Monoploid Frequencies in a Commercial Double Cross Hybrid Maize, and in Its Component Single Cross Hybrids and Inbred Lines.
ARTHENOGENETIC development of the egg in maize under the stimuP lus of pollination and normal endosperm development has been noted by RANDOLPH (1939), STADLER (1949), FORTUNO (1948) and others. Data on the frequency of haploidy are meager. RANDOLPH discovered 23 parthenogenetic diploids among 17,165 individuals in the progeny of tetraploid maize, a frequency of about 1:’750. EINSET (1942) found...

This study was conducted to evaluate the responses of Iranian commercial genotypes of maize (hybrids and their inbred lines) to callus induction and plant regeneration, using mature embryos. Twenty five genotypes comprising of 12 inbred lines, 11 single cross hybrids, 1 double cross hybrid and 1 composite cultivar were used. Mature embryos of the genotypes were plated on MS and N6 media. Callus...

چکیده حیطه ی نوشتار دانشگاهی اخیرا شاهد تغییرات عمده ای از غیرشخصی بودن (عینی بودن) به شخصی بودن بوده است. شخصی بودن متون دانشگاهی اهمیت استفاده از وجهیت معرفتی را برجسته می سازد چرا که? وجهیت معرفتی? بر اساس یکی از تعاریف ارائه شده از این مقوله? ارتباط تنگاتنگی با شخصی بودن داشته و به عنوان بیان نظر شخصی گوینده در مورد جز گزاره ای گفته در نظر گرفته میشود. بنابراین? با در نظر داشتن نقاط مشترک...
15 صفحه اولGenetic distance estimates among single cross hybrids and correlation with specific combining ability and yield in corn double cross hybrids.
The objective of the present study was to correlate the genetic distances (GD) of single cross hybrids with yield, heterosis and specific combining ability (SCA) in the double cross hybrid synthesis. For this, 10 single cross commercial hybrids were used from different companies, and all the possible double hybrids were synthesized by a complete dialell. The hybrids were assessed in 15 location...
