“…Seed yield was significantly reduced in the late seeded population in all the locations as compared to the normal seeded population except Lucky Lake, 2020 which could be because of less stressed conditions while the late seeded population in Lucky Lake. Similar to our findings, previous studies have also shown reduced yield under late seeded populations (Machado et al, 2006;McKenzie et al, 2006). The calculation of spearman's rank correlation coefficients between seed yields acquired under normal and late seeding and the stress tolerance indices for each year was done.…”

Genome-wide association analysis of stress tolerance indices in an interspecific population of chickpea

Chickpea is a cool season crop that is highly vulnerable to abiotic stresses such as heat and drought. High temperature during early flowering and pod development stages significantly reduces the crop yield. The wild relatives of chickpeas can be potential donors for the introgression of heat and drought tolerance into cultivated chickpeas for crop improvement. Initially, 600 interspecific lines were derived from crosses between two elite cultivars, CDC Leader (kabuli chickpea) and CDC Consul (desi chickpea), and 20 accessions of Cicer reticulatum. The F5 interspecific lines were tested for agronomic and seed quality traits including reaction to ascochyta blight disease under field conditions at two locations in 2018. A subset of 195 lines were selected based on resistance to ascochyta blight and acceptable seed quality. These lines were evaluated for their performance under suboptimal conditions at Lucky Lake (2019 and 2020) and Moose Jaw (2019), Saskatchewan, Canada, and Yuma, Arizona, United States (2019–2020). The lines were grown and evaluated at two seeding dates, normal (SD1) and late (SD2) seeding dates, at each location and year. The same lines were genotyped using Cicer60K Axiom® SNP chip. The population structure was determined based on 35,431 informative SNPs using fastStructure, and the interspecific lines were clustered at a k-value of 15. Significant marker-trait associations were identified for seed yield from SD1 and SD2 seeding dates, and stress tolerance indices (ATI, K1STI, MP, SSPI, and TOL) using phenotypic values both from individual locations and combined analyses based on BLUP values. SNP marker Ca2_34600347 was significantly associated with yield from both the seeding dates. This and other SNP markers identified in this study may be useful for marker-assisted introgression of abiotic stress tolerance in chickpea.

“…Previous studies have also used the same approach to understand the effect of stress on crop development and yield in canary seeds (Miller, 1999). Furthermore, it was observed that late seeding has a negative effect on chickpea yield (Machado et al, 2006;McKenzie et al, 2006).…”

“…Significantly maximum seed yield (21.97 q/ha) was recorded in plot having75 kg/ha seed rate, (Table 3) followed by 60 kg/ha and 90 kg/ha seed rate. Machado et al (2006) in his study observed that when seed rate was increased from 60 to 75 kg seed rate per hectare, the yield was also increased by 8%. The similar research was undertaken by Nawange et al (2016).The mean of different row spacing gave highest seed yield (22.67 q/ha ) when row spacing of 30 cm was kept, followed by row spacing of 40 cm and 20 cm, respectively.…”

Background: Chickpea is a cool season legume crop and is grown in several countries worldwide as a food source. Seed is the main edible part of the plant and is a rich source of protein, carbohydrates and minerals especially for the vegetarian population. The current study aimed to study the effect of seed rate and seed spacing on yield attributes of chickpea. Methods: The research was carried out at Research Farm, Department of Agriculture, Maharishi Markandeshwar University, Sadopur, Ambala during Rabi season in 2020-2021. The experiment was laid out in split plot design (SPD), with three replication and 9 treatments with two conditions i.e. three different seed rate (60, 75 and 90 kg/ha) and seed rate were design in main plot, where as in sub-plot three spacing (20, 30 and 40 cm) were tested. Result: The result revealed that seed rate of 75 kg/ha with row spacing of 30 cm in chickpea crop recorded maximum seed index (21.70 g), seed yield (23.26 q/ha), straw yield (26 q/ha), biological yield (49.16 q/ha) and harvest index (47%). The maximum number of pods per plant (107.63) and seeds per pod (2.13) were observed when the seed rate of 60 kg/ha and row spacing of 40 cm was used.

“…Chickpea varieties are classified into two types based on seed size, shape, and color. Varieties with small, angular, and tan to brown‐colored seeds are classified as desi types and those with large, ram‐head shaped, beige‐colored seeds are known as kabuli types (4,8).…”

“…Lack of moisture in stubble fields limited plant growth at high population. In eastern Oregon, optimum seeding rates for chickpea ranged from 3 to 5 seeds/feet 2 depending on chickpea variety (8). In southwestern Australia optimum plant density for desi chickpea ranged from 24 to 112 plants/m 2 and was dependent on yield potential of the site (6).…”

Chickpea (Cicer arietinum L.) has recently been introduced to the semiarid regions of South Dakota. Kabuli type varieties targeted for the high value salad bar market dominate production in the state. Very little is known about the response of chickpea varieties to changes in management practices such as planting dates and fertilizer and seeding rates. This study was conducted at two locations in 2005 to 2006 to determine the effect of seeding rate on chickpea yield and yield components. The study had two kabuli chickpea varieties each year and six seeding rates ranging from 10 to 60 viable seeds/m2. Increasing the seeding rate increased seed yield at the two locations in both years. Optimum seeding rate for maximizing seed yield ranged from 40.6 to 52.5 seeds/m2 depending on growing conditions. Harvest index was relatively constant at seeding rates above 20 seeds/m2. Chickpea plants compensated for low plant populations by producing more pods per plant although this was not enough to maintain high yield at low seeding rates in all environments. Seed weight decreased with increasing seeding rate suggesting that higher plant populations result in smaller seeds.
