An efficient delivery system for seed-protectant chemicals is needed in light of several disadvantages of conventional seed treatment methods. This study evaluates the efficacy of film-coat application in maintaining the persistence and potency of imidacloprid on Lycopersicon esculentum (L.) Mill. seeds after simultaneous storage under ambient and regulated environment in paper and aluminium packages. High-performance liquid chromatography (HPLC) revealed 0.135 mg kg−1 of herbage material to be the threshold value beyond which absolute control was obtained, and with film coating the latter was achieved even with half-dosage seed treatment, irrespective of the storage condition. The technique provided early protection to the crop and also nullified the...

Genetic segregation patterns were observed for awning in 4 generations of the crosses of Jawahar New plant Type (JNPT): 'JNPT 63-01 ' x 'Pusa Basrnati 1' and 'JNPT 89' x 'Pusa Basrnati 1' in parental, F,, F, and F, generations. The observations clearly indicate that awn character in 'Pusa Basrnati 1' is governed by a dominant gene and presence of awn to be dominant over its absence.

A study was conducted during rainy (kharif) season of 2004 and 2005 in a sandy loam soil of the semi-arid region of Delhi to study the effect of different doses of nitrogen (30, 60 and 120 kg/ha) under rainfed and irrigated condition on ‘HHB 67’ pearl millet [Pennisetum glaucum (L.) R.Br. emend. stuntz.]. Growth rate varied between different seasonal weather condition, but the relative growth rate and the partitioning of dry matter was similar. Yields were more influenced by water application than the nitrogen doses. Maximum yield (3.19 and 3.10 tonnes/ha in 2004 and 2005, respectively) was recorded with 120 kg N/ha application under irrigated condition, while optimum yield (2.30 and 2.40 tonnes/ha in 2004 and 2005, respectively) and water-use efficiency...

Production of hydroperoxides and volatile aldehydes, having low olfactory thresholds by lipoxygenase (LOX) action, is an important problem in the effective use of soybeans as food ingredients. In this study, researchers examined sixteen soybean varieties forLOXactivity, thiobarbituric acid (TBA) number, a measure of lipid peroxides, and carbonyl value, an index of ketone compounds, responsible for off-flavor. Among the soybeans tested, PK416 and JS7015 had the lowest levels of LOX activity, TBA number as well as carbonyl value. The highest value for these parameters were observed in Pb-1 and Bragg. These results suggest that PK416 and JS7015 could be excellent soybean sources for making good quality soy products. Tipo: Article Palavras-chave: Agricultural Sciences and Technology; Biochemistry.

The inherent complexity of yield and its environmental effects are the main constraints to yield improvement. An easier approach would be to improve the component traits that finally manifest into higher yield gains. Though a lot of literature has been generated in rice (Oryza sativa L.) on the type of gene actions, the success of breeding programmes in new plant types (NPTs) for yield has been hampered by lack of meaningful knowledge on the inheritance of yield components and yield contributing traits. Genes governing the character expressions in such altered genotypes were described. The F2 frequency distribution showed continuous variation indicating the polygenic nature of inheritance of these traits. In general, it was observed that dominant gene...

The in vitro performance of mango shoot culture is delimited by several factors, of which explant necrosis and media browning are considered as major constraints for successful exploitation of such an important commercial crop. Our results showed that source of explants had a significant effect on the performance of in vitro cultures of mango. The variations in survival of explants collected from glasshouse grown seedlings and field-grown stock plants indicated towards differences between their physiological/ ontogenic age. Though, chronologically, both are young, the glasshouse grown shoots are ontogenetically younger and; therefore, responded better over field-grown shoots. Improved performance of explants harvested from mycorrhizal plants suggests...

BGD 112’ and ‘FLIP 90–166’ using Sequence-tagged Microsatellite (STMS) Markers. Both the parents representing the cultivated chickpea, the map loci marked indicates usable polymorphism for genetic as well as loci studies. A total of 250 STMS markers were used to study the parental polymorphism and 49 of which had showed polymorphism were used for genotyping F2 lines. Linkage analysis revealed 8 linkage groups mapped by 33 loci by these markers covering a distance of 471.1 cM of map distance with an average marker density of 14.2 cM at a LOD of 3.0. The molecular map using desi × kabuli cross throws insights into variability and diversity that can be utilized directly by the breeders unlike that generated using wide crosses as the loci that this map has...

It is still growing and the new developments are accumulating at an unprecedented rate. Its core principles have been effectively utilized for genetic improvement of the crop species resulting in increased harvest with good quality. However, to meet the increasing demand for food crops, it becomes imperative for interdisciplinary approaches where genetics and plant breeding shall play the key role. With the recent advances in biotechnology, information technology, software-assisted quantitative genetics, crop modeling, etc. have opened new vistas for genetic dissection of complex traits of economic importance in crop plants. Similarly, the information... Tipo: Book Palavras-chave: Agricultural Sciences and Technology; Biotechnology.

Realizing the importance of agriculture to the Indian economy and in accelerat- ing the process of development, a special section of the Current Science1 was re- cently brought out on the application of plant biotechnology in crop improve- ment. The reviewers have made several useful observations explaining the insti- tutional framework and codal proce- dures, review of the progress, indexing the plant breeder’s perceptions on the is- sues to be tackled, advances in the engi- neering of host plant resistance, the awaited improvements in the plant vari- ety act, and positioning India in the context of the ongoing global R&D envi- ronment.

In this paper, we have used rule-based approach to predict mature miRNA from pre-miRNAs of Bombyx moori (Silk worm). For rule based approach, it is important to have a set of rules. Unfortunately, to the best of our knowledge, miRNA related literature does not provide well-defined set of rules for miRNA prediction. Therefore, the challenge in this research was to derive a set of rules from known data set of related species. We have made an attempt to derive a set of rules from the known miRNA and pre-miRNA data sets of Drosophila melanogaster and Apis mellifera. The derivation of rules is based on the dominating features identified using PCA and infogain method applied by authors in their previous work. Based on these rule set a PERL script is written to...

Quality protein maize (QPM) originally developed in the late 1990s at CIMMYT, Mexico possesses roughly twice as much usable protein as normal maize grown in the tropics. The improved quality of the protein in QPM is due to enhancement in lysine and tryptophan – the two limiting amino acids that are known to be regulated by opaque2 gene and associated modifiers. QPM has widely been adopted for cultivation in the developing world to fight protein malnutrition. India, QPM was released for commercial cultivation almost a decade ago by introducing QPM lines from CIMMYT. However, all these inbred lines are of longer duration and thus, give rise to QPM hybrids of full season maturity. Utilizing marker assisted selection we transferred opaque2, a...
