CHARACTERIZATION IN F1 GENERATION OF KABULI, DESI AND WILD CICER GENOTYPES FOR PLANT TRAITS

Abstract

It is important to understand the magnitude of the changes in variation created by the crossbreeding of cultivated chickpea varieties with a narrow genetic base, desi and kabuli types, and C. reticulatum and C. echinospermum, which are closely related species to cultivated chickpeas. The study was conducted at Dicle University, Agriculture of Faculty, Diyarbakir, Turkiye, in 2023. The experiment laid out in randomized complete block design with three replications. Desi × kabuli, kabuli × kabuli and kabuli × wild Cicer F1 crosses and their parents were evaluated to estimate the heterosis, heterobeltiosis, potence ratios and heritability for the days to first flowering, leave traits, plant height, number of nodes per plant, flower and foliage color, anthocyanin pigmentation and plant growth habit. The differences among genotypes were significant for all these traits. The magnitude of heterosis was differed between traits and crosses. For days to first flowering, heterosis for early crosses ranged from -2.56% to -7.13%. Azkan (lately) × C. reticulatum (medium early) (-14.06%) had the highest negative heterobeltiosis for days to first flowering. The high heritability was estimated for days to first flowering, days from emergence to podded, and days from flowering to podded. The estimated values of potence ratios in most F1 crosses were negative for the number of days to first flowering. In crosses between the white-flowered parents Azkan, Gokce, ILC 533, ILC 1929 and ILC 482 and the pink-flowered parents JG 11, ICCV 96029, ICCV 03107, Black and wild Cicer species the F1s were pink. When the white-flowered the kabuli parents to the pink-flowered the desi parents were crossed, the F1s showed the anthocyanin pigmentation on various plant parts. © (2023), (Serbian Genetics Society).
