تقييم أداء تراكيب وراثية جديدة من الذرة البيضاء

الملخص EN

A field experiment was conducted at Field Crop Research Station of IPA — Agric.

Res.

Center during fall seasons of 2001 and 2002.

Thirteen genotypes including local cultivars (Anqad and Rabeh) were used in an RCBD with three replications.

Genotypes differed significantly in studied characters.

Number of days from sowing to 50% anthesis ranged between 63-92 days, plant height (78.5-219 cm), number of leaves/plant (8.6-14.1), panicale length (18.5-32.3 cm), number of branches/panicale (45-63), weight of 1000 kernel (25-39 2) and plant grain yield (42.6-146 g).

Significant positive correlation were obtained among grain yield of plant regarding panicale length, number of branches/panicle and kernel weight.

Genotype ISV.T5 gave longer panicle, higher number of branches/panicale, heavier weight of 1000 kernel and plant grain yield .Panicale length , number of branches/panicale and grain weight can be used as selection criteria to improve grain yield of sorghum.
