PRODUCING SUPERIOR HYBRIDS OF SWEET PEPPER CROP (Capsicum annuum L.) IN NORTH SINAI
Mahmoud Ibrahim Mahmoud Ibrahim;
Abstract
The study was carried out at the Experimental Farm, Faculty of
Environmental Agricultural Sciences, El-Arish, Suez Canal University during
1999 to 2002 to produce new promising hybrids of sweet pepper suitable to North Sinai region, and to determine some useful genetic parameters of sweet pepper.
The study included six cultivars of sweet pepper introduced from different
geographical regions used to produce 15 hybrids,which were all possible hybrids between them in one way, and F2 populations of these parents.
The six parents, Ft and F2 populations and the Majester Fl (check hybrid) were evaluated in 2001/2002 under the protected cultivation in plastic houses in a randomized complete block design with four replications for vegetative characters, earliness, early yield, total yield ,and fruit characteristics
The obtained results cleared that the overall mean ofF1 means surpassed parents and the check hybrid in most studied characters. Heterosis over mid parents was • significant or highly significant with positive values. Average heterosis over the better parent was none significant or had negative values for most traits. Average heterosis over the check hybrid was highly significant with positive values for many traits.
Inbreeding depression was found for many traits. Both general and specific combining ability were highly significant for most studied traits. Sweet Chinese cultivar had a high combining ability for many traits as well as California Wonder cultivar.
Heritability estimates m broad sense ranged from moderate to high for different traits. Additive variance represented a large amount of total variance. Correlation among the studied traits cleared high positive or negative correlation between many traits.
