Rezumat

This report presents the results of studies of 10 genotypes of chickpea (generation F9: 10) from the intraspecific hybrid combination ♀MDI 02432 × ♂MDI 02419 for yield, biotic stress and characteristics of some morph biological traits. The material under study was distributed randomly in 3 replicates, each 2m2, as check was Botna variety. The season (2020) was unfavorable: early drought and favorable conditions for the development of pathogens Ascochyta rabiei L. and Fusarium oxysporum f.sp.ciceris. As the drought was foreseen, the seeding rate was increased. Yield due to unfavorable conditions was low and ranged from 56.7 g / m2 (C11) to 121.4 g / m2 (C6), cv. Botna -112.4 g / m2. The C6 genotype is followed by C4a and C5 with an average yield of 106.3 and 104.4 g / m2, respectively. A significant effect on yield was influenced by the reaction of genotypes to resistance to F. oxysporum. Thus, a high correlation was established (r = 0.796) between yield and the number of fruiting plants (not damaged by F. oxysporum). As a result: genotypes C6, C5 and C4a - resistant, C3 and C8- moderately resistant, C4b - tolerant and C11, C13, C14a and C14b moderately susceptible. In relation to the 2nd pathogen (A. rabiei), all genotypes were resistant with the exception the C13 (moderately resistant). Seed type: intermediate type desi-gulabi predominated (slight wrinkling with peashaped form). The following genotypes belong to this group: C3, C4a, C5, C6, C11 and C13. The remaining 4 genotypes (C4b, C8, C14a and C14b) are gulabi. Seed pigmentation, all desi-gulabi were characterized by dark cherry skin pigmentation, C4b (orange), C8 and C14a (brown), and C14b (dark beige). Botna variety: desi type and brown pigmentation. Plant height (mean value) varied from 46.9 cm (C3) to 51.5 cm (C11), Botna cultivar (39.1 cm). The most productive and resistant to F.oxysporum genotypes C6, C5 and C4a had values of 47.7 cm, 48.1 cm and 48.5 cm, respectively. The weight of 100 seeds (mean) varied from 28.48 g (C4b) to 35.12 g (C6), the latter exceeding the check by 22.1% (Botna 28.24 g). In 8 genotypes, the trait had certain variability, the highest in the C4b genotype with mean values (repetition) of 26.16g, 28.57 and 30.7g. Genotype C6, the mean values of which are 34.4g, 36.2g, and 34.7g, and were noted with the greatest variability within replicates (V = 3.8 - 4.8), cv. Botna (V = 3.0). Genotypes C3, C4a, C8, C14a, and C14b are evenness within replicates (V≤3.2), but some variability between replicates. Genotypes C5 and C11 are evenness both within and between replicates. Ripening breeding material on August 13-14, a few days later than cv. Botna (August 10).
