Parent Offspring Relations of Nutritional Quality Traits in 8 X 8 Partial Diallel Cross of Fresh Tomatoes.

Combining abilities for nutritional quality content were examined in tomato to understand the inheritance pattern of total soluble solids, titrable acidity, carbohydrates, proteins, carotenoids, ascorbic acid, potassium, lycopene and fruit yield plant-1. This experiment comprising a total of 64 treatments (28 F1+28 F2+ 8 parents) was evaluated in RBD. The results indicated that most of the traits were governed by additive gene action however non additive gene actionwas also important. The parent Pusa Ruby was found to be good general combiners for yield and nutritional traits and hence could be utilized in multiple breeding programs in future. The cross Pusa Ruby x Arka Vikas was desirable for fruit yield as well as nutritional characters since it inherited all nutritional traits except TSS content in F1generation and carotene content in F2 generation in desired direction.

Giardiasis--clinical and diagnostic perspective.

Fifty patients of chronic diarrhoea in the pediatric age group admitted in Kalawati Saran Children's Hospital were studied. Thirty cases were diagnosed to be suffering from giardiasis based on microscopy of fecal and/or duodenal fluid specimens. Fecal specimen microscopy missed two cases which were diagnosed by duodenal aspirate microscopy and vice-versa. All fecal specimens were negative on culture, while duodenal aspirate culture gave large number of false negative results. Serum immunoglobulin levels did not show significant changes. Thus, routine microscopic testing is presently the best means for early diagnosis of giardiasis.
