Performance of fullsib families in different maize varieties for morphological characters

The present research was carried out at the experimental plots of Agricultural Research Station, Seen Lasht, Chitral-Pakistan. Eight, thirty and twenty fullsibs progenies in three different maize varieties was laid out in Randomized Complete Block Design (RCBD) with replicate thrice in three rows of three meter length. Analysis of variance showed that Azam was highly significant for days to anthesis, days to silking and grain yield. Similarly, Pahari and Iqbal showed highly significant difference for days to anthesis, days to silking, days to maturity and grain yield. Minimum (57 days, 59 days, 2 days and 94 days) days to anthesis, days to silking, anthesis to silking interval (ASI) and days to maturity was recorded by Azam-3, Azam-5, Azam-1 and Azam-4 while maximum (4.3700Kg/plot) grain yield was recorded by Azam-6. Lowest days to anthesis (57 days), days to silking (60 days), anthesis to silking interval (ASI) (2 days) and days to maturity (93 days) was recorded by Pahari-4, Pahari-3, Pahari-1 and Pahari-27 while highest (4.84Kg/plot) was showed by Pahari-14. Days to anthesis, days to silking, anthesis to silking interval (ASI), days to maturity and grain yield of Iqbal-8 (57 days), Iqbal-2 (60 days), Iqbal-2 (2 days) and Iqbal-1 (94 days) was observed low values while Iqbal-17 observed high (3.1713 kg/plot) values for grain yield. Correlation of Azam showed that days to silking with days to anthesis; days to maturity with days to anthesis and days to silking observed highly significant while days to maturity with anthesis to silking interval (ASI) observed significant difference. Correlations of Pahari showed that days to silking with days to anthesis; days to maturity with days to anthesis and days to silking; grain yield with days to maturity observed highly significant but grain yield with days to anthesis and days to silking observed significant difference. Correlation analysis of Iqbal showed that days to silking with days to anthesis; days to maturity with days to anthesis and days to silking showed highly significant while anthesis to silking interval (ASI) with days to silking and days to maturity with anthesis to silking interval (ASI) observed significant difference. This was concluded that Azam shall be included in future maize breeding program because of their short duration between days to silking and days to maturity.
