experimentation; fruiting; growing season; lint cotton; maturity stage; scanners; screening; seeds; selection criteria; surface area; Texas
Abstract:
... The number of fibers per seed surface area (fiber density) is a selection criterion used to improve cotton fiber quality and yield simultaneously in cotton breeding programs. However, the parameters utilized to estimate fiber density are calculated from fiber quality attributes that are sensitive to environmental variations, especially fiber maturity. Fiber maturity is one of the most important fi ...

Abstract:
... The Texas High Plains often has extended periods between rainfall events, which can lead to a reduction in the yield and fiber quality of cotton (Gossypium hirsutum L.). It is known that cultivated cotton suffers from low levels of genetic diversity due to the over-use in breeding of similar gene pools, which may hinder breeding for drought tolerance. In this study, for the first time the novel va ...
