Association of flowering time with phenological and productivity traits in chickpea

Abstract

Phenology is an important trait for the adaption of chickpea (Cicer arietinum L.) to various target environments. The aim of this study was to determine the effects of flowering time on other phenological traits and yield-related traits. F 2 and F 3 segregating populations derived from the crosses of four early-flowering lines (ICCV 96029, ICC 5810, BGD 132 and ICC 16641) with a late-flowering cultivar (CDC Frontier) were used. In all crosses, flowering time showed significant positive association with days to pod initiation, days to maturity, plant height and biomass and non-significant correlation with number of pods per plant, number of seeds per plant and grain yield per plant. Flowering time had a positive correlation with 100-seed weight in all crosses, with the exception of ICC 16641 9 CDC Frontier where the correlation was non-significant. Harvest index was negatively associated with flowering time. In most of the crosses, early-and late-maturing F 3 bulks showed significant differences with respect to biomass and harvest index, while for grain yield and 100-seed weight the differences were found to be non-significant. These results indicate that flowering time could be used as a reliable selection criterion in breeding for early-maturing chickpea and that a reduction in the duration of flowering time and maturity may not necessarily have a yield penalty in these genetic backgrounds.

Genetic Diversity and Environmental Influence on Growth and Yield Parameters of Bambara Groundnut

“…But we can conclude from the findings that the tall plants should attain maturity earlier than the short plants because the tall plants flower early, which means that they enter the vegetative stage earlier than the short plants. Similar correlations have been reported in Chickpea where the tall plants flower earlier than the short plants (Mallikarjuna et al, 2019). Likewise, accessions that have a higher number of petioles and leaves, flower late, and have poor germination.…”

Integrative Analyses of Transcriptomes and Metabolomes Reveal Associated Genes and Metabolites with Flowering Regulation in Common Vetch (Vicia sativa L.)

“…Switchgrass is a perennial C 4 grass that is undergoing development as a dedicated biomass feedstock for conversion to bioenergy, and its biomass yield is strongly influenced by delayed flowering, averaging +0.03 to 0.13 Mg ha −1 for each day’s delay in the anthesis date [ 52 ]. A previous study reported that the flowering time shows a significant positive association with days to pod initiation, days to maturity, plant height, and the biomass of chickpea [ 53 ], and similar results appear in the present study. Three years of field trials have shown that the growth period and the dry weight of early-flowering accession (Lan3) are significantly less than those of late-flowering accession (503) ( Figure 1 ), indicating that the flowering time can affect the yield of V. sativa .…”

Linking phenology, harvest index and genetics to improve chickpea grain yield

“…Early reproduction has long been recognised as a desirable trait to achieve higher or more stable yields in chickpea in a range of environments (Berger et al ., 2004; Mallikarjuna et al ., 2019; Nunavath et al ., 2020). Chickpea grain yield is closely related to grain number, which is in turn proportional to the duration and growth rate during this critical period (Lake and Sadras, 2016; Sadras et al ., 2015).…”
