VL Mandua 382: The first early maturing, white seeded finger millet cultivar suitable for rainfed organic agro-ecology of Himalayan region

The normal light intensity during monsoon season in rainfed finger millet cultivation regions in particular, Bangalore, is around 1200 uMm-2s-1; the effect of reduction in light intensity on physiological parameters and grain yield of finger millet was studied. The experiment was laid out in split plot design with four light intensity treatments and three varieties in three replications. Each replication had four lines of 1.5 m row length (1.5 m x 1.0 m). The crop was directly sown on 03-08-2007 with the spacing of 22.5 cm between rows and 10 cm between the hills, using three varieties namely, GPU-48 (early maturing variety, 100 days), GPU-28 (medium maturing variety, 110 days), and L-5 (late maturing variety, 120 days). Decreased light intensity at canopy level decreased the leaf area, specific leaf weight, net assimilation rate and biomass production, which resulted in decreased grain yield in all varieties. Mean grain yield decreased by 16.4, 34.7 and 55.7% respectively with 75, 50 and 25% light intensity. Low light intensity decreased the biomass, which is important in regional fodder security. Early maturing variety had lesser percent reduction in grain yield (1.68%) as compared to the medium (9.5%) and late maturing (29.0%) varieties at low light intensity of 75 % natural light. Therefore, the critical lower limit of light intensity could be nearly 1200 uMm-2s-1 for finger millet potential yield. The results obtained in this study also suggests that genotypic variability for low light adaptation of early maturing genotype (GPU-48) can be exploited for intercropping systems in rainfed mango plantations up to 4-5 years.

Abstract Round the globe, availability of the germplasm of suitable crops for cultivation in remote, inaccessible and resource poor terrains is crucial for food security in these regions. Rich diversity of millets, which are highly tolerant to extreme weather conditions, is available in the Central Himalayan Region (CHR). However, biochemical evaluation of available germplasm for food security is a major issue yet to be addressed properly. In this backdrop plant exploration and germplasm collection expeditions were conducted to collect and evaluate the genetic diversity of finger millet (Fig. 1). A total of 314 accessions having traits of agronomic importance were collected and evaluated for three consecutive years. In addition to battery of biochemical traits, yield was recorded to find out suitable germplasm for large scale cultivation/ breeding programme. At flowering stage variability in antioxidants level of leaves such as glutathione and ascorbate ranged from 105.27 – 423.63 mmol.g-1FW and 4.89 – 10.21 mmol.g-1FW respectively. Extensive variability in the activity of enzymes important for multiple abiotic stress tolerance viz., catalase (115 – 855 mmol hydrogen peroxide decomposed.min-1.mg-1 protein), peroxidase (1.24 - 6.35 mmol substrate.min.-1.mg-1 protein), superoxide dismutase (1236 – 2963 enzyme U.mg-1 protein), glutathione reductase (0.53 – 2.14 mmol substrate.min-1.mg-1 protein), ascorbate peroxidase (1.86 – 7.04 mmol substrate.min-1.mg-1 protein), monodehydroascorbate reducatase (1.11 – 4.41 mmol substrate.min-1.mg-1 protein), dehydroascorbate reducatase (0.34 – 1.36 mmol substrate.min-1.mg-1 protein) was also recorded. Worldwide Abiotic/ environmental stresses hamper agricultural production. Enzymatic and non-enzymatic defence system precisely controls this situation. Hence, biochemical evaluation might be an appropriate strategy for identification of suitable germplam to combat the problem of food security in such areas.

This article reports the occurrence of the thalloid liverwort Cyathodium denticulatum Udar et Srivastava was collected first time from the Achanakmar – Amarkantak Biosphere Reserve (AABR) Bilaspur, Chhattisgarh. It is shown that Cyathodium denticulatum a narrow Himalayan endemic has been reported earlier from Darjeeling, India. There is no record of its occurrence from central India. Cyathodium denticulatum is a rare species known only from eastern Himalayan region. A key to related Indian taxa and taxonomic description is provided.
