Quality seed production scenario of Egyptian clover ( Trifolium alexandrinum) in India: A 24-year retrospective analysis. Heliyon 2024; 10:e35735. [PMID: 39170533 PMCID: PMC11336856 DOI: 10.1016/j.heliyon.2024.e35735] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Revised: 07/16/2024] [Accepted: 08/02/2024] [Indexed: 08/23/2024] Open
Abstract
Egyptian clover/Berseem (Trifolium alexandrinum L.) is the most popular winter leguminous multi-cut fodder crop widely cultivated in the northwest and central parts of India. Quality seed significantly impacts farm productivity, farmers' profitability, and socioeconomic welfare. Foundation and certified seeds enable high-quality seed production, making breeder seed (BS) the most important link in the seed supply chain. In India, berseem BS indent had increased from 1998 - 99 to 2012-13; afterwards, it followed a constant but decreasing trend. Of the 27 notified cultivars, 24 came into the seed supply chain between 1998-1999 and 2021-2022, indicating high varietal availability to stakeholders. The study examines the potential causes of the national decline in BS indent and production and the differences in these figures over time. The highest BS indent was received for the variety JB-1 (276.1 q), followed by BL-10 (205.1 q), Mescavi (165.6 q) and Wardan (153.7 q) from 1998 - 99 to 2021-22. The varietal replacement rate (VRR) is high, 43.30 %, for the varieties that have reached the age of five or less in the recent three years (2019-20 to 2021-22). Additionally, it has been calculated that if the seed chain operates at 100 % efficiency, the BS generated (48.1q) in 2021-22 can cover an area of almost 0.12 million hectares in 2024-25. The study offers an in-depth overview of berseem BS indent and production, an analysis of the difficulties encountered in BS production, and future directions for expanding variety and producing excess BS in the nation.

Abstract
The genus Trifolium is one of the largest genera of the legume family Fabaceae with ca. 255 species. The genus is divided into eight sections; the section Trifolium is a major section of the genus, comprising 73 species mainly distributed in the Mediterranean region. We used nuclear ribosomal DNA internal transcribed spacer (ITS) and morphological variation to reconsider the delimitation and phylogenetic relationships of species in the section Trifolium with reference to chromosomal variations. Bayesian analysis of ITS data delimited the species as three clades based on the analysis of ITS sequence and informative indels in combination with morphological variation. The phylogeny of the species by different analyses methods does not support their current delimitation in 17 subsections. The basic chromosome number x = 8 is the number for the genus Trifolium, from which x = 7, 6 and 5 were derived through successive aneuploidy events. With reference to the distribution of these numbers in the species of the section Trifolium, species in clade III and clade II are more evolved than species in clade I.

[PMID: 33717683 PMCID: PMC7936568 DOI: 10.7717/peerj.10874] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Accepted: 01/11/2021] [Indexed: 12/02/2022] Open
Abstract
Background The genus Trifolium is characterized by typical trifoliolate leaves. Alterations in leaf formats from trifoliolate to multifoliolate, i.e., individual plants bearing trifoliolate, quadrifoliolate, pentafoliolate or more leaflets, were previously reported among many species of the genus. The study is an attempt to develop pure pentafoliolate plants of T. alexandrinum and to understand its genetic control. Methods The experimental material consisted of two populations of T. alexandrinum with multifoliolate leaf expression, i.e.,interspecific hybrid progenies of T. alexandrinum with T. apertum, and T. alexandrinum genotype Penta-1. Penetrance of the multifoliolate trait was observed among multifoliolate and trifoliolate plant progenies. In vitro culture and regeneration of plantlets from the axillary buds from different plant sources was also attempted. Results The inheritance among a large number of plant progenies together with in vitro micro-propagation results did not establish a definite pattern. The multifoliolate leaf formation was of chimeric nature, i.e., more than one leaf format appearing on individual branches. Reversal to normal trifoliolate from multifoliolate was also quite common. Penetrance and expression of multifoliolate leaf formation was higher among the plants raised from multifoliolate plants. Multifoliolate and pure pentafoliolate plants were observed in the progenies of pure trifoliolate plants and vice-versa. There was an apparent increase in the pentafoliolate leaf formation frequency over the years due to targeted selection. A few progenies of the complete pentafoliolate plants in the first year were true breeding in the second year. Frequency of plantlets with multifoliolate leaf formation was also higher in in vitro axillary bud multiplication when the explant bud was excised from the multifoliolate leaf node. Conclusion Number of leaflets being a discrete variable, occurrence of multifoliolate leaves on individual branches, reversal of leaf formats on branches and developing true breeding pentafoliolates were the factors leading to a hypothesis beyond normal Mendelian inheritance. Transposable elements (TEs) involved in leaf development in combination with epigenetics were probably responsible for alterations in the expression of leaflet number. Putative TE’s movement owing to chromosomal rearrangements possibly resulted in homozygous pentafoliolate trait with evolutionary significance. The hypothesis provides a new insight into understanding the genetic control of this trait in T. alexandrinum and may also be useful in other Trifolium species where such observations are reported.

Abstract
Trifolium alexandrinum (Egyptian clover) is a widely cultivated winter annual fodder. Present work deals with inheritance of the seed coat colour in segregating progenies of the interspecific cross between T. alexandrinum and T. apertum. Although, both the parent species possessed yellow seed coat, the F1 seeds were black coloured in the reciprocal cross (T. apertum × T. alexandrinum). Seeds borne on individual F2 plants and the advancing generations segregated in yellow and black seed coat colour, which confirmed xenia effect. F2 seeds collected from individual F1 plants exhibited nine black and seven yellow segregation ratio. The segregation of the seed coat colour recorded from F3 to F5 generations revealed that yellow seed coat was true breeding (i.e. non-segregating) in this interspecific cross (including the reciprocal crosses). However, the black seeded progenies were either true breeding or segregated in nine black: seven yellow ratio or three black: one yellow ratio suggesting a complementary gene interaction or duplicate recessive epistasis. It indicated that the seed coat colour is controlled by complementary gene interaction along with xenia effect in interspecific crosses between T. alexandrinum and T. apertum. Occurrence of the complementary genes across the species could suggest T. apertum to be the progenitor of T. alexandrinum. Inheritance of seed coat colour in reference to its importance in Egyptian clover breeding is also discussed.
