1. Varietal and seasonal variation of "motes" in upland cotton

Author:
Rea, H.E.
Source:
Agronomy journal 1929 v.21 no.4 pp. 481-486
ISSN:
0002-1962
Subject:
Gossypium hirsutum; abnormal development; seasonal variation; cultivars; Texas
Abstract:
... The results of the study on the percentage of the motes made in 16 varieties grown in 1925 and 1926 justify the following conclusions: 1. The occurrence of motes in the commercial varieties of cotton studied was very common. In a study embracing two years, 1,323 plants were examined and only 2 failed to have any motes. 2. The percentage of motes occurring in the commercial varieties of cotton stud ...

Gossypium hirsutum; cotton; crop production; cultivars; defoliation; early development; fiber quality; fruiting; fruits; harvest date; insect control; rain; soil texture; Texas
Abstract:
... The short-season concept (early defoliation and early harvest) offers, perhaps, the greatest potential for increasing the efficiency of cotton (Gossypium hirsutum L.) production and for minimizing insect control requirements in the Lower Rio Grande Valley of Texas. Early defoliation also allows harvesting during the most optimum period in relation to expected rainfall. The fruiting, earliness, yie ...

Abstract:
... Recent studies have indicated that cottonseed (Gossypium hirsutum L.) germination and seedling vigor are more closely related to seed density than to any other physical properties such as size or weight. This study was undertaken to determine the physical and chemical differences among seed of different densities within a cultivar and among seed of the same density between cultivars. The primary o ...

Abstract:
... Soil and plant analyses are diagnostic tools with which the adequacy of soil fertility programs can be evaluated. Plant tissue analysis provides information on what the plant is actually obtaining from the soil and provides a basis for refining the soil fertility program and thus could become an important management tool in crop production. However, as with any analysis, results are of limited val ...

Abstract:
... The production of fruit on upland cotton (Gossypium hirsutum L.) varies with environment, cultivar, and management practices, including irrigation. Yield increase in response to irrigation is a combination of additional boll production on the plant and differences in the size of individual bolls. Previous research on this subject is incomplete. The purpose of this research was to compare the effec ...

Abstract:
... In the semiarid Texas Rolling Plains, the growth and yield of cotton (Gossypium hirsutum L.) is driven by the amount of water available to the crop through irrigation and precipitation. A field study was conducted in 2012 and 2013 at Chillicothe, TX, to investigate the growth, yield, water use efficiency (WUE), and spectral reflectance responses of cotton. A split-split plot design with three repl ...

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 ...

... 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 ...
