An experiment was conducted using 60 chilli germplasm in the experimental field of Plant Genetic Resources Centre (PGRC), Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur during winter 2013-14 to characterize the germplasm based on morphological traits. Data were recorded as per the descriptor developed by Biovarsity International (BI) and Minimal Descriptor of Agri-Horticultural Crops. The germplasm were collected from different parts of Bangladesh and evaluated for 22 qualitative and 5 quantitative characters. Distinct variation among the germplasm was observed in all the qualitative parameters except cotyledonous leaf shape and fruit persistence. The maximum variation was observed in fruit colour both at mature and immature stage. Fruit colour was observed in four categories, namely green, black, green with blackish blush and dark green. The germplasm AMS-42, AMS-45, RI-35 and AH-5 showed black coloured fruit indicating their high carotenoid content. Leaf pigmentation was found in AMS-39, AMS-44, AMS-45, AH-1and RI-2 germplasm. Purple coloured corolla observed in AMS-42, AMS-45, AH-1 and AH-2 showing their high pollen fertility. The highest quantitative variation was observed in yield per plant suggesting that the evaluated germplasm could be used in developing high yielding variety. Considering the yield and yield contributing parameters the germplasm AI-1, AI-2 and RI-2 were found better among the 60 germplasm.Bangladesh J. Agril. Res. 42(2): 207-219, June 2017

Twenty-one sweet pepper genotypes from native and alien sources were characterized for twenty-six morphological traits using vegetative and reproductive appearances at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh from October 2018 to March 2019. Marked variation was exhibited among twenty-six qualitative traits (26) studied. Twenty-two (22) characters showed undeniable variation among the genotypes. The presence of higher percentage (61.90%) of light purple color at node were observed indicated high amount of anthocyanin content. Leaf shape is used as genotypes identifier at vegetative stage and herein three types of leaves were found with dark green color (76.19%) that is highly correlates with yield. In case of flower, same level of stigma exertion (61.90%) with 100% white color corolla indicates higher number of fruit sett were exhibited. Entire genotypes exerted one or more exclusive characters especially fruit shape and color in Bangladesh perspective which could be used as an important breeding tools. Fruit color was observed in various categories at intermediate and mature stage as for instance yellow, green, purple, orange, red etc. in addition higher percentage of blocky fruit shape (38.09%) were observed and these are the consumer fascinating attributes of sweet pepper. However, selection of genotypes with desirable morphological trait can be used for their exploitation of future breeding programme.

Flax (Linum usitatissimum L.), grown throughout the world for millennia. It is a multipurpose agricultural crop that can provide food, fuel and fibre. An agro-morphological characterization based on 13 traits of 26 flax accessions was carried out during the Rabi season 2017-2018 at the Agricultural Research Station, Bangladesh Agricultural Research Institute, Rangpur. The field experiment was laid out in a randomized completed block design having four replications. Flax seeds were sown in 3.0 m × 0.6 m plot with continuous line sowing (two lines). The seed germination (%) and vigour indices of all flax accessions varied from 44.1 – 77.7 and 44.1 – 119.4, respectively. A significant variation in all growth and yield attributing descriptors was observed except 1000-seed weight of flax. Among the accessions, BD-10708 possessed the highest seed yield (182.9 g plant–1) and yield attributing descriptors viz., number of capsules plant–1 (142) and seeds plant–1 (513) of flax. The performance of the local accesson Ulipur was observed poor compared to some of the test accessions of flax. Some of these flax accessions could be used as breeding materials in varietal developmental and improvement programmes with higher yield potentials of flax in Bangladesh.

Ginseng plant (Phytolacca octandra L.) is a wild plant that has the potential to be used as medicine. The morphological characteristics of ginseng plants in Indonesia are different. Therefore, it is necessary to carry out research aimed at characterizing the morphology and phytochemical screening of ginseng (P. octandra L.) leaves and tubers. The research was conducted first by observing morphological characters and screening phytochemical compounds such as alkaloid test, flavonoid test, phenol test, tannin test, saponin test, terpenoid test, and steroid test. The results of the research on the morphological characterization of ginseng (P. octandra L.) were: having a taproot which was modified into a tuber, a round, smooth, red color, pointed leaf shape, the base and tip of the leaf were pointed, buni fruit type, round flat, colored blackish-purple when ripe, a compound flower is located at the end of the branch and has flat, round seeds. Ginseng tubers have triterpenoid and saponin compounds, while the leaves only have saponin compounds. The potential development of ginseng (P. octandra L.) is currently limited as traditional medicine by local people. This is due to limited knowledge in its development efforts and unknown phytochemical content.

In this research, morphological characterization of vineyard peach collection was conducted. In 78 accessions thirty qualitative traits of tree, flower, leaf, fruit and stone were analysed by using UPOV and ECPGR descriptors. Most of the studied traits showed a high degree of variability. The lowest variability obtained for the leaf traits, and highest for skin and flesh colour. Not only were the accessions sorted into a large number of categories by the most of their properties, but also there was a significant level of variability in the collection, reflecting in the fact that the traits were recombinant in a different way. Principal component analysis (PCA) and a dendrogram were performed to determine relationships among accessions and to obtain information on the usefulness of those characters for the discrimination. The PCA revealed that the first 4 principal components were able to represent 43.1% of total variance. Traits with high discriminating values comprised internal and external fruit colour, flower type and colour, flower bud density and stone shape. The cluster analysis showed that the accessions were placed in three main clusters. The greatest impact on the separation in clusters had fruit over colour and extent of fruit over colour. Moreover, the collection can also comprise some accessions with the preferred recombination of properties that might be interesting for further studies in breeding.

Farmers from the district of São Pedro de Joselândia, belonging to the municipality of Barão de Melgaço, Pantanal of Mato Grosso, have been cultivating for some time two rice plant materials and three types of beans that, according to them, are not commercial. For this reason, the objective of this work was to test the originality of the materials by means of genetic and morphological characterization in order to identify whether the nature of the subsamples would be effectively traditional or whether they are varieties already known in the market. Morphological analyzes of the cultivated plants (phenotypic characteristics, cycle and flowering) and seed of the rice subsamples, hereinafter called Agulhinha Vermelho and Branquinho and of the Amarelinho, Rosinha and Roxinho subsamples were performed. Also, the evaluation of distribution of comparative genetic variability with other materials of the same species, already cataloged, was determined. The subsamples were characterized as traditional varieties different from those already cataloged and they are not found in the Nuclear Collection of Rice and Beans of the Brazilian Agricultural Research Corporation (Embrapa). They have distinct morphological characteristics, being potential species for use in the market of new technologies. This should guarantee to the residents of that community that they are breeders of specific materials of cultural heritage adapted to the local conditions.

The tendency to prioritize food crops, such as rice and wheat, to meet human needs has resulted in dependence, degradation, and loss of local knowledge. In this term, biology education plays its role by exploring the potential of local plants, including their use as learning resources. One of those local plants is the taro plant (Colocasia Esculenta L.), an alternative staple food for those who live in Eastern Indonesia. The research method used was qualitative research. The data collection techniques included observation, interviews, characterization, and questionnaires. The data collected were analyzed through descriptive analysis. The morphological characterization of taro was done based on Descriptors for Taro IPGRI (International Plant Genetic Resources Institute). The poster development procedure used was the ADDIE model. The results of the exploration showed five local taro accessions that had variations in morphological characters. The plant range was directly proportional to the plant height. There was one accession that was tall (AT 5) and had the potential to be cultivated on a large scale. Most of the leaves were green, while the leaf vein color was varying, namely white, green, and purple, with harvesting periods ranging between 4 to 9 months. The leaf vein pattern has a shape like a letter Y. Five accessions had petiole cross-sections, a waxy coating on the leaf surface, and predominantly white intervenii. The assessments of material experts, media, and users showed that the poster was feasible, usable as a biology learning resource.

Oilseed Breeding

Rapeseed and mustard , the two important oleriferous Brassicae grown in India play a magnanimous role in the national market of edible oils and meals. But the production of the crop is low due to a narrow genetic base. Much effort has been put to diversifying the oilseed breeding. The morphological characterization is the first step towards diversity analysis and conservation of plant genetic resources. A major challenge facing those involved in the testing of new plant varieties for Distinctness, Uniformity, and Stability (DUS) is the need to compare them against all those of ‘common knowledge. Protection of Plant varieties and Farmer’s Right Act insists on Distinctness, Uniformity, and Stability (DUS) characterization of new varieties and recommends the registration of varieties for any one specific novel character. On this backdrop, the present experiment was carried out to evaluate 54 Brassica rapa L. genotypes for DUS characterization under randomized complete block design ( RCBD) with three replication at the experimental farm of GPB, FoA SKUAST-K, Wadura during rabi 2019-2020. The results of the study revealed wide variation in various traits among different Brassica rapa genotypes L. The assessment of 54 genotypes for 09 traits revealed that all the traits were informative with respect to trait expression cum characterization. The different characters studied were having great impact for selection of superior genotypes for further breeding programmes. Hence, the diversity observed among the genotypes could be utilized for cultivar improvement and germplasm conservation programs aimed at improving productivity in Brassica rapaL
