In order to explore the breeding potential and variability for the evaluation of new better performing, high yielding varieties with good adaptability, heritability and genetic advance were estimated for the following seven cross of F2 population viz., DN 52 x Fareed 2006, DN52 x Sehar 2006, DN 53 x Chakwal 86, DN 53 x Fareed 2006, DN 57 x Chakwal 86, DN 53 x Sehar 2006, DN 57 x Sehar 2006. Heritability and genetic advance were was determine for the following characters plant height, flag leaf area, number of tillers per plant, spike length, number of spikelet's per spike, spike density, number of grains per spike, 1000-grain weight and grain yield per plant.

Wheat is the most important cereal crop used directly as human consumable commodity by the major portion of world's population. An adequate staple food supply is the first pre-requisite in any country for social and economic stability. Wheat is the most important grain and a staple food for more than one third of the world's population. Large number of products and by products are obtained from this king of cereals. F2 populations of seven cross combinations Lasani-2008 x Iqbal-2000, Lasani-2008 x 9432, Lasani-2008 x 9436, Lasani-2008 x 9444, Iqbal-2000 x Lasani-2008, Iqbal-2000 x 9432 and Iqbal-2000 x 9436 involving cultivars/ lines Lasani-2008, Iqbal-2000, 9432, 9436 and 9444 were studied to determine the heritability and expected genetic advance in order to explore and utilize the hidden genetic potential so that new high yielding and better adapted cultivars can be developed in order cope with the rapidly changing environment and global demand of food with minimum inputs."

Vegetable fats and oils are lipid materials derived from plants. Physically, oils are liquid at room temperature, and fats are solid. Chemically, both fats and oils are composed of triglycerides, as contrasted with waxes which lack glycerin in their structure. Although many plant parts may yield oil, in commercial practice, oil is extracted primarily from seeds. The melting temperature distinction between oils and fats is imprecise, since definitions of room temperature vary, and typically natural oils have a melting range instead of a single melting point since natural oils are not chemically homogeneous. Although thought of as esters of glycerin and a varying blend of fatty acids, fats and oils also typically contain free fatty acids, monoglycerides and diglycerides, and unsaponifiable lipids. Vegetable fats and oils may or may not be edible. Examples of inedible vegetable fats and oils include processed linseed oil, tung oil, and castor oil used in lubricants, paints, cosmetics, pharmaceuticals, and other industrial purposes.

Bread wheat (Triticum aestivum L.) is a major food crop in the world and a staple food of Pakistan which plays a remarkable role in meeting the food requirements of the country.Worldwide wheat provides nearly 55% of the carbohydrates and 20 % of the food calories consumed globally. Most of the wheat is growing for human consumption and about 10 % is retained for seed and industry. On the world basis it ranks after rice providing chief protein and caloric requirements for one third of the world population and is consumed in a variety of ways.At present though the production of wheat is increasing gradually but yield is still trailing the average obtained in similar ecologies elsewhere. A significant yield improvement is still possible through the development of high yielding varieties that are adaptable to various agro-climatic conditions. Manipulation of accessions for exploring genotypes with best combining ability and identification of transgrassive segregates by using modern genetic tools is prerequisite for high yielding varieties. Current studies on combining ability and authentication of F1 hybrids provided excellent results in this regard.
