Abstract

The alarming population growth rate in Pakistan has exacerbated the food security problem. The increase in the human population (3%) in the last two decades has nullified increased cereal production. The use of maize in the feed and wet milling industry is growing at a much larger pace than anticipated. Maize is being grown on an area of 1.016 million hectares with annual production of 3.037 million tons and an average grain yield of 2,864 kg/ha. Approximately 66% of the maize in Pakistan has access to irrigation; the remainder is farmed under strictly rain-fed conditions. Maize production in Pakistan has increased from 0.38 million tons during 1947-50 to 3.037 million tons in 2007. The trend is likely to continue at a much faster pace in the years to come. The adoption/cultivation of spring maize has increased, especially since the active involvement of multinationals in Pakistan. Today spring maize accounts for 12-15% of the total area and almost 30-35% of the total annual production. An annual increase of 20-25% in the maize area during spring has been observed, which is mainly because of very good yield levels (6-7 tons/ha). Spring maize is one of the success stories in Pakistani agriculture. Seed has been, and still is, the most important limiting factor in maize production in Pakistan. Only 34% improved seed is available. The markets are not stable and have uncertainty due to the lack of drying and grain storage facilities. The use of maize grain in poultry feed is on the increase in Punjab province up from 23% in 2001 to 55% in 2007.

Abstract

Several experiments were carried out to establish an efficient regenerating protocol for cultivated eggplant varieties. Among the five varieties cultured on Murashige and Skoog (MS) medium with free plant growth regulator (PGR), Nayantara performed better considering the number of shoots/explant (2.48). Considering explant types and culture conditions, better performance was observed (3.68 shoots/ explant) when seed germination in the dark was proceeded by bottom hypocotyl segments cultured under dark conditions. A higher rate of shoot regeneration was observed in Nayantara when cultured in Zeatin Riboside (ZR) and Thidizuron (TDZ) supplemented MS medium. The highest number of shoots per explant was produced on MS medium supplemented with 2.0 mg/L ZR and 0.1 mg/L indole acetic acid (6.65 shoots/explant). Proliferation and elongation of the regenerated shoots were obtained in the MS medium with free PGR. The best rooting performance was observed in MS medium supplemented with 2.0 mg/L indole butyric acid. Plantlets with well developed roots and shoots were successfully transferred to soil.
