“…The double-podded ("s" allele) in the cultivated chickpea was governed by a single recessive gene as all F 1 progeny were singlepodded and the F 2 populations segregated in a ratio of 3 (singlepodded): 1 (double-podded) ( Table 1), suggesting that these results were in agreement with previous reports (Rao et al, 1980;Singh & van Rheenen, 1994;Kumar, Srivastava et al, 2000;Gaur & Gour, 2002;Yasar et al, 2014). Segregation ratios for single-podded vs.…”

Gene effects of Cicer reticulatum on qualitative and quantitative traits in the cultivated chickpea

et al. 2017

The gene effects of Cicer reticulatum on both double‐podding as qualitative traits and yield criteria as quantitative traits in interspecific hybridization with cultivated chickpea (Cicer arietinum) have not yet been elucidated, despite the easy acquisition of hybrid progeny between two species. This study sought to answer three questions concerning qualitative and quantitative traits in reciprocal crosses between C. arietinum and C. reticulatum. (i) Is there a similarity in the gene effects of flower colour, pigmentation and double‐podded traits in reciprocal interspecific crosses? (ii) What are the expressivity and penetrance of the double‐podded trait in interspecific crosses? (iii) Which heterosis predicts the occurrence and the extent of transgressive variation? The materials for this study were F1, F2 and F3 progeny derived from a reciprocal cross between C. arietinum and C. reticulatum. As qualitative traits, purple flower colour, pigmentation and single‐podded traits in C. reticulatum were governed by a dominant single gene. Purple flower colour and pigmentation were detected to be linked traits as all progeny had the same phenotypes. As quantitative traits, yield criteria in progeny which were double‐podded had higher values than the single‐podded counterparts. Expressivity and penetrance of the double‐podding trait were superior in progeny derived from C. reticulatum × C. arietinum. The results showed that fruitful heterosis was more useful than residual heterosis in F3 as residual heterosis was mostly negative and fruitful heterosis was suggested in self‐pollinated species such as chickpea that lacks inbreeding depression. Interspecific transgression was significant with respect to chickpea improvement because it represented a potential source of novel genetic variation.

“…Furthermore, the genotype PMF-1 has also expressed MF even at the Sehore location (Madhya Pradesh, India) during 2018-2019. Similar results were reported in other pulses like garden pea (Devi et al, 2018;Sanwal et al, 2016) and chickpea (Gaur & Gour, 2002).…”

“…Thus, the average yield for India is low (736 kg ha −1 ), even lower than the world average (1,153 kg ha −1 ) (FAOSTAT, 2019;Saxena, 2009). For centuries, inflorescence morphology of various legumes such as garden pea (Pisum sativum L.), chickpea (Cicer arietinum L.), and lentils have attracted the attention of various researchers (Devi et al, 2018;Gaur & Gour, 2002;Sandhu & Singh, 2007). Furthermore, the genetic regulation of flowering patterns in any crop is of immense practical importance for the breeders aiming to develop high-yielding cultivars (Sinjushin & Liberzon, 2016).…”

“…To date, there is no published report on cultivated lentil genotype stably forming five FPP, but a few wild genotypes-L. tomentosus Ladizinsky, L. ervoides (Brign) Granade, and L. orientalis (Boiss) Ponert (Sharma, 2009)-are known to express MF (multi-flowering) node to the tune of five FPP. Technically, a plant is considered MF when there is expression of three or more flowers at one or multiple flowering nodes (Benlloch et al, 2015;Devi et al, 2018;Gaur & Gour, 2002). Multi-flowering racemes have been reported for a few and not for all the flowering nodes in pulses like P. sativum (up to five FPP) (Devi et al, 2018) and chickpea (up to nine FPP) (Gaur & Gour, 2002), where varied mechanisms for flower number regulation operate (Gaur & Gour, 2002;Sinjushin & Liberzon, 2016;Talukdar, 2013).…”

Identification and characterization of novel penta‐podded genotypes in the cultivated lentil

et al. 2020

Our study reports the identification of two novel multi-flowering (MF) genotypes, PMF-1 and PMF-2, in cultivated lentil (Lens culinaris Medik.), stably forming up to five flowers per peduncle (FPP) on I2 nodes at multiple flowering nodes (beyond the ninth node). These genotypes were identified from the ICARDA (International Centre for Agricultural Research in the Dry Areas) nursery received from Lebanon. Stable MF was observed under open field conditions at IARI (the Indian Agricultural Research Institute), New Delhi, India, during the year 2017-2018 and 2018-2019, and also in the partially controlled glasshouse conditions. In addition, we identified two more stable genotypes, namely, PMF-3 and PMF-4, producing four flowers and a genotype, ILL7663, producing only one to two flowers at multiple flowering nodes under normal growing conditions. It is speculated that the expression of the MF trait is the result of interaction between specific genetic loci with the environmental conditions during the bud formation stage in the identified lines. The possibility of the presence of various genes known in other crops like pea (Pisum sativum L.) and chickpea (Cicer arietinum L.), along with various environmental factors regulating the MF expression, is also worked out for lentil. Further, these novel resources can be used for genetic studies aimed to identify the locus regulating the MF trait in lentil.

“…All annual legumes with high-yielding potential have compound inflorescences arranged in racemes, such as soybean (Hartung et al, 1981), common bean (Teixeira et al, 1999;Kelly, 2001), and chickpea (Cicer arietinum L.) (Gaur & Gour, 2002). However, cowpea cultivars released in the Brazilian market have simple inflorescences, with no exception, although there are records of this species having compound inflorescences worldwide (Araújo et al, 1981;Fawole & Afolabe, 1983;Sen & Bowal, 1961) -a cultivar with this trait, for example, was released in Nigeria (Fawole et al, 1985).…”

The objective of this work was to obtain cowpea (Vigna unguiculata) progenies with compound inflorescences, short peduncles, early cycle, good plant architecture, and high-yielding potential. The initial genetic material consisted of 453 F2:3 progenies, selected from ten crosses and evaluated using Federer’s augmented block design, with two controls. Of these, 60 progenies from the F4:5 and F4:6 generations were selected and assessed in two consecutive experiments, both in a 8x8 lattice design with four controls and four replicates. Early selection was efficient at fixing the evaluated traits. A wide genetic variability was detected among and within progenies. The estimated and obtained heritability and genetic gains in the F4:5 and F4:6 progenies indicate the possibility of selection of early progenies with short peduncles, compound inflorescences, and productivity similar to or greater than that of the commercial cultivars used as controls.
