Inheritance of some morphological characters in chickpea (Cicer arietinum L.)

The present investigation was undertaken to generate information on the inheritance of flower colour, leaflet size and pigmented stem in chickpea (Cicer arietinum L.). Parents, F1’s, and F2’s of crosses Vijay x PKV-4, Digvijay x PKV-4 and BDNG-797 x PKV-4 were evaluated during rabi, 2018-19. The monogenic inheritance was confirmed for two traits, pink vs. white flower colour and pigmented vs. non pigmented stem pigmentation. Leaflet size, small vs. broad was controlled by duplicate gene action. The genetic inheritance of these morphological traits is essential for the selection of superior and desirable transgressive segregants for the genetic improvement of the crop. These results are of essential significance because these traits are used as visual markers in chickpea breeding for early recognition of the hybrid nature of plants

Synthesis and characterization of molecules containing thiazole and oxazole moieties and study of ESIPT phenomenon

Two novel ESIPT molecules, 2-[4-(1,3-benzothiazol-2-yl)naphtho[1,2-d][1,3] oxazol-2-yl]phenol 9a and 4-[4-(1,3-benzothiazol-2-yl)naphtho[1,2-d][1,3]oxazol- 2-yl]benzene-1,3-diol 9b were synthesized by condensing 1-amino-3-(1,3- benzothiazol-2-yl)naphthalen-2-ol with 2-hydroxybenzoic acid and 2,4-dihydroxybenzoic acid respectively. The novel compounds were characterized by FT-IR, ¹H NMR, Mass spectral and elemental analysis. Effect of polarity on photo physical properties, absorption and emission were studied. Compounds showed single absorption and dual emission due to ESIPT phenomenon. The structural changes due to ESIPT phenomenon in terms of bond angle, bond distances and geometry were investigated by using Gaussian 03 software. These two novel ESIPT molecules are thermally stable up to 200 °C.12 page(s
