“…All S2 okra families (103 plants) had a tender texture at 8 DAA, 56.3% (44 plants) still had a tender texture at 9 DAA, and only 7.8% (8 plants) had a tender texture at 10 DAA. The increase in the fruit picking period indicates an improvement in the quality of okra fruit compared to the previous generation, as [8] reported. Ref [16] stated that the longer the okra fruit is harvested, the cells in the okra fruit will continue to undergo cell division and enlargement, causing differences in fruit size between harvest periods of 8 DAA, 9 DAA and 10 DAA.…”

“…Most S2 okra families have wide variability in the first flowering day, the number of flowers, the number of fruits and plant height (Table 2). Wide variability in these characters has also been reported previously in the S1 family [8]. Differences between okra families that show variations in each observed genotype indicate an opportunity to choose a genotype that performs better for each trait [12].…”

“…The F1 population revealed an increase in the picking period of up to eight DAA [1]. The F2 population showed improved picking time traits, revealing that 67.0% and 14.4% of the population have tender fruit textures up to eight and nine DAA, respectively [8].…”

Okra (Abelmoschus esculenthus L.) is a functional food crop consumed when the pod is immature and tender. Crosses the local okra, i.e. green and red okra, with introduced varieties B291 and Ve022 aimed to improve the local cultivar traits. This study aimed to assess the agronomic variability of S2 from a cross between green okra and red okra with introduced varieties and select superior families that can be used to produce new cultivars. The study used an experimental method with individual observation. There were 12 S2 families evaluated in this study. There were 12 S2 families evaluated in this study, derived from selfed-pollinated plants of the S1 families. Results showed that all S2 okra plants had tender fruit at 8 DAA, 56.3% and 7.8% of the entire population had tender fruit at 9 and 10 DAA, respectively. The increase in the fruit picking time was in line with the increase in size and weight of okra fruit. Variations in quantitative traits were observed, including flowering time, plant height, and the number of flowers and fruits in the S2 families. The performance of qualitative traits of the S2 families was uniform. There was a decrease in the quantitative trait of S2 families compared to the S1, which the inbreeding depression might cause. .1 and SOMVE022-10.1.8 families can be continued for further evaluation because they have a good quantitative trait performance.

“…A broad variability in picking time shows an opportunity to get plants whose fruit is still tender and not fibrous when the picking time is prolonged. Hayati et al (2021) reported that only a few plants had a picking time of 9 DAA, which are 14.4% and 67% at 8 DAA. All families had thick and fibrous fruit texture at harvested at 10 DAA.…”

Okra (Abelmoschus esculenthus) is a vegetable plant consumed in immature and tender texture fruits. Crosses of local okra with introduced varieties are carried out to improve the character of the local cultivars. This study aimed to assess the variability of agronomic characters, both quantitative and qualitative characters of various families of the F2 populations and select superior families that can be used to produce new cultivars. The F2 population was derived from inbreeding and selection of the crosses between local okra cultivars with B291 and Ve022 as introduced cultivars. The study used an experimental method with an individual observation. Qualitative characters were described based on the descriptor by IBPGR, while quantitative characters were analyzed using descriptive statistics. Results showed variation in each F2 family in plant height, the number of flowers per plant and the number of fruits per plant, except for SOMB291-16. FOHVE022-8, FOHB291-15, FOHVE022-17, SOMB291-23 and SOMB291-24 families could be selected due to the extended picking time were in line with the increase of fruit quality. A broad variability of quantitative characters was found for all characters, indicating a high opportunity to obtain valuable traits and desirable segregants in F2 populations. Variations in qualitative characters were found in stem color, leaf shape, fruit color and fruit shape. The selection of plants with specific characters could be maintained with inbreeding or self-pollinated desirable segregants.

Okra is a functional vegetable with high nutrient content and medicinal value potential. Evaluating genetic material from various genetic sources is a standard procedure in plant breeding programs. A field study was carried out to evaluate the agronomic traits of F2 populations derived from various types of varieties and assess the phenotypic variability of the traits. The research was conducted at the Research Station of the Faculty of Agriculture, Andalas University, from January to May 2021. The materials used are seeds from self-pollinated of 16 F1 populations with various varieties, i.e., hybrid, composite, introduced and local varieties. Data was collected based on an individual observation, and the data were then analyzed using descriptive statistics. Results showed that the entire population of the F2 derived from both hybrid or composite varieties, introduced or local varieties, has diverse agronomic traits, indicating their potential to be developed as parental inbred lines. All agronomic traits evaluated showed wide variability, indicating a high possibility to obtain plants with valuable and desirable traits. The exception was found for the optimum picking time; however, the optimum picking time 7, 8 or 9 DAA is sufficient to obtain fruit with higher fruit weight and fruit size.
