Cotton High Speed Phenotyping

Thematic Series Call For Paper

Coordinator: Professor Eric F. Hequet, Texas Tech University, USA; Dr. Glen Ritchie, Texas Tech University, USA

High speed phenotyping is critical to improve cotton research and production. It can be applied to large scale commercial fields, research fields, breeding lines, and even at the individual plant level. The main goals are to improve yield, fiber quality, stress and disease resistance, etc… Recently, advances in high speed phenotyping in cotton have been achieved. The Journal of Cotton Research is hosting a thematic series on this topic. The research community is encouraged to share original findings, methodology, results, databases, and/or software and opinions.

Scopes that may be covered in the submissions may include, but are not limited to the following:
1. Platform design: air-based and/or land-based;
2. Data capture and processing: sensors (RGB, IR, multispectral, sonic, etc.), integration of multiple sensors, information processing technologies;
3. Data analysis and Metadata: analysis of very large data sets, validation with ground truth, practical application examples (breeding programs, site specific irrigation scheduling, etc.).

Submission Deadline: April 30, 2019

Evaluation of genetic diversity in short duration cotton (Gossypium hirsutum L.)

[Background] Cotton (Gossypium hirsutum L.) is an important fiber crop in Bangladesh. Genetic diversity among the genotypes of a germplasm has a great importance for cotton breeding. An experiment was carried out at the experimental field of Cotton Research, Training and Seed Multiplication Farm, Sreepur, Gazipur during the cropping season of 2015–2016 with 100 genotypes to evaluate genetic diversity of cotton genotypes for short duration using field performance.

[Results] The genotypes under study were grouped into ten clusters through multivariate analysis using GENSTAT-5. Cluster III contained maximum number of genotypes (16) while cluster X contained the least number of genotypes (7). The inter cluster distances were larger than intra cluster distances in all cases suggesting wider genetic diversity among the genotypes of different clusters. The maximum and minimum inter cluster distances were observed between clusters II and V (10.78) and clusters VIII and IX (3.30), respectively. The results indicated diverse and close relationship among the genotypes of those clusters. Earliness index, single boll weight and days to boll opening showed the higher contribution to the genetic divergence among 19 characters.

[Conclusion] Based on the results of genetic diversity and earliness index, the genotypes from cluster II could be used as parent in hybridization program for the development of short duration cotton variety.
