Abstract

Twenty chickpea genotypes including four varieties were evaluated for the existence of genetic variability and to know the interrelationship among yield traits under study during 2013-2014, at University of Agriculture, Faisalabad. The experiment was carried out in a randomized complete block (RCB) design with three replications. Data were recorded on number of days taken to flowering, number of primary branches plant-1, number of secondary branches plant -1, plant height, number of days taken to maturity, number of pods plant -1, numbers of seed pods-1, total plant weight, Number of grains plant-1, 100- seed weight and grain yield plant-1. The obtained data were analyzed for genetic variability parameters, correlation and path coefficient analysis. The height broad sense heritability estimates were obtained for 100-seed weight (0.977), plant height (0.971), total plant weight (0.971) and number of primary branches plant-1. Genetic advance was higher for plant height (9.054), total plant weight (9.054), number of pods plant-1 (6.414) and 100-seed weight (2.941). The phenotypic coefficient of variation (PCV) was invariably slightly higher than their corresponding genetic coefficient of variation (GCV) due to influence of environment on character expression. Heritability estimates were higher for all characters except number of days taken to maturity and number of grains per plant, which exhibited moderate heritability. Hundred seed weight, plant height, total plant weight and primary branches per plant would be the suitable selection criteria to accomplish better grain yield in chickpea.

Highlights

Chickpea (Cicer arietinum L.) commonly known as gram belongs to the family leguminosae is a major pulse crop that contributes about 12 % of the world pulse production (Khan et al, 2011)
Number of days to flowering at the time when at least 50% flowering was recorded for yield and its various yield contributing traits including, number of primary branches-1, number of secondary branches-1, plant height, number of days taken to maturity, number of pods plant -1, total numbers of grain per pods, total plant weight, Number of grains plant-1, 100- seed weight and grain yield plant1
The maximum grain yield was recorded in the variety PB2008, while the lowest yield was obtained from the genotype 3019

Summary

Introduction

Chickpea (Cicer arietinum L.) commonly known as gram belongs to the family leguminosae is a major pulse crop that contributes about 12 % of the world pulse production (Khan et al, 2011). For any breeding program the genetic variability play an important role as it provide opportunity to plant breeder for selection of high yielding genotypes.
