Abstract

In this study, the relationships between grain yield and yield characteristics were analyzed by running correlation and linear regression analyses. In the study, the herbal properties of 18 registered chickpea varieties and 3 local chickpea lines were used. The trials were continued for two years in two locations in the transitional zone of the Antalya-Korkuteli-Ulucak village and the coastal conditions of Antalya Aksu in the western Mediterranean region. According to the results of correlation and regression analysis, significant correlations were found between the yield and the number of the days to 50% emergence (r = -0.6707 and p&lt;0.01), the number of days to 50% flowering (r = -0.6446 and p&lt;0.01), number of days to maturity (r = -0.7303 and p&lt;0.01), plant height (r = 0.4304 and p&lt;0.01), first pod height (r = 0.5990 and p&lt;0.01), number of pods per plant (r = -0.1681 and p&lt;0.05) and the number of seeds per pod (r = 0.2696 and p&lt;0.01). Although the data obtained as a result of the regression analysis did not exactly match the data determined, it was determined that close or average values could be reached, which may be beneficial for breeding activities.

Highlights

According to the results of correlation and regression analysis, significant correlations were found between the yield and the number of the days to 50% emergence (r = -0.6707 and p
Due to the narrowness of adaptation boundaries (Şehirali and Özgen, 1988; Singh and Bejiga, 1990; Bozoğlu and Gülümser, 2000; Sayılğan and Kocatürk, 2019), it is more appropriate to carry out breeding activities in the chickpea plant as sub-programs and regionally
It is known that earliness in maturity has increased and maturity periods are reduced due to the effects of phenological deviations resulting from global climate change, which has accelerated recently (Penuelas and Filella 2001; Walther et al, 2002; Craufurd and Wheeler, 2009; Visser et al, 2010; Sayılğan, 2016; Yavaş and Ünay, 2018; Gülser et al, 2019)

Summary

Introduction

Due to the narrowness of adaptation boundaries (Şehirali and Özgen, 1988; Singh and Bejiga, 1990; Bozoğlu and Gülümser, 2000; Sayılğan and Kocatürk, 2019), it is more appropriate to carry out breeding activities in the chickpea plant as sub-programs and regionally. In genotype choices with high adaptability in regional breeding studies, the yield is generally emphasized as the final output, and in the existing ecological conditions, the varieties with the highest yield and high stability are preferred. The genetic structure of the plant, the effect of the environment and the effects of cultural processes separately or together have an impact on the yield These effects make themselves felt in different parts of the plant during the plant development period and directly or indirectly influence the yield. This situation brings about a variety of disadvantages, it provides future-oriented inferences based on predictable results that facilitate breeding. The phenological and morphological features that are thought to be effective on especially the yield are emphasized in these studies
