Determining relationships among yield and some yield components using path coefficient analysis in chickpea ( Cicer arietinum L.)

Abstract

Chickpea is an important source of protein and has a major role at human nutrition and it is essential to know the relationships between yield and its components in chickpea breeding programs. In this study, five chickpea lines provided from the chickpea breeding program of Field Crops Department, Faculty of Agriculture, Ankara University were used. In the examined characteristics, positive and significant relationships were found statistically between the number of seeds pod −1 and the number of pods plant −1, between the number of seeds plant −1 and the number of pods plant −1 and the number of seeds pod −1, between seed yield plant −1 and the number of pods plant −1, the number of seeds pod −1, the number of seeds plant −1; between the number of seeds pod −1 and seed yield unit −1 area; between the number of seeds plant −1 and seed yield unit −1 area. Negative and significant relationships were determined statistically between the number of pods plant −1 and 100 seed weight, between the number of seeds pod −1 and 100 seed weight, between the number of seeds plant −1 and 100 seed weight, between seed yield unit −1 area and 100 seed weight. The total determining coefficient linking seed yield plant −1 and seed yield unit −1 area are 0.773 (77.3%) and 0.488 (48.8%) respectively in the model which were used in our research. And also total determining coefficient related to 100 seed weight was 0.896 (89.6%) in the same model.
