“…It is emerging as an important biouels feedstock. It produces about 30 kg per tree per year of seeds containing 55% oil (Biswas et al, 2013) This species has the potential of about 0. 2 M MT seeds, which can yield about 0.05 M MT, oil (Punia et al, 2006).…”

Twenty three CPTs (Candidate Plus Trees) of Pongamia pinnata were selected from different agro-climatic conditions of Haryana state of India and were assessed to identify the elite planting material for improvement of the species in terms of oil content. The differences among CPTs of P. pinnata were significant for seed oil content and all growth parameters of the progenies of these CPTs at the seedling stage. Oil content in P. pinnata varied from 27.07 (P12) to 38.17% (P2). The estimates of genotypic coefficients of variation for the characters studied were less as compared to the phenotypic coefficients of variation for all the characters examined. The highest phenotypic coefficient of variation (49.33) and genotypic coefficient of variation (28.56) was recorded for the germination percentage followed by height of the first branch. Number of leaves (0.5551**), inter-nodal length (0.5580**) and number of branches (0.6182**) showed high and positive correlation with the seed oil content. The progeny number 9, 21 and 2 were found to be the best on basis of oil content (36. 37, 36.83 and 38.17 %, respectively), and other characters examined. D 2 analysis grouped the CPTs into 5 clusters. The highest numbers of progenies were included in the cluster I followed by cluster III and least number of progenies i.e., two were observed in cluster II. The intra cluster distances ranged from 4.12 (cluster V) to 5.96 (cluster II). The maximum inter-cluster distance was observed between cluster II and III (10.02) followed by I and III and minimum was between clusters I and cluster V. The crosses between clusters II and III may result sufficient segregation for further improvement of the species. Therefore, the progenies belonging to the clusters II and III could be taken as parents for a successful hybridization program.

“…Some sugarcane varieties have been shown to display some biological nitrogen fixing activity through association with endophytic diazotrophic bacteria like Azospirillum and Azotobacter [48,49]. Thus nitrogenous fertiliser is the major energy input, as the Haber Bosch process is heavily based on fossil fuel for the required methane, heat and pressure [50].…”

With the ever-increasing population of the world (expected to reach 9.6 billion by 2050), and altered life style, comes an increased demand for food, fuel and fiber. However, scarcity of land, water and energy accompanied by climate change means that to produce enough to meet the demands is getting increasingly challenging. Today we must use every avenue from science and technology available to address these challenges. The natural process of symbiotic nitrogen fixation, whereby plants such as legumes fix atmospheric nitrogen gas to ammonia, usable by plants can have a substantial impact as it is found in nature, has low environmental and economic costs and is broadly established. Here we look at the importance of symbiotic nitrogen fixation in the production of biofuel feedstocks; how this process can address major challenges, how improving nitrogen fixation is essential, and what we can do about it.

“…The first article in this section from Biswas et al (2013) is a review article that highlights the importance of Pongamia pinnata as a candidate legume species for development as a feedstock for biodiesel and aviation fuel. The demand for food, fuel, and fiber continues to increase in parallel with an increasing world population.…”
