Genetic estimates and path coefficient analysis in chickpea (Cicer arietinum L.) under normal and late sown environments

Abstract

The research was carried out to determine selection criteria using correlation and path coefficient analysis in 25 chickpea (Cicer arietinum L.) genotypes under two different environments during rabi 2008-09 at Palampur location. The genotypes showed highly significant differences for all the characters studied in both environments. Environment I (normal sowing) exhibited its excellent potential for the traits viz., seed yield per plant, biological yield per plant, pods per plant, primary branches per plant, days to 50% flowering, days to maturity and plant height, whereas environment II (late sowing) exhibited it for harvest index, per cent crude protein and 100-seed weight. High heritability coupled with high genetic advance was observed for seed yield per plant, pods per plant and 100-seed weight in environment I. Seed yield per plant was positively and significantly correlated with pods per plant (E1=0.767 and E2=0.647), harvest index (E1=0.767 and E2=0.745), biological yield per plant (E1=0.612 and E2=0.537) and primary branches per plant (E1=0.422 and E2=0.515) in both the environments. Path coefficient analysis revealed the high direct effect of biological yield and harvest index towards seed yield per plant, whereas primary branches per plant and pods per plant showed negligible direct effect, but their indirect contribution for it through biological yield and harvest index was high. The present study suggests that selection for high seed yield should be based on selecting high biological yield, pod per plant, high test weight and primary branches per plants in chickpea.

Response of chickpea genotypes to drought stress under normal and late sown conditions

“…Reduction in maturity day was high in some of the genotypes while others showed less reduction. Similar results were also reported earlier by Hussain et al (2015), Meena and Kumar (2015), Dehal et al (2016). Eleven genotypes viz., Çakır, FLIP 03-42 C, ILC 8617, ICC 4567, ENA 8-2, ICC 1205, İzmir, FLIP 03-21 C, F4 09 -16105-31-2, EN 952 and ENA 144-10 were early maturing types.…”

“…These results revealed wide range of genetic variability and scope of selection for these traits. Similar findings were reported by Meena et al (2014), Dehal et al (2016). All the measured traits significantly decreased under stress condition compared to non-stress one (Table 2).…”

“…The reduction in plant height in chickpea due to stress was reported earlier by Hussain et al (2015), Dehal et al (2016). The vegetative phase governs the overall phenotypic expression of the plant and plays an important role in the realization of final grain yield.…”

“…The generative growth and sink capacity relates with final produce of the plant which get reduced under soil moisture deficit condition. Dehal et al (2016) in the field experiment on chickpea genotypes under soil moisture deficit reported that, under water stressed condition; there was decrease in seed yield (33.54 %) as compared to irrigated conditions. Similarly, Meena and Kumar (2015), Hussain et al (2015), Dehal et al (2016) findings revealed the ability of genotypes to produce more seed yield in drought stress condition.…”

Effects of seeding date and seeding rate on yield, proximate composition and total tannins content of two Kabuli chickpea cultivars

“…Higher CP content in delayed sowings was also reported for chickpea by Singh et al (1990), Kaya et al (2010) and Dehal et al (2016). The effect of spring or autumn planting on protein content is well known in wheat, in which a delay in sowing date was asso- ciated with a decrease in mean grain weight along with an increased per-grain total nitrogen content, thus leading to an overall increase in protein percentage (Motzo et al, 2007).…”
