Variability in total phenolic content of pearl millet genotypes: inbreds and designated B-lines

Total phenols of the 90 pearl millet genotypes comprising 46 each of inbreds and designated B-lines (maintainer of CMS lines) grown during kharif-2013 was estimated and those of the 27 genotypes (9 inbreds and 18 designated B-lines) selected during kharif-2013 further grown during kharif-2014 and estimated total phenolic content. Across the groups, pearl millet genotypes showed a significant and marked variation during both the seasons. It varied from rom 175 to 435 mg catechol equi./100g during kharif-2013 and from 191 to 387 mg catechol equi./100g dring kharif 2014. The mean total phenolic content of two seasons (kharif-2013 and kharif-2014) of selected lines varied from 199 to 400 mg catechol equi./100g. During both the seasons designated B lines showed lower mean total phenolic content than that of inbred lines. On the basis of mean performance during kharif-2013 and kharif-2014 HTP 94/54, LPBL 10/112, HMS 14B and HMS 21B were identified as low total phenols containing lines whereas, DPHBL-11-123, HBL 112/H12/1011, HMS 36B and HMS 53B were identified as high phenolic containing pearl millet lines

Horticulture based crop production site management approach (HBCPSMA): an innovative concept for doubling farm income under dry-lands

Most of the recent past advances in Indian horticulture are for production with favorable agro-climate. The vast land and diverse areas of Rajasthan (desertic hot arid, semi-arid to sub-humid and tribal zone) is yet not received systematic thought for horticulture development. What is needed is intensive surveys and analysis of these vast and varied areas for their potentiality which they offer for the production of large number of fruits, vegetables, seed spices and high value crop-plants and their agro-climatologically settings for the particular crop and commodity based land and resource use, and strategies for the development of production sites and related systems (crops for truck gardening, seed production, organic culture, external and export market, rural industries and storage and marketing chain) for the defined sub-zones. Secondly, some of the existing production system should be modified and converted in to the clusters of villages or area based production sites adopting industrial approaches, and for this regional institutes, stations and KVK’s should be given mandate for commodity based zonal production site intensive research and development of cultivation areas. Similarly, large-scale varietal trials on adaptive and new crops and their genotypes should be organized followed by regular supply of quality seed / planting material by specialized organization in region for stability in targeted commodity cultivation on commercial scale and development of chain for storage and marketing. At the same time, crop-commodity groups consisted of producers, research and extension services and developmental agencies be developed and recognized in each production sites (HBCPSMA) as system approach

Quality of guava products (squash, RTS and jam) prepared from preserved

This study was carried out to utilize the preserved guava pulp for preparing squash, RTS and jam and evaluate its quality (at 3 months). For this the pulp of two guava varieties (L-49 and Lalit) preserved with nine different treatments viz., potassium meta bi-sulphite 0.1% (T1), sodium benzoate 0.1% (T2), potassium meta bi-sulphite + sodium benzoate 0.05% each, sodium benzoate + potassium sorbate 0.05% (T4), potassium meta bi-sulphite + potassium sorbate 0.05% each (T5), potassium sorbate 0.025% (T6), potassium sorbate 0.05% (T7), potassium sorbate 0.1% (T8) and frozen storage -200 C (T9) and replicated four times with two experimental sets under Factorial CRD. The results revealed that at the end of storage (90 days) analyzed good qualitative characters TSS, acidity, sugars, ascorbic acid, pH by in low temperature storage (-20 0C) followed by addition of potassium meta bi-sulphite 0.1% and sodium benzoate + potassium meta bi-sulphite 0.05% each. Prepared squash, RTS and jam from preserved guava pulp also have good quality
