RESISTANCE OF CHICKPEA GENOTYPES FUNGAL DISEASES

Abstract

Fungal disease is an important and widespread disease in chickpeas (Cicer arietinum L.) throughout the world. The disease is especially severe in cool and humid weather. Selection for host resistance is an effective means of controlling this disease. This article has attempted to summarize the progress made in identifying sources of resistance, genetics and selection for resistance, and genetic variation among pathogen populations. Current trends in climate change towards warming require the introduction of new crops with high drought resistance into agricultural production. Chickpea is such a crop, the world's sown area of ​​which exceeds 12.5 million hectares. This article presents the results of phytopathological monitoring and immunological evaluation of 87 varieties and lines of chickpeas to fungal diseases. Of all the 86 genotypes studied on a natural and artificial infectious background, 17 samples and lines of chickpeas were selected for resistance to ascochitosis and fusarium: Ikarda 1, K 2197, Krasnokutsky 36, Zavolzhsky, Sphere, Vector, K 118, K2814, Flip 10-159C, Flip93-93C, Flip 82-150C, Flip 10-206C, Flip 03-34/1, Flip 12-22, Flip 00-21, Flip 97-126, Flip 98-30. Based on the results of the study, highly productive samples of chickpeas with a seed weight from plants from 15 to 16g were identified - these are (k151-16.2g; k118 - 15.2g; k2814 -15.4g; Flip98-73 -16.4g; k2956 Obraztsov Chiflik 1 - 15.2g; Flip 02-70- 16.0g).
