“…In terms of growth pattern, leaf output and nutritional properties, the majority of triploid mulberry plants outperform diploids. Due to their sterility and inability to set seeds, desired features of triploid mulberries might be preserved by clonal multiplication without any loss of leaf production potential (Vijayan et al, 2022) [31] . Moreover, C4-like photosynthetic 'trait' system, improved water, nitrogen and radiation usage efficiency and better resistance to high temperature and drought conditions were physiological features seen in mulberry germplasm.…”

Mulberry is an important crop for the sericulture sector because they are the main source of nutrition for silkworms. Sericulture is the practice of raising silkworms to produce silk, which is a valuable and opulent textile in many industries. Mulberry is the primary food source for silkworms, hence the availability and quality of mulberry are crucial to the sericulture industry. Therefore, development of improved varieties is essential for enhancing silk production. Attempts were made to develop high yielding mulberry varieties with vigorous vegetative growth and early sprouting suitable for tropical agroclimatic regions through controlled pollination. The importance of developing a high-yielding variety with early sprouting is emphasized, as it can lead to increased silk production with improved profitability to farmers. The review also describes methods of controlled pollination, which are used to produce hybrid seeds with desired traits. The various factors that influence the success of controlled pollination, including timing, temperature, humidity, and nutrition, are discussed. Finally, the review summarizes the research on the development of high-yielding mulberry varieties with vigorous vegetative growth and early sprouting. Overall, the information provides valuable insights into the development of improved mulberry varieties for tropical regions and highlights the potential for increased silk production and profitability to farmers.

“…In the last few decades, genetic relationship analysis of mulberry is an important component of crop improvement programs and molecular markers are the most popular to understand the diversity between Morus species [24,25]. Primarily, Xiang et al [26] applied the Random amplified polymorphic DNA (RAPD) technique to illustrate variation among different species of Morus.…”

“…Later Inter-Simple Sequence Repeats (ISSR) work has been reported on the genetic diversity analysis amongst the mulberry plants grown in India [24,27]. Additionally, several restrictions limit the estimation of the genetic diversity of mulberry as highlighted by earlier reports like-(a) lack of sufficient molecular markers in mulberry [28]; and (b) lack of codominant markers to construct the genetic map, which is considered to be a major constraint towards marker-assisted breeding for targeted trait improvement [25,29]. As mulberry has a highly cross-pollinated heterozygous genome, Simple Sequence Repeats (SSRs) are the most appropriate DNA markers to use for analyzing the genetic diversity of mulberries [28, 30-32].…”

Elucidation of genome size (GS), genetic and phenotypic variation is the fundamental aspect of crop improvement programs. Mulberry is a cross-pollinated, highly heterozygous tree eudicot, and comprised of huge ploidy variation with great adaptability across the world. However, because of inadequate information on GS, ploidy-associated traits, as well as the correlation between genetic and phenotypic variation hinder the further improvement of mulberry. In this present research, a core set of 157 germplasm accessions belonging to eight accepted species of Morus including promising functional varieties were chosen to represent the genetic spectrum from the whole germplasm collection. To estimate the GS, accessions were subjected to flow cytometry (FCM) analysis and the result suggested that four different ploidies (2n = 2x, 3x, 4x, and 6x) with GS ranging from 0.72±0.005pg (S-30) to 2.89±0.015pg (M. serrata), accounting~4.01 fold difference. The predicted polyploidy was further confirmed with metaphase chromosome count. In addition, the genetic variation was estimated by selecting a representative morphologically, diverse population of 82 accessions comprised of all ploidy variations using simple sequence repeats (SSR). The estimated average Polymorphism Information Content (PIC) and expected heterozygosity showed high levels of genetic diversity. Additionally, three populations were identified by the model-based population structure (k = 3) with a moderate level of correlation between the populations and different species of mulberry, which imply the effect of genetic variation instead of ploidy on trait plasticity that could be a consequence of the high level of heterozygosity imposed by natural cross-pollination. Further, the correlation between ploidies, especially diploid and triploid with selected phenotypic traits was identified, however, consistency could not be defined with higher ploidy levels (>3x). Moreover, incite gained here can serve as a platform for future omics approaches to the improvement of mulberry traits.

Genome size, genetic diversity, and phenotypic vitiation were estimated to develop a model-based population structure and identify ploidy-associated traits of a wide collection of cross-pollinated, highly heterozygous tree species of Morus.
