Identification of resistance sources for sesame phyllody under epiphytotic conditions in India
Sesame crop is susceptible to phyllody disease caused by phytoplasma leading to major yield losses across India and worldwide. Screening of sesame genotypes against phyllody is essential to identify reliable sources of resistance. The experiments were conducted in phyllody hot spot research field with different dates of sowing in 2018–2019 to identify the effective season for screening against sesame phyllody and durable source of resistance. The results from our study recorded that phyllody incidence was more prevalent during July sowings when compared to November, August and January. Furthermore, field screening for continuous three years (2019–2021) recorded phyllody tolerance in three sesame genotypes (GTG-30, G-10-P1-P5-P3 and G-10-P1-P5-P6) along with resistant check GT-10. Sesame genotype, RJR-170 was found to be highly susceptible among all genotypes. The leafhopper population ranged from 0.2 to 0.3 among genotypes showing tolerance. Our findings could be successfully exploited in phyllody resistant breeding programmes.
期刊介绍：
Genetic Resources and Crop Evolution is devoted to all aspects of plant genetic resources research. It publishes original articles in the fields of taxonomical, morphological, physiological, biochemical, genetical, cytological or ethnobotanical research of genetic resources and includes contributions to gene-bank management in a broad sense, that means to collecting, maintenance, evaluation, storage and documentation.
Areas of particular interest include:
-crop evolution
-domestication
-crop-weed relationships
-related wild species
-history of cultivated plants including palaeoethnobotany.
Genetic Resources and Crop Evolution also publishes short communications, e.g. newly described crop taxa, nomenclatural notes, reports of collecting missions, evaluation results of gene-bank material etc. as well as book reviews of important publications in the field of genetic resources.
Every volume will contain some review articles on actual problems. The journal is the internationalized continuation of the German periodical Die Kulturpflanze, published formerly by the Institute of Plant Genetics and Crop Plant Research at Gatersleben, Germany.
All contributions are in the English language and are subject to peer reviewing.
