RESULTS AND DISCUSSION
The Inbred parents and hybrids under study are rich in protein (8.08 to 11.34%), starch (59.78 to 71.88%) and oil (3.30 to 4.59%) and popping expansion was also observed very good up to 28.4 cc/g. Among the parents, I-07-63-36-1 showed good popping expansion of 25.4 cc/g also having good amount of protein (10.02%), starch (64.91%) and oil (3.97%). In case of hybrid, I-07-63-1-2 x I-07-63-36-1 showed high popping expansion of 28.2 cc/g with enhance amount of protein (10.54%), starch (64.89%) and oil (4.03%). The cross, I-07-43-7-3 x I-07-35-7-3 possessed highest oil content of 4.59%. The per se performance of parents and selected hybrids is presented in Table 1.
The analysis of variance for all the traits studied was highly significant, indicating the existence of sufficient variation in the material studied. The ANOVA of diallel mating showed highly significant estimates of both GCA and SCA for all traits. The quadratic components associated with the SCA effect were greater than GCA for all traits evaluated, which revealed preponderance of non-additive gene action for inheritance (Table 2). Similar results of predominance role of non-additive gene action of traits were corresponded for grain yield per plant, protein, starch and oil content in normal maize (3); for days to flowering and maturity, plant height, grain yield and popping expansion (22); for grain yield and popping expansion (18); for plant height, grain yield per plant and popping expansion (9, 10).
For exploiting hybrid vigour, per se performance, the extent of heterosis and SCA effects of hybrids are important tools. The heterosis value with their magnitude and significance of selected hybrids is presented in Table 3. The selection of hybrids ...

Evidence has shown that the corn we know today is quite different from the first time it was domesticated in Mexico. Although researchers and the academic world acknowledge that corn began its world journey in Mexico, they are unsure as to the time and location of the earliest domestication (American Society of Plant Biologist). Through genetics, teosinte is found to be corn’s wild ancestor. Although the two do not look much alike, at a DNA level they are surprisingly alike, such as having the same number of chromosomes and a remarkably similar arrangement of genes (The University of Utah).

Flax/linseed (Linum usitatissimum L.) is one of the oldest cultivated plants grown for food, industrial and medicinal value. It is commonly known as Alsi. Flaxseed is an important crop of genus Linum belongs to the family linaceae. During 2013, the total global linseed area was 2270.35 thousand hectare and production was 2238.94 thousand tons with average productivity of 936.16 kg/ha (Anonymous, 2013). In India, linseed is one of the most important industrial oilseed crop and stands next to rapeseed and mustard in terms of area and production. In India it is cultivated in an area of 338 thousand hectares with production and productivity of 147 thousand tons and 434.91 kg/ha, respectively (Anonymous, 2013). The most frequent seed colours in

Azadi and Ho (2010) highlighted that the productivity in different fields includes agriculture can be improved by developing their technological strategies. Living modified organisms (LMO) or known as genetically modified (GM) is one new technical method that can be used to develop new crop varieties through genetic engineering technique which will provide potential contributions to sustainable agricultural productivity and also new inputs for resource-poor and small scale farmers. According to Kruff (2001), GM seeds defined as seeds that have been modified to contain specific characteristics such as he...
