The present study was conducted to examine the growth performance and relative contribution of area and yield to the change in mungbean production in Rajasthan. Three districts, viz., Nagaur, Jodhpur, and Pali, which together contribute more than 50% of the total area under mungbean in Rajasthan, were selected for the study. Time series data were collected from 2000- 01 to 2019-20 and to study the decadal performance, the entire period was bifurcated into two sub-periods: 2000-01 to 2009-10 (sub-period I) and 2010- 11 to 2019-20 (sub-period II). The Compound Annual Growth Rate (CAGR), Cuddy Della Valle Index (CDVI), and Decomposition Analysis Model were employed for analysis. Results revealed that the growth rate was positive for area, production, and productivity of mungbean at the state and district levels. The instability index was found to be greater than 30 in most of the cases, which indicates the high variations in area, production, and productivity of mungbean during the reported period. The sub-period II witnessed a comparatively higher positive growth rate accompanied by a lower instability index than the sub-period I. The study further revealed that the area effect was greater than the yield effect in most of the cases, which indicates its greater share in the increase in mungbean production at state and sampled district levels. With the observed positive growth rate in area and its contribution to change in production, the state has scope to increase the area coverage under mungbean, as 55% of the districts in Rajasthan have less than 1% of the total area under cultivation.
本研究旨在研究拉贾斯坦邦绿豆产量变化的生长表现及其面积和产量的相对贡献。纳戈尔、焦特布尔和巴利三个地区占拉贾斯坦邦绿豆种植总面积的50%以上，被选为研究对象。选取2000-01年至2019-20年的时间序列数据，将整个时期划分为2000-01年至2009-10年(子期I)和2010- 11年至2019-20年(子期II)，采用复合年增长率(CAGR)、Cuddy - Della Valle指数(CDVI)和分解分析模型(Decomposition Analysis Model)进行分析。结果表明，在国家和地区层面上，绿豆的面积、产量和生产力均呈现正增长趋势。在大多数情况下，不稳定指数大于30，这表明在报告期内绿豆的面积、产量和生产力变化很大。子期II的正增长率相对高于子期i，且不稳定指数相对较低。研究进一步发现，在大多数情况下，面积效应大于产量效应，这表明其在州和采样区水平的绿豆产量增长中所占的份额更大。由于观察到绿豆面积的正增长率及其对生产变化的贡献，拉贾斯坦邦有空间增加绿豆种植面积，因为拉贾斯坦邦55%的地区的绿豆种植面积不到总面积的1%。

Seventy-three pigeon pea genotypes along with three checks were evaluated to assess genetic variability parameters, correlation and path coefficients among the yield and yield component traits. Analysis of variance showed significant difference for all the characters under study except number of seeds per pod and pod length. The maximum PCV and GCV were observed for days to maturity and days to 50% flowering while the minimum for number of seeds per pods. Heritability in broad sense was high for days to 50% flowering followed by biological yield per plant and seed yield per plant whereas high genetic advance as per cent of mean was observed for days to 50% flowering followed by days to maturity. Characters namely days to 50% flowering, days to maturity, number of primary branches per plant, number of secondary branches per plant, number of pods per plant, number of seeds per pod, showed positive significant correlation with seed yield both at phenotypic and genotypic level. Harvest index, days to maturity, 100-seed weight, number of primary branches per plant and pod length highest exerted positive direct effect on seed yield per plant.

Two hundred recombinant inbred lines of lentil derived from a cross IPL 98/193 (long root) × EC208362 (short root) was phenotyped in PVC tubes for root traits over two years. The observations were recorded after 60 days of sowing. Significant phenotypic variability for root and shoot traits under controlled conditions and for agronomic traits under normal sown conditions was observed in the present investigation among the RILs. The genotype and environment interactions were significant for all studied traits in the present investigation. No or poor association of root traits was observed with agronomic conditions in the present investigation. Bulk segregant analysis with SNP markers showed association of 15 SNP markers with root traits. Thus phenotypic variability present in the present RIL population can be used for identifying the QTLs for root traits and their use in breeding programs for the development of drought tolerant cultivars.

Milling of pigeonpea is an essential process to improve culinary properties. Byproducts obtained from the milling have many bioactive components which can have significant favorable effects on human health. In commercial mills, pigeonpea dal recovery is about 70% against the potential dal recovery of 85%. As the seed coat is tightly attached to the cotyledons due to the presence of a gum layer in between. During abrasive dehusking, a commonly adopted method in commercial mills, about 15% of protein-rich peripheral cotyledons get mixed with seed coat. The milling byproduct thus obtained includes pulse proteins in the form of broken, powder of cotyledons, and phenol and antioxidant rich husk. The present study focuses on biochemical estimation of pigeonpea whole, dehusked splits (dal), milling byproduct, and fractions of milling byproduct. The husk and the broken fraction of milling byproduct (about 75% of the byproduct) are rich in phenolic compounds, antioxidants, and dietary fiber, whereas the remaining cotyledon powder fraction is found to be rich in protein. These components were separated and analyzed for biochemical estimations. The results indicate that cotyledon powder separated from pigeonpea milling byproduct contains the highest protein (20.6%). Husk fraction of the byproduct is reported to have maximum total phenolic content (845.55 mg GAE/100g) and total antioxidant activity (59.68 m mole TE/100 g). Dehusked splits were observed to have the highest calorific value (386.17 kcal/100g). Till now, the milling byproduct is used as low-value cattle feed. Results of the biochemical studies reveal that protein, phenol and antioxidant-rich pigeonpea milling byproduct can be utilized for the development of value-added edible products and also find applications in therapeutic usage.
鸽豆的磨粉是提高烹饪性能的重要工艺。加工的副产品中含有许多生物活性成分，对人体健康有重要的有益作用。在商业工厂，木豆的回收率约为70%，而潜在的木豆回收率为85%。由于种皮与子叶之间存在一层树胶层，因此种皮与子叶紧密相连。在研磨脱壳过程中，大约15%富含蛋白质的外围子叶与种皮混合在一起。由此得到的碾磨副产物包括破碎形式的脉冲蛋白、子叶粉和富含酚和抗氧化剂的果皮。本文主要研究了鸽子豆的全粒、去皮的劈叶(木豆)、制粉副产物和制粉副产物馏分的生化评价。碾磨副产物的外壳和破碎部分(约占副产物的75%)富含酚类化合物、抗氧化剂和膳食纤维，而剩余的子叶粉末部分则富含蛋白质。这些成分被分离和分析用于生化评价。结果表明，鸽豆碾磨副产物子叶粉中蛋白质含量最高，为20.6%。据报道，副产物的壳部分具有最高的总酚含量(845.55 mg GAE/100g)和总抗氧化活性(59.68 m mol TE/ 100g)，脱壳裂片具有最高的热值(386.17 kcal/100g)。迄今为止，碾磨的副产品被用作低价值的牛饲料。生物化学研究结果表明，鸽豆碾磨副产物富含蛋白质、酚和抗氧化剂，可用于开发高附加值的食用产品，也可用于治疗。
