Genetic Variability and Diversity Analysis for Yield and its Associated Traits in Chickpea (Cicer arietinum L.)

Abstract

Chickpea (Cicer arietinum L.) is a leguminous self-pollinating crop belongs to family- Leguminosae (Fabaceae). The aim of a plant breeder is to identify or develop high yielding cultivars. In the present investigation, 83 genotypes grown during Rabi 2021-22 to investigate genetic variability, heritability and genetic advance, correlation, direct and indirect effects and genetic divergence (D2 analysis) among yield and its attributing traits. High GCV and PCV recorded for the numbers of pods per plant and biological yield indicating the presence of substantial amount of genetic variability in the experimenting material. High heritability coupled with high genetic advance was shown for seed yield per plant, hundred seed weight. Selection based on these traits may be proved worthwhile. Significant and positive correlation was documented for seed yield per plant with numbers of pods per plant and biological yield and path analysis signified that biological yield had the highest positive direct effect on seed yield per plant. The data obtained from the present investigation may be proved helpful in the selection of high yielding superior genotype (s) of chickpea.

Genetic Components and Variability Assessment for Grain Yield and Its Accrediting Traits in Maize (Zea mays L.)

“…Traits with high GCV values are more likely to respond positively to selection, as they are under strong genetic control. Conversely, traits with high PCV values may require more attention to environmental management and may have limited genetic potential for improvement [9][10][11][12][13][14][15][16].…”

“…Heritability estimates provide breeders with valuable insights into the proportion of phenotypic variation that can be attributed to genetic factors. By accurately estimating heritability, breeders can assess the potential for genetic improvement in specific traits [9][10][11][12]. This knowledge enables them to focus their efforts on traits with higher heritability, increasing the likelihood of success in genetic enhancement [12][13][14].…”

“…The diverse characteristics found within maize contribute to its extensive range of morphological, physiological, and agronomic traits, making it a valuable crop for plant breeders seeking to enhance its qualities [1]. Variability, heritability, and genetic advance are crucial concepts that aid breeders in comprehending the genetic diversity present in populations and assist in identifying and selecting the most promising individuals for further advancements [9][10][11][12][13]. Breeders utilize these parameters to identify individuals with desirable traits and make informed decisions regarding parental selection, hybridization, and advancement of breeding populations [14][15][16].…”

DUS-Based Morphological Profiling and Categorization of Chickpea (Cicer arietinum L.) Genotypes

“…India spearheads global chickpea cultivation, contributing a substantial 73.78% (10.943 million hectares) of the total global chickpea acreage and 73.45% (11.91 million metric tonnes) of production [13]. This underscores the pivotal role of India in sustaining global chickpea production and emphasizes the imperative to address challenges threatening its cultivation [14][15][16][17]. Despite its nutritional significance and adaptability, the cultivation of chickpea has encountered setbacks in recent times, marked by a decline in acreage and production [18][19][20][21][22].…”

Screening Chickpea Genotypes against Fusarium Wilt Disease under Controlled Conditions

“…Numerous biotic and abiotic factors contribute to the reduced productivity of chickpea [9][10][11][12][13][14][15][16][17][18]. A comprehensive survey conducted in 1995 across 55 countries revealed the presence of 172 pathogens causing various diseases in chickpea.…”
