“…The number of leaves produced varied from 21.8 to 24.7 with a mean of 23.3; petiole width variers from 5.3 to 19.8 with a mean of 9.0, petiole depth varied from 4.0 to 9.6 with a mean of 6.8, the girth of genotypes varied from 199.7 to 378.0 cm with a mean of 284.7 cm. Sex ratio, number of leaves, petiole width, and petiole depth results are congruent with Balakrishna et al (2018). The height of the palm varied from 123.0 to 522.3, with a mean of 299.7 cm.…”

“…Based on correlation and path coefficient analysis (Balakrishna et al, 2018), major emphasis should be placed on the selection process with the high number of bunches, Average bunch weight (ABW), total dry matter (TDM), and bunch index (BI) for better genotype with superior oil quality and realising higher FFB yield. Selection based on bunch yield alone will not be sufficient to get the best hybrids, looking for plants with high bunch index and other bunch traits may produce superior yield and uniform palms (Corley, 1976).…”

Oil palm is a vegetable oil yielding, cross-pollinated crop belonging Arecaceae family, having a high potential for increasing oil yield to fulfil the requirement of edible oil in the country. Evaluation of oil palm germplasm was carried out at ICAR-IIOPR, Pedavegi, in 73 genotypes. A correlation study reported that the height of the palm was positively correlated with height increment, rachis length, number of a leaflet, bunch number, and FFB yield. In contrast, the girth of the palm was negatively correlated with the bunch index. Two Dura genotypes viz., IC0610049-40 and IC0610051-71 with high FFB yield (276.2 and 234.6 kg palm-1 year-1, respectively) with more number of bunches palm-1 year-1 (15.3 and 16.7, respectively) and high oil to bunch ratio (20.9% for both) and one Tenera genotype IC0610049-39 with 202.5 kg FFB with 11.7 bunches palm-1 year-1 and 23.0 per cent oil to bunch ratio were selected. One low height increment Dura palm IC0610045-3 with 19.56 cm year-1 and these genotypes can be used in the future breeding program for developing mother palms for production of Tenera hybrid.

“…Leaf number, seedling height, and girth, as well as seedling dry weight, were found to be strongly and positively correlated [21]. Balakrishna et al [22] discovered a positive correlation between leaf area and bunch yield in oil palm. Marjuni et al [23] discovered a correlation between palm height (HT) and the quantity of fresh fruit bunches, as well as the average bunch weight.…”

Oil palm crops are the most important determinant of the agricultural economy within the segment of oilseed crops. Oil palm growing in their natural habitats are often challenged simultaneously by multiple stress factors, both abiotic and biotic that limit crop productivity and are major constraints to meeting global food demands. The stress-tolerant oil palm crops that mitigate the effects of abiotic stresses on crop productivity are crucially needed to sustain agricultural production. Basal stem rot threatens the development of the industry, and the key to solving the problem is to breed new oil palm varieties resistant to adversity. This has created a need for genetic improvement which involves evaluation of germplasm, pest and disease resistance, earliness and shattering resistance, quality of oil, varieties for different climatic conditions, etc. In recent years, insights into physiology, molecular biology, and genetics have significantly enhanced our understanding of oil palm response towards such stimuli as well as the reason for varietal diversity in tolerance. In this review, we explore the research progress, existing problems, and prospects of oil palm stress resistance-based physiological mechanisms of stress tolerance as well as the genes and metabolic pathways that regulate stress response.

“…It is indicated by the value of the coefficient of variance, which is below 20 percent (Table 2). Therefore, the selection program can only be achieved by utilizing valid information about the correlation and the variance in the population [11] In addition, the effectiveness of breeding programs can be developed through the genetic variance of the available plant populations [12].…”

A challenge still being faced at the coconut farmers’ level is the low productivity, which is only at an average of 1.2 tons of copra per hectare per year. Apart from being caused by old plant age, it is also caused by low-quality seeds. The types of superior coconut that are currently available are still limited, especially the tidal-specific varieties. The research was conducted in the Village of Tanjung Solok, East Tanjung Jabung Regency, Jambi Province, Indonesia, from 2015 to 2018, using an observational survey, which was aimed to find promising lines of coconut that suitable for the tidal areas. The observed characters include vegetative, generative, and fruit components. The analysis of the coefficient variance was carried out to determine the level of variance and production potential of the Zabak Tall coconut. Meanwhile, the yield stability was analyzed by observing the linearity of the production characters for three years. The results showed that the productivity of Zabak Tall is at about 3.09 tons of copra per hectare per year, which is stable for three years of observation and even tends to increase due to selection activities.
