“…The coefficient of genotypic variation (GCV) and the coefficient of phenotypic variation (PCV) are very useful in determining the amount of diversity that exists in the population and are the basis for variability criteria (Mustikarini et al 2019;Saidon et al 2020). All traits showed high PCV than GCV, similar to the results reported by Srivastava et al (2017); Tiruneh et al (2021), indicating that the variance observed for the traits was more influenced by the genetic factors and suitable environment support the expression of genetic (Kartahadimaja et al 2021). A notable difference in PCV and GCV values indicates a significant environmental influence positively on the traits.…”

Abstract. Marwan AP, Munandar A, Anwar A, Syarif A, Hayati PKD. 2022. Variability, heritability, and performance of 28 West Sumatran upland rice cultivars, Indonesia. Biodiversitas 23: 1058-1064. The abundance of genetic diversity, especially local upland rice cultivars, makes an excellent opportunity to obtain local cultivars with the desirable character. The study aimed to assess the genetic variability and heritability of agronomic traits among local upland rice cultivars from West Sumatra. In this study, 28 local upland cultivars from West Sumatra were subjected to the analysis of variance. The research was conducted from November 2020 to April 2021 at the Research Station of the Faculty of Agriculture, Andalas University, Padang. The evaluation was conducted using a Randomized Complete Block Design with three replicates. Results showed variation in each agronomic trait, ranging from intermediate to tall in plant height, short to moderate in panicle length, low to moderate in the number of tillers, days to flowering and days to maturity, and light to moderate in grain yield. Plant height, number of tillers, days to flowering, and days to maturity were traits with high to moderately high GCV values and high heritability values. The number of tillers and days to maturity could be chosen as selection criteria for assembling superior varieties. Both traits performed high heritability estimates and significant genotypic correlation with grain yield.

“…Based on the data analysis, the traits observed in each line showed a different effect in each line. Compared to another study, research by Kartahadimaja et al (2021) reported that statistical analysis of agronomic traits in 12 (twelve) rice genotypes showed that plant height, number of tillers, number of productive tillers, flag leaf width, flag leaf length, and flag leaf angle showed significant variation. Meanwhile, Kasim et al (2020) showed that the rice plant height of the 17 rice varieties ranged from 95-160 cm.…”

“…The same reference also stated that the shape of the rice grain is one of the determinants of rice grain quality. Grain quality is one of the selection parameters in plant breeding programs (Kush and Cruz 2000;Kartahadimaja et al 2021). Compared with the same line in the previous study (Oktaviani et al 2021), the dehulled rice size of F7 lines did not significantly differ from the F6 ones.…”

A comprehensive understanding of the genetic parameters and the interrelationship among characters in the breeding population is crucial for selecting low amylose and high antioxidant black rice varieties. Meanwhile, dehulled rice morpho-biochemistry profile can be used to determine the grain quality of F6 and F7 lines of Black Rice x Mentik Wangi var. The objectives of this study were to determine the agronomic traits, figure up the genetic parameters, describe the relationship among agronomic characteristics of the F6 lines, and determine the morpho-biochemical profile of F7 dehulled rice. Agronomic traits showed a difference in each line. Genetic parameters in each trait showed various categories. Path analysis showed that the number of tillers affected the dry weight and grain weight per panicle, but the plant dry weight did not directly affect the weight of 1,000 grain. Directly, the weight of 1,000 grain was only significantly affected by the grain weight per panicle trait. The F7 lines had a difference in grain length and amylose content. The dehulled rice color of the two lines showed the combination of the two parents. Based on the student T-test conducted on F6 and F7 grain, there was no difference in antioxidant content between the two sample groups. The antioxidant activity of all lines was in the range between the antioxidant activities of the two checked varieties. Although further research is still needed, the lines have the potency to be developed as low amylose pigmented rice.

“…Morphological information, for plant breeders, is not only used to see the morphological similarities between the watermelon plants tested, but also to obtain genetic information about the relationship between the watermelon plants tested (Gichimu et al 2009). In the assembly of varieties, information on the relationship between breeding materials plays an important role in the efficient selection of parents through plant breeding programs (Choudhary et al 2012;Kartahadimaja et al 2021). Breeding materials with distant relatives are needed to determine the parents of the cross to assemble the desired variety (Gbotto et al 2016).…”

Abstract. Amzeri A, Badami K, Pawana G, Alfiyan Syah M, Daryono BS. 2021. Phenotypic and genetic diversity of watermelon (Citrullus lanatus) in East Java, Indonesia. Biodiversitas 22: 5223-5230. The assembly of hybrid watermelon (Citrullus lanatus Thumb.) varieties with superior characters is an effort to meet the needs of watermelon seeds in Indonesia and reduce dependence on imports of watermelon seeds. The morphological characterization of exploratory watermelon plants is needed to support the assembly of superior varieties because morphological characterization will reveal the characteristics of each watermelon tested. In addition, the genetic and phenotypic diversity coefficients, heritability, and correlation between characters are needed to support the assembling of the desired variety. This research aimed to determine morphological diversity, genetic and phenotypic diversity coefficients, heritability, and correlation among characters of watermelon from East Java, Indonesia. The research used a randomized complete block design with ten genotypes as treatment and three replications,. The observed morphological characters were quantitative and qualitative characters. The number of characters was 60 characters. Eight quantitative characters, i.e., flowering date, harvesting date, fruit length, fruit diameter, skin thickness, fruit total soluble solids, number of seeds, and fruit weight were used to calculate the genetic and phenotypic diversity coefficient, heritability, and correlation between characters. Quantitative character data were subjected to analysis of variance, followed with a Duncan Multiple Range Test (p<0.05). The results showed that (i) Grouping based on morphological characters produces dendrograms with similarity coefficients ranging from 0.58 to 0.86 or there was a morphological diversity of 0.14 to 0.42, (ii) The phenotypic diversity coefficient (PDC) was greater than the genotypic diversity coefficient (PDC) in all observed quantitative characters, (iii) The broad sense Heritability values ?? of the tested watermelon genotypes ranged from 0.33 to 0.99, (iv) Fruit weight was significantly and positively correlated with fruit diameter, skin thickness, and number of seeds, (v) G1, G2, and G6 were the genotypes that can be used as parents to assemble superior watermelon varieties.
