“…of fruits/ plant (97.09%, 84.22%), fruit yield per plant (96.86%, 67.95%) indicating strong influence of additive gene action and phenotypic selection is effective for these traits. Analogous observations were found by Lekshmi and Celine (2017) [3] and Ritonga et al, (2018) [6] . The knowledge about the nature and level of inter-relationship of yield and other components is very valuable because selection based on one trait may directly or indirectly affect the performance of another trait.…”

The present study was carried out with fourteen genotypes of tomato at Polyhouse Complex, Department of Horticulture (Veg. & Flori.), BAU, Sabour during 2018-2019 to assess the genetic variability and character association for yield and attributing traits in tomato (Solanum lycopersicum L.) genotypes for protected conditions. The experiment was laid out in randomized block design with three replications. Data were recorded for sixteen morphological traits and five biochemical traits. The experimental results revealed considerable differences among the genotypes for all the traits except titratable acidity and βcarotene. Higher phenotypic and genotypic coefficients of variation (PCV and GCV) were observed for no. of flowers/truss, no. of locules/fruit, no. of fruits/truss, fruit yield/plant, no. of fruit/plant, average weight of fruit, final plant height, titratable acidity, lycopene, ascorbic acid and β-carotene indicating phenotypic selection for these traits was effective for enhancement. High heritability together with high genetic advance as % of mean was observed in all traits except days to fruit picking. Based upon correlation and path coefficient analysis characters like no. of flower /truss, equatorial diameter, pericarp thickness and no. of fruit /plant could be reliable selection parameters for evolving high yielding genotypes.

“…Fruit weight per plant is a character that is very much considered in tomato cultivation. Fruit weight per plant is known to have a high and positive correlation with fruit weight (Ritonga et al 2018), so the improvement of one character will affect the other characters.…”

Abstract. Mawasid FP, Syukur M, Trikoesoemaningtyas. 2019. Epistatic gene control on the yield of tomato at medium elevation in the tropical agroecosystem. Biodiversitas 20: 1880-1886. Cultivation of tomatoes on the middle-low plain generally decreases the quantity and quality of the yield due to high-temperature stress. Increasing the size and weight of lowland tomatoes is needed to enhance national production. Information on the action and genetic model of target characters is needed in the preparation of the assembly program, especially for selection needs. This study aims to obtain genetic information and heritability of tomato yield characters, as a basis for assembling large tomato varieties for the lowlands. The study was conducted using six populations (P1, P2, F1, BCP1, BCP2, and F2) resulting from two different crosses of 99D x Tora (C-I) and 97D x Tora (C-II). The results show that the action of non-additive genes and non-allelic interactions has a large value, with duplicate epistasis being more dominant than complementary epistasis. Duplicate epistasis was found in the character of harvest time, fruit length, fruit diameter, fruit weight in cross I and flowering time, harvest time, fruit length, fruit diameter, and number of fruits in cross II, while complementary epistasis was found in flowering time, fruit weight per plant, number of fruits in cross I, and fruit weight, fruit weight per plant in cross II. Moderate to high heritability was found in the character of fruit length, fruit diameter, fruit weight, and fruit weight per plant. The values are higher in population from the cross I (99D x Tora) for each character, indicating that the cross I has a higher potential for genetic progress than cross II. Selection is recommended when the homozygosity has increased, using the Bulk method or Single Seed Decent. The two methods above can maintain variability in the next generation, so epistasis genes that control target characters are not drastically eliminated.

“…Extensive genetic diversity and high heritability is an indication of the high chance of success in assembling new superior sweet potato varieties that have better potential in quality and quantity. Information about genetic diversity, heritability and character relationships between quantitative characters and crop yields are very important in crop improvement (Ritonga et al 2018).…”

Dewi R, Utomo SD, Kamal M, Timotiwu PB, Nurdjanah S. 2019. Genetic and phenotypic diversity, heritability, and correlation between the quantitative characters on 30 sweet potato germplasms in Lampung, Indonesia. Biodiversitas 20: 380-386. Local food commodities such as sweet potato is an alternative rice substitute food which has high nutritional content. Estimating the value of genetic diversity, heritability and correlation between quantitative characters with the weight of large storage root per plant, is needed in the selection program for the development of quality sweet potato varieties. The purpose of this study was to find out information about genetic diversity, heritability, and correlation between quantitative characters with the weight of large storage root in 30 local Lampung sweet potato germplasm, introduction and national superior genotypes. The study was carried out in the Politeknik Negeri Lampung experimental garden from September 2017 to January 2018. Using 30 genotypes of sweet potato germplasm. The study was arranged in a randomized block design (RBD) with two replications. The results showed that all characters (weight of large storage root, number of large storage root, storage root length, storage root diameter, vines length, segment length, vines diameter, and weight of vines) had a value of genetic diversity, whereas wide phenotypic diversity and has a high value of heritability. Genetic factors more influence all characters in this study compared to environmental factors. The results of the correlation analysis showed that the characters of the weight of large storage root, storage root length, and storage root diameter were positively correlated with the weight of the storage root. Whereas, the length of vines is negatively correlated with the weight of large storage. The character of the segment length, vines diameter and weight of vines did not correlate with the weight of large storage root. The character of the segment length, vines diameter and weight of vines did not correlate with the weight of large storage root. Cluster analysis results from 30 sweet potato genotypes were grouped into 13 clusters. Based on similarity of character and provenance. The germplasm of 30 Sweet potato genotypes found in Politeknik Negeri Lampung can be selected and crossed to create the desired superior characters.
