Advances in Heterocyclic Chemistry

Frozen French fries are the most popular processed potato product throughout the world. India lacks a suitable potato variety for French fry production. The variety Kufri Frysona has been developed to fill this gap to provide suitable raw material to French fry industry. Kufri Frysona gives tuber yields higher than the presently used Indian processing varieties Kufri Chipsona-1 and Kufri Surya. It also excels them in giving high proportion of oblong to long French fry grade tubers and better French fries in taste, texture and colour. Kufri Frysona possesses high field resistance to late blight disease and keeps well under country storage conditions for over 8 weeks.

Kufri Frysona: first high yielding potato variety for French fries in India.

The title compound, C30H20ClN3, is composed of a diaryl-substituted pyrazole ring connected to an aryl-substituted isoquinoline ring system with a dihedral angle of 65.1 (1)° between the pyrazole ring and the isoquinoline ring system. The 3-phenyl and 4-phenyl substitutents are twisted by 8.1 (1) and 43.0 (1)°, respectively, with respect to the pyrazole ring. The chloro­phenyl ring and the isoquinoline ring system are twisted by 21.2 (1)° with respect to each other.

1-[3-(4-Chloro-phen-yl)isoquinolin-1-yl]-3,5-diethyl-1H-pyrazole.

A total of 907 potato germplasm accessions along with four processing varieties (two indigenous and two exotic) stored in the cold store at 2-4 0C for 6 months were reconditioned for 7 days and evaluated for chip colour. None of the cultures produced acceptable chip colour (colour score up to 5). Fourteen accessions having chip colour score between 6-8 were further reconditioned for 21 days and re-evaluated for chip colour and certain processing related biochemical parameters. Two accessions, viz., Azul Soucco (Peru) and B 6561-4 (USA) produced acceptable chip colour of 4 and 5, with a dry matter content of 24.9 and 19.4% and reducing sugars content of 0.087 and 0.185% on fresh weight basis, respectively, as compared to the best control Frito Lay 1625 (score 7). The mean chip colour improved following reconditioning from 7 to 21 days, while a decline of 30 and 38% was observed in the mean contents of reducing sugars and free amino acids, respectively. Azul Soucco (Peru) was identified as the best accession for cold chipping and could be used for the development of indigenous cold chipping varieties. As regards, cold sweetening, except Dore (The Netherlands) and PSP 30-10 (Peru), the tubers of remaining 12 accessions and all the four processing varieties after 21 days of reconditioning contained lower levels of total sugars than the prescribed limit (>1.25% on fresh weight) which imparts sweet taste in table potatoes and can be used as parents for breeding table potato varieties with low or no sweetness.

The title compound, C25H19N3, is composed of an aryl-substituted pyrazole ring connected to an aryl-substituted isoquinoline ring system with a dihedral angle of 52.7 (1)° between the pyrazole ring and the isoquinoline ring system. The dihedral angle between the pyrazole ring and the phenyl ring attached to it is 27.4 (1)° and the dihedral angle between the isoquinoline ring system and the phenyl ring attached to it is 19.6 (1)°.

3-Methyl-5-phenyl-1-(3-phenylisoquinolin-1-yl)-1H-pyrazole

Pattern of chip colour distribution in the progenies of six crosses was studied in the first clonal generation at CPRS, Kufri. Chip colour distribution varied with cross combinations and frequency of getting excellent chip colour (score 1) was very low (1-5%) in these progenies. Clones with acceptable chips colour were obtained from both type of crosses i.e. good x good chipper and good x poor chipper, but the colour score was better in the latter. Cross combinations MP/97-583 x JEX/A-680-16, MP/97-628 x CP 2417 and MP/97-921 x CP 2132 produced higher percent (40%) of clones with lighter chip colour (< 3) and could be exploited for developing varieties for processing.
