Breeding for improved organoleptic and nutritionally acceptable green maize varieties by crossing sweet corn (Zea mays saccharata): Changes in quantitative and qualitative characteristics in F1 hybrids and F2 populations

    Reports of improvement in sweet corn (Zea mays saccharata) for grain yield and agronomic traits through introgression of genes from the field corn (Zea mays L.) are common in literature. However, few studies have reported improvement in field corn varieties for organoleptic and/or nutritional properties through the transfer of recessive alleles that condition sweetness in...

Optimization and development of regeneration and transformation protocol in Indian mustard using lectin gene from chickpea [Cicer arietinum (L.)]

  A simple and easy protocol for regeneration and genetic transformation ofBrassica juncea (L.) Czern and Coss cv. Pusa bold has been developed. The optimum regeneration was found on combination of BAP (3.0 mg/l) and IAA (0.2 mg/l). The genetic transformation protocol has been standardized usingAgrobacterium tumefaciens (gv3101). Cotyledonary petioles used as explant were pre-cultured for 48 h...

Line x tester analysis across locations and years in Sudanese x exotic lines of forage sorghum

  Combining ability in forage sorghum [Sorghum bicolor (L.) Moench] was not as much investigated as in grain sorghum. In the present study, 4 local stocks (Testers) and 7 exotic stocks in A3 cytoplasm were crossed in line x tester fashion to investigate combining ability in forage sorghum. The hybrids and their parents were evaluated across two years (2002 - 2003) and at two locations in Khartoum...
