Background: French bean (Phaseolus vulgaris L.) is an important protein-rich winter vegetable of our country but extensively grown in south Chhotanagpur plateau of Jharkhand during both kharif and rabi seasons. However, indiscriminate uses of agrochemicals lead to production of poor quality pods of the crop due to residual toxicity. Hence, the current study was aimed to evaluate of the crop varieties based on their yield and quality traits expression under organic growing condition.Methods: The present investigation was carried out by adopting five bush type varieties of French bean (V1: Arka Komal, V2: Swarna Priya, V3: HAFB-2, V4: HAFB-4 and V5: Falcon). They were grown independently under two growing conditions viz. organic farming (Oi) where FYM, vermicompost and Shasyagavya were used as organic inputs and absolute control (O0) where no organic input was applied. These varieties were grown with their four replications in each of the experimental situate following RCBD experimental design. Different yield and its attributes and proximate quality traits were studied under both growing conditions for their evaluation.Result: Findings revealed that most of the studied traits were influenced by organic growing condition with significant differences among varieties to pod length, pods per plant, pod weight, green pod yield, ascorbic acid, TSS and protein content. Consequently, the maximum green pod yield (17.55 t ha-1) was estimated in HAFB-4 under organic growing condition as against 7.57 t ha-1 under the absolute control condition. Different proximate quality traits were also expressed independently under different varietal situates but responded better under organic growing condition than its respective absolute control counterpart.

The present investigation was conducted during rabi seasons of 2016-17 and 2017-18 in the organic experimental farm of the institute by employing French bean cv. Swarna Priya. The experiment was designed after RCBD considering five organic treatments, viz.T1: Amritjal (1%); T2: Sanjivani (10%); T3: Shasyagavya (10%); T4: FYM @ 6 t ha-1 + Vermicompost @ 3t ha-1; and T5: Absolute Control. Different growth, yield and quality attributes of the crop were highly influenced by different organic treatments. In this context, T3: Shasyagavya (10%) emerged as the best treatment with the highest green pod yield of 21.15 t ha-1. However, quality contributing characters performed indifferently under the exposures of organically designed treatment conditions. Though, T3 (Shasyagavya 10%) once again materialized as the best treatment with higher amount of dry matter (9.54%), TSS (4.600Brix), ascorbic acid (65.27 mg 100g-1) and protein content (10.63 %) in edible green pods, respectively.

AbstractPlant quality trait improvement has become a global necessity due to the world overpopulation. In particular, producing crop species with enhanced nutrients and health-promoting compounds is one of the main aims of current breeding programs. However, breeders traditionally focused on characteristics such as yield or pest resistance, while breeding for crop quality, which largely depends on the presence and accumulation of highly valuable metabolites in the plant edible parts, was left out due to the complexity of plant metabolome and the impossibility to properly phenotype it. Recent technical advances in high throughput metabolomic, transcriptomic and genomic platforms have provided efficient approaches to identify new genes and pathways responsible for the extremely diverse plant metabolome. In addition, they allow to establish correlation between genotype and metabolite composition, and to clarify the genetic architecture of complex biochemical pathways, such as the accumulation of secondary metabolites in plants, many of them being highly valuable for the human diet. In this review, we focus on how the combination of metabolomic, transcriptomic and genomic approaches is a useful tool for the selection of crop varieties with improved nutritional value and quality traits.

About one-third of the world’s barley crop is used for malt production to meet the needs of the brewing industry. In this regard, the study of the genetic basis of malting quality traits and the breeding of malting barley varieties that are adaptive to their growing conditions are relevant throughout the world, particularly in the Russian Federation, where the cultivation and use of foreign malting varieties of barley prevails. The main parameters of malting quality (artificially germinated and dried barley grains) are malt extract, diastatic power, Kolbach index, viscosity, grain protein, wort β-glucan, free amino nitrogen, and soluble protein content. Most of these components are under the control of quantitative trait loci (QTLs) and are affected by environmental conditions, which complicates their study and precise localization. In addition, the phenotypic assessment of malting quality traits requires elaborate, expensive phenotypic analyses. Currently, there are more than 200 QTLs associated with malting parameters, which were identified using biparental mapping populations. Molecular markers are widely used both for mapping QTL loci responsible for malting quality traits and for performing marker-assisted selection (MAS), which, in combination with conventional breeding, makes it possible to create effective strategies aimed at accelerating the process of obtaining new promising genotypes. Nevertheless, the MAS of malting quality traits faces a series of difficulties, such as the low accuracy of localization of QTLs, their ineffectiveness when transferred to another genetic background, and linkage with undesirable traits, which makes it necessary to validate QTLs and the molecular markers linked to them. This review presents the results of studies that used MAS to improve the malting quality of barley, and it also considers studies that searched for associations between genotype and phenotype, carried out using GWAS (genome-wide association study) approaches based on the latest achievements of high-throughput genotyping (diversity array technology (DArT) and single-nucleotide polymorphism markers (SNPs)).

Yield And Quality

French bean [Phaseolus vulgaris (L.)] is among the leading export vegetable in Africa, mostly produced by small-scale farmers. Unfavorable environmental conditions and heavy infestations by insect pests are among the major constraints limiting production of the crop. Most French bean producers grow their crop in open fields outdoors subject to harsh environmental conditions and repeatedly spray insecticides in a bid to realize high yield. This has led to rejection of some of the produce at the export market as a result of stringent limits on maximum residue levels. Two trials were conducted at the Horticulture Research and Teaching Field, Egerton University, Kenya, to evaluate the potential of using agricultural nets (herein referred to as agronets) to improve the microclimate, reduce pest infestation, and increase the yield and quality of French bean. A randomized complete block design with five replications was used. French bean seeds were direct-seeded, sprayed with an alpha-cypermethrin-based insecticide (control), covered with a treated agronet (0.9 mm × 0.7 mm average pore size made of 100 denier yarn knitted into a mesh impregnated with alpha-cypermethrin), or covered with an untreated-agronet (0.9 mm × 0.7 mm average pore size made of 100 denier yarn knitted into a mesh not impregnated with insecticide). Alpha-cypermethrin and agronets were manufactured by Tagros Chemicals (India) and A to Z Textile Mills (Tanzania), respectively. Covering French bean with the agronets modified the microclimate of the growing crop with air temperature increased by ≈10%, relative humidity by 4%, and soil moisture by 20%, whereas photosynthetic active radiation (PAR) and daily light integral (DLI) were decreased by ≈1% and 11.5%, respectively. Populations of silverleaf whitefly [Bemisia tabaci (Gennadius)] and black bean aphids [Aphis fabae (Scopoli)] were reduced under agronet covers as contrasted with control plots. Furthermore, populations of both pests were reduced on French bean grown under impregnated agronets compared with untreated agronets, but only on three of the five sampling dates [30, 44, and 72 days after planting (DAP)] for silver leaf whitefly or at only one of the five sampling dates (30 DAP) for black bean aphid. Covering French bean with agronets advanced seedling emergence by 2 days and increased seedling emergence over 90% compared with control plots. French bean plants covered with both agronet treatments had faster development, better pod yield, and quality compared with the uncovered plants. These findings demonstrate the potential of agronets in improving French bean performance while minimizing the number of insecticide sprays within the crop cycle, which could lead to less rejection of produce in the export market and improved environmental quality.

To obtain high chia seed yields and seed qualities, a suitable crop management system needs to be developed for the given growing conditions in southwestern Germany. Field experiments were conducted at the experimental station Ihinger Hof in two consecutive years (2016, 2017). The study aimed to evaluate yield and quality traits of chia depending on different (i) row spacing (35, 50 and 75 cm), (ii) sowing densities (1, 1.5 and 2 kg ha−1) and, (iii) N-fertilization rates (0, 20 and 40 kg N ha−1). It consisted of three independent, completely randomized field experiments with three replications. Results showed that chia seed yields ranged from 618.39 to 1171.33 kg ha−1 and that a thousand seed mass of 1.14 to 1.24 g could be obtained. Crude protein-, crude oil- and mucilage contents varied from 18.11–23.91%, 32.16–33.78% and 10.00–13.74%, respectively. Results indicated that the year of cultivation and the accompanied environmental conditions, like precipitation or temperature, influenced the determined traits more than the applied agronomic practices. As average seed yields exceeded those obtained in the countries of origin (Mexico, Guatemala) while having comparable quality characteristics, chia holds great potential as an alternative crop for farmers in southwestern Germany.

The effect of seed biopriming with different bioagents including plant growth promoting rhizobacteria (PGPR-1), rhizobial biofertilizer (Rhizobium strain B1) and biological control agent (Trichoderma viride) was observed on plant growth, seed yield and incidence of diseases in French bean cv. Contender conducting a field experiment during kharif season in the year 2017 and 2018. Under field conditions in both the years, field emergence (95.18 %), plant height at 30 days after sowing (34.09 cm), plant height at final harvest (56.99 cm), days to pod harvest (52.33), harvest duration (18.67), pod length at final harvest (16.83 cm), number of pods per plant (20.17), dry pod weight (2.72 g), pod yield per plant (38.64 g), number of seeds per pod (7.17), seed yield per plant (20.76 g), seed yield per plot (875.33 g), seed yield per hectare (23.34 q), 100 seed weight (34.19 g), quality of harvested seeds were recorded significantly higher after seed biopriming with PGPR-1+ Rhizobium strain B1 (T4) as compared to carbendazim seed treatment and untreated control. This treatment combination also reduced the incidence of major diseases like, Rhizoctonia root rot and Angular leaf spot significantly as compared to carbendazim seed treatments and untreated control. It can be concluded from the present investigation that seed biopriming of French bean cv. Contender with PGPR-1+Rhizobium strain B1 @ 109cfu/ml for 8 hours was an effective treatment which significantly improved plant growth, pod yield, seed yield, seed quality and seed vigour and reduced disease incidence as compared to seed treatment with carbendazim @ 0.2% as well as untreated control under field conditions.

Ethnicity plays a strong role in niche market development, and the Asian market is currently underserved. As Asian populations continue to grow in Mississippi, especially along the Gulf Coast, it is important to recognize new market opportunities. The fruit and vegetables desired by the diverse Asian population are often unavailable or of poor quality as a result of extensive shipping distances. Mississippi growers can meet this need for fresh Oriental produce at a higher price than traditional vegetables. Yardlong bean or asparagus bean (Vigna unguiculata ssp. sesquipedalis) is the same species as cowpea. The cultural practices for yardlong bean are similar to that of traditional pole beans (Phaseolus vulgaris). However, there is still much to be learned about this crop in terms of pest management, disease susceptibility, and varietal superiority. The objectives of this research were to compare length and yield of eight yardlong bean varieties and collect observational data regarding production practices. Four replications of eight yardlong bean varieties were grown at Beaumont, MS, during Summer 2001 and 2002. Beans were grown on 4-ft-wide trellises 1 ft above the soil line. Beans were harvested twice per week. Highest marketable yields were attained with the varieties Red Seed and Black Seed, which are best suited for growing conditions in southern Mississippi. However, mosaic viruses may pose a potential production problem, and further research is warranted to determine best cultural practices and pest management.

Three pole-type French bean (Phaseolus vulgaris L.) genotypes (Four season, Trishuli & Makwanpur) were sown in different three dates, i.e., August 16, 31 and September 15 during autumn seasons of 2010 and 2011 at the Agriculture Research Station, Malepatan, Pokhara (848 msl) to assess the fresh pod yield and yield attributes of the genotypes in different dates of sowing. The experiment was conducted in randomized complete block design with three replications. The temperature ranged from 14° to 32°C during the growth period. The results showed significant variations in fresh pod yield and yield attributes. Flowering was earlier in Makwanpur genotype. About 50% plants flowered within 39 days in Makwanpur while it took more than 48 days for Trishuli. Tallest plants were produced by Makwanpur (271.7 cm) and shortest by Trishuli (256.2 cm). The pod length was highest (18.34 cm) in Four season and lowest in Makwanpur (15.07 cm). Pod width was highest in Trishuli (9.04 mm) and lowest in Makwanpur (7.10 mm). Highest fresh pod yield was produced by Four season (25.08 t/ha) followed by Makwanpur (23.11t/ha) and the lowest by Trishuli (19.97 t/ha). Sowing date also showed significant effect on yield and yield attributes. Earliest sowing (16 August) showed better results in early flowering (42.63 days), tallest plants (280.4 cm), longest pods (18.51 cm), widest pods (9.21 mm) and the highest fresh pod yield (31.13 t/ha) than 31 August and 15 September sown conditions. Fresh pod yield was highest in 16 August sown (31.13 t/ha) followed by 31 August (21.74 t/ha) and lowest in 15 September (15.29 t/ha). Four season sown on 16 August produced the highest fresh pod yield with an average of 35.35 t/ha. The result revealed that Four season is the best genotype and mid August is the appropriate sowing time for higher fresh pod yield of French bean in the mid hills of western Nepal.
