ABSTRACT Cowpea is a tolerant crop to water deficit, with moderate protein and mineral contents, as well as fast cooking, which are important requirements for semi-arid regions. This study aimed to evaluate the retention of total proteins and minerals after cooking in cowpea genotypes, in order to select those that best preserve these nutrients contents. Twenty-four genotypes were evaluated, being ten lines, five commercial cultivars and nine landraces maintained by farmers. Cooking had a reduced effect on the contents of protein, potassium, calcium, iron and zinc in cowpea grains, with significant effects only in a few genotypes. A significant and positive correlation was observed only for grain yield x zinc content and protein content x cooking time. The line CPCR3F6L17 presented a high grain yield and high levels of protein, potassium, iron and zinc after cooking, showing to be a promising option for the studied region.

Multi-environmental trials have significant main effects and significant multiplicative genotype ? environment (GE) interaction effect. Principal coordinate analysis (PCOA) offers a more appropriate statistical analysis to deal with such situations, compared to traditional statistical methods. Eighteen bread wheat genotypes were grown in four semi-arid regions over three year seasons to study the GE interaction and yield stability and obtained data on grain yield were analyzed using PCOA. Combined analysis of variance indicated that all of the studied effects including the main effects of genotype and environments as well as the GE interaction were highly significant. According to grand means and total mean yield, test environments were grouped to two main groups as high mean yield (H) and low mean yield (L). There were five H test environments and six L test environments which analyzed in the sequential cycles. For each cycle, both scatter point diagram and minimum spanning tree plot were drawn. The identified most stable genotypes with dynamic stability concept and based on the minimum spanning tree plots and centroid distances were G1 (3310.2 kg ha-1) and G5 (3065.6 kg ha-1), and therefore could be recommended for unfavorable or poor conditions. Also, genotypes G7 (3047.2 kg ha-1) and G16 (3132.3 kg ha-1) were located several times in the vertex positions of high cycles according to the principal coordinates analysis. The principal coordinates analysis provided useful and interesting ways of investigating GE interaction of barley genotypes. Finally, the results of principal coordinates analysis in general confirmed the breeding value of the genotypes, obtained on the basis of the yield stability evaluation.

In the present investigation, 10 parents and their 45 crosses (half diallel) along with 2 standard checks (Rajendra Nilam and Rajendra Mahsuri-1) were evaluated during Kharif, 2018 in Randomized Complete Block Design (RCBD) with 3 replications at Rice Farm Section, Dr. Rajendra Prasad Central Agricultural University (RPCAU), Pusa, Bihar. The objective of this study was to identify promising rice genotypes having desirable combination of morphological traits along with high grain iron and zinc content and high grain yield potential. The results of variability parameters indicated that ample amount of genetic variability was present for all the studied traits. Most of the traits showed high heritability coupled with high genetic advance indicating fruitfulness of selection for improvement of these traits. One genotype (P2×P7) with high grain iron (16.10 ppm) and grain zinc (26.40 ppm) content along with high yield (43.12 g/plant) was identified. Genotypes with high grain iron coupled with high grain yield (P7×P9, P8×P9, P5×P7 and P5×P9) and high  grain zinc content coupled with high grain yield (P4×P7, P9×P10, P8×P9 and P5×P7) were also identified. These promising genotypes identified can be used further in breeding programmes to obtain superior segregants with high grain micronutrient content and high grain yield.

Potential Use

The potential use of common bean land cultivars with respect to their agronomic performance, cooking time and nutritional quality has scarcely been evaluated in breeding programs. The objective of the present study was to evaluate 19 common bean land cultivars for their agronomic traits, cooking time, and mineral concentration in grains to identify cultivars for potential use by a higher number of farmers or even breeding programs. Two field experiments were conducted in Alegrete and Santa Maria, Rio Grande do Sul (RS), Brazil, in the 2012/2013 season. The experimental design consisted of randomized blocks with three replications. A total of 23 cultivars were evaluated; 19 land cultivars were obtained from smallholder farmers from RS, and there were four control cultivars (Carioca, Pérola, Valente, and Guapo Brilhante). The traits evaluated included the cycle, insertion of the first pod, grain yield, cooking time, and concentrations of calcium, iron, zinc, and copper in the grains. The data were subjected to joint variance analysis, Pearson correlation analysis, and the Z index. The common bean cultivars showed differences in the cycle, insertion of the first pod, grain yield, cooking time, calcium, iron, zinc, and copper concentrations in grains, and the Z index. The cultivars Preto Miúdo and Cavalo Rajado had a high grain yield, i.e., greater than 2,900 kg ha-1. The land cultivars were classified as having early and intermediate cycles, and all had cooking times less than 30 min. Palha Roxa, Carioca Vermelho, and Perdiz had high concentrations of calcium, iron, zinc, and copper in the grains, an intermediate cycle, and low grain yield. Positive correlations of moderate magnitude were observed between the calcium and iron (r= 0.597), iron and zinc (r= 0.570), and zinc and copper (r= 0.548) concentrations. Indirect selection for high iron or zinc concentrations in grains will be effective for obtaining common bean cultivars with a higher nutritional quality. A cross between Carioca Santa Maria and Guapo Brilhante cultivar is recommended to obtain segregants with high agronomic performance, fast cooking, and high minerals concentration of in the grains.

The objective of this study was to estimate the direct and indirect effects of agronomic and culinary traits on iron and zinc contents in 11 cowpea populations. Correlations between traits were estimated and decomposed into direct and indirect effects using path analysis. For the study populations, breeding for larger grain size, higher number of grains per pod, grain yield, reduced cooking time, and number of days to flowering can lead to decreases in the levels of iron and zinc in the grain. Genetic gains for the iron content can be obtained by direct selection for protein content by indirect effects on the number of grains per pod, 100-grain weight and grain yield. The positive direct effect of grain size and protein content on the zinc content indicates the possibility of simultaneous gain by combined selection of these traits.

Underground irrigation water, particularly saline, when in arid and semi-arid regions of India may contain toxic amounts of B, from a trace up to 10 mg B/l (Anon. 1981–82). Continuous use of such water for irrigation may lead to the accumulation of salts and B in soil and this creates toxicity problems. Kanwar & Mehta (1970) have reported that water containing 2 mg B/l is hazardous if used on heavy soils. For sandy loam soils of semi-arid tracts in India, Chauhan & Powar (1978) have reported reductions in the grain yield of wheat and pea at 4 and 6 mg B/l respectively, while under similar conditions grain yield of lentil and barley was reduced at 3 and 6 mg B/l respectively (Chauhan & Asthana, 1981). So far, few attempts have been made to evaluate the effect of boronated saline water on soil and crops, under different agroclimatic conditions. A study of the effect of boronated saline water on an important oil-seed crop, linseed, on alkaline sandy loam soil in the semi-arid region of Agra, India was therefore undertaken.

Multigrain biscuits were formulated by blending refined wheat flour with barley and buckwheat flours in the ratios of 100:0:0::WF:BF:BWF; :100:0::WF:BF:BWF; 80:20:0::WF:BF:BWF; 70:20:10::WF:BF:BWF;60:20:20::WF:BF:BWF;50:20:30::WF:BF:BWF; 40:20:40::WF:BF:BWF; 30:20:50::WF:BF:BWF. Incorporation of buckwheat flour led to increase in mean calcium, iron and zinc contents of the biscuits. Among the blends the highest mean calcium of 68.96 mg/100g, iron of 9.22 mg/100g, zinc of 5.28 mg/100g were observed in treatment T8 (30:20:50::WF:BF:BWF). In terms of taste and flavour scores,T8 (30:20:50::WF:BF:BWF) was also adjudged the best treatment for the development of multigrain biscuits, whereas highest colour score of 8.05, texture score of 7.96 and overall acceptability score of 7.95 were observed in T1 (100:0:0::WF:BF:BWF).Biscuits were stored for a period of 90 days during which there was a significant decline in mineral contents as well as sensory attributes. Economically, the blended biscuits were found to be cheaper as compared to commercially available multigrain biscuits.

The adverse effects of abiotic stresses have always restricted oilseed crop production, particularly in arid and semi-arid regions. On the other side, global climate change has led us to adapt planting dates and select tolerant cultivars to encounter the new climatic conditions. To evaluate the effect of late-season drought stress under different planting dates on rapeseed cultivars, an experiment was conducted as a factorial split-plot based on randomized complete block design in Karaj region- Iran, during 2015-2017. Planting date and irrigation treatments were considered in the main plots as factorial and cultivars were placed in subplots. Two planting dates were regular date (October 7) (PD1) and late planting date (November 6) (PD2). Irrigation was also carried out at two levels of normal irrigation (NI) and irrigation interruption from flowering stage onwards (II). Experimental cultivars included ES Hydromel, ES Alonso, ES Darko, ES Lauren, and Ahmadi. According to the results, late-season drought stress and delayed planting date reduced leaf relative water content (LRWC), total chlorophyll content (TCC), proline (LPC), and grain yield (GY), and increased stomatal resistance (SR), canopy temperature (CT), and leaf soluble carbohydrates (CLS) in rapeseed cultivars. The highest grain yield (4505.6 kg ha-1) was obtained in NI conditions and PD1. Significant interactions of planting date, irrigation, and cultivar on LRWC, SR, and CLS traits indicated that the ES Hydromel was the most tolerant hybrid cultivar with the highest LRWC and the lowest SR and CLS levels compared to other ones in unfavorable conditions of late-season drought stress and delayed planting. To confirm these results, cluster analysis led to the formation of two clusters, where ES Darko, Ahmadi, and ES Lauren cultivars were placed in the sensitive cluster and ES Hydromel and ES Alonso cultivars were assigned to the tolerant cluster. Therefore, ES Hydromel can be introduced as a superior cultivar to be selected as a genotype that presents acceptable resistance under drought stress and late sowing in arid and semi-arid regions.

Nutri-millets offer copious micronutrients like vitamins, beta-carotene etc. In this present day, all the millets are amazingly superior and are therefore, the result for the malnutrition and obesity that affects a vast majority of the Indian population. They have numerous beneficial properties like drought resistant, good yielding in areas where water is limited and they possess good nutritive values. The prospective water scarcity in semi-arid regions disturbs both normal as well as managed environments, which limits the cultivation of crops, fodder, and other plants. The issues faced by the rain-dependent farming of these semi-arid regions are primarily the unpredictability of the monsoon. Probability analysis of rainfall events are believed to contribute in deciding sowing dates for the current season and for successful crop production in semi-arid environments. The present study was carried out in semi-arid condition to quantify the performance of nutri-millets in the rain dependent farming. The experiment was laid out under factorial randomized block design with 3 replications. The treatments comprises of crop factor viz., Sorghum [Sorghum bicolor (L.) Moench] (C1) and, little millet [Panicum sumatrense Roth ex Roem. & Schult] (C2) and sowing window factor viz., sowing based farmer’s practice (M1) i.e. on 31st standard meteorological week (SMW); Sowing at 33rd SMW based on 50% rainfall probability (M2); Sowing at 38th SMW based on 75% rainfall probability (M3), Sowing window as per the current weather forecast, for this season on 35th SMW (M4).It is evident from the study that Sowing sorghum at 38th standard meteorological week based on 75% rainfall probability recorded higher grain yield, rain water use efficiency with elevated iron and calcium content. This shows that different sowing dates have significant influence on grain yield and quality of nutri-millets.
