“…These results were in line with the report of Anithakumari et al (2012). Batugal (1999) reported that the majority of coconut plantations in Indonesia belong to smallholders (98.7%), while the rest belong to private and state-owned enterprises. A look into the number of seedlings per homestead indicated that 37.14 percent do not have any seedlings, 28.57 percent had 1 to 10 numbers, 8.57 percent had 11 to 20, 14.28 percent had 21 to 30 and 11.42 percent had 31 to 50.…”

Three Grama Panchayats in Kerala's Alappuzha district undertook community-level participatory action research in 2019–2021. A total of 90 coconut farmers participated in the adoption of ICAR-CPCRI technology to produce West Coast Tall (WCT) coconut seedlings that are resistant/tolerant to the root (wilt) disease at the community level. Partners included extension agents, coconut producers' societies (CPS) and clusters, women self-help groups (WSHGs), and agricultural labor organizations. The characteristics of technologies that are suggested for adoption in root (wilt) disease-aﬀected tracts, such as the scientific management of young coconut trees and the production of high-quality seedlings through community nurseries, challenge the idea of adoption. There are a lot of variances in the homestead gardens' marginal holdings, including expertise, the use of technology, and access to advisory services. Government agencies provided the majority of the seedlings and extension advisory services, emphasizing the necessity for FPO-based or private extension in the coconut growing industry. The coconut farmers' understanding has significantly improved as a result of the participatory interventions for managing seedlings. The participatory demonstration and community farm school (CFS) strategy is discussed in the paper as a way for homesteads to manage juvenile coconuts while integrating new ideas and fostering cross and reciprocal learning. Refining the current extension approach requires integrating new knowledge about the characteristics of seedling growth, future economic performance, and social evaluation of choices of technological, individual, and skill-oriented interventions in risk-prone areas with debilitating root (wilt) disease.

The genetic diversity of agro-morphogenic traits in 14 genotypes of soybean (Glycine max L. Merr.) were studied in an experiment using a Complete randomizes Design (CRD). Each trait's analysis of variance revealed a substantial difference between genotypes. Multivariate analysis based on thirteen characters of fourteen soybean genotypes was divided into four clusters. The maximum contribution of traits towards diversity was observed by days to 50% flowering, plant height, number of main branches per plant and leaf area index. As a result, these traits could be emphasized during selection of parents for hybridization. The highest inter cluster distance was observed between cluster II and IV and the maximum intra cluster distance was found in cluster III. Considering group distance and other agro-morphogenic performance, genotypes G1 (BADC SV1) from cluster II, G10 (Asset-95) and G7 (BS-29) from cluster VII, G4 (GMOT-43) and G12 (BADC SV2) from cluster IV found potential for future hybridization program.

“…The coconut palm is an important cash crop which provides almost all the necessities of life; food, drink, oil, medicine, fiber, timber, thatch, mats, fuel, and domestic utensils (Batugal, 1999;Punchihewa, 1999). It is referred as the "tree of life" because of its immense importance as a subsistence crop and because of the multiplicity of uses.…”

The coconut palm is an important cash crop mostly in the subtropical countries which provides almost all the necessities oflife to the mankind. Genetic improvement for increased productivity is a prioritized research area of coconut palm. In vitro cloning ofelite palms via somatic embryogenesis seems to be a promising method due to its potential for massive propagation. Based on the Sri Lankan experience, this paper summarizes the notable achievements towards developing a reliable protocol for clonal propagation of coconut and also dihaploid plant production. The newel explant described by Coconut Research Institute Sri Lanka (CRISL), unfertilized ovaries dissected from immature inflorescences collected from-4 stage (inflorescence to be opened in 4 months time), is a somatic tissue which causes minimal damage to the mother palm while collecting. Limited number of female flowers in an inflorescence which limits large scale culturing could overcome by callus multiplication phase to produce higher number ofplants. Somatic embryogenesis and germination of somatic embryos was achieved by reduction of auxin concentration in the culture medium followed by an addition ofcytokinin. AINTEGUMENTA-LiKE (ANT-like) gene isolated from coconut genome which shows higher conserved domain sequence similarities with BABYBOOM gene will assist development of suitable molecular markers to assess the morphogenic potential of in vitro cultured coconut tissues and callus. Successful plant regeneration from cultured anthers was reported by culturing anthers at three weeks before splitting (3-WBS) inflorescence stage which contains late uninucleate microspores. Heat pretreatment of anthers for six days at 38°C induced androgenesis in coconut upon culturing in 2, 4-D and I-naphthyl acetic acid (NAA) added medium. Current clonal propagation protocol is efficient when responsive genotype is in use. Further improvement to current protocol will enable commercially viable protocol for coconut micropropagation.
