(Texas A&M University. Libraries, 1986)In some Central American countries, sorghum totally or partially replaces maize in the tortilla making process. Maize is preferred over sorghum despite sorghum yield advantage. The major constraint to increasing sorghum ...
-
(Texas A&M University. Libraries, 1969)Four cotton strains (Gossypium hirsutum L.), their reciprocal F₁, F₂ and backcross hybrids supplied the seedcotton for estimations of lint percentage and separation into five different components as follows: (1 ) embryos ...
-
(Texas A&M University. Libraries, 1977)Three coverted lines (SC0056, SC00599, and SC0170) from the sorghum conbersion program remained green and vigorous in the field at grain harvest time when "normal" sorghum types senesced and apparently ceased functioning ...
-
(Texas A&M University. Libraries, 1985)Inbred lines, F1 crosses and progeny from F2 populations were utilized to determine if the primary loci which control pericarp color (R, Y, B1, B2 and S) affected tannin presence and concentration differently when they ...
-
(Texas A&M University. Libraries, 1994)Rose clover (Trifolium hirtum All.) is a winter annual legume with potential for increased use as a forage crop in Texas, Oklahoma and the U.S. southern region. There is a need for rose clover cultivars are needed with ...
-
Cold tolerance of sorghum [Sorghum bicolor (L.) Moench] during germination and early seedling growth (Texas A&M University. Libraries, 1985)Both laboratory and field experiments were conducted to investigate the level of cold tolerance in early seedling stages of 5 sorghum lines originating from China (kaoliang), 5 temperately (TE) and 5 tropically (TA) adapted ...
-
(Texas A&M University. Libraries, 1985)New elite inbred lines derived from crosses involving genetic material from the Sorghum Conversion Program were evaluated for combining ability and agronomic performance at four diverse locations across Texas. Entries were ...
-
(Texas A&M University. Libraries, 1979)Percent infection and gain per cycle of selection were compared after two cycles of mass selection with progeny test, mass selection without progeny test and S1 selection in breeding for resistance to sorghum downy mildew ...
-
(Texas A&M University. Libraries, 1967)A study was conducted to compare and correlate the performance of parents and hybrids in early and late generations of grain sorghum and to evaluate the combining abilities of selections and four male-sterile lines. A cross ...
-
(Texas A&M University. Libraries, 1986)Parameters affecting couscous quality were evaluated. Considering sorghum and millets, significant differences were found for milling ability, product color and chemical analysis. Millet products exhibited a higher degree ...
-
(Texas A&M University. Libraries, 1970)The nature of sterility in four lines of rice, G2254 (an off type found in a field of the standard rice variety Belle Patna), G2250 (a rogue from a field of fertile rice), G2266 (obtained by hybridization between the ...
-
(Texas A&M University. Libraries, 1971)The cytotaxonomic investigation of various species in the Cenchrus-Pennisetum Complex was conducted to provide information for taxonomic classification and as a basis for a breeding program. These species (x = 9) are similar ...
-
(Texas A&M University. Libraries, 1968)The experiments herein reported were conducted at College Station, Chillicothe and McGregor, Texas, with the objectives of determining the relationships of varying seed sizes and shapes in wheat to yield, yield components, ...
-
(Texas A&M University. Libraries, 1986)Several maize genotypes were grown in College Station and Etter, Texas in 1983 and College Station in 1984. Irrigations were scheduled to provide full and limited irrigation plots at each site. Each genotype was also ...
-
(Texas A&M University. Libraries, 1970)This study was undertaken to evaluate the genetic variance and the genetic behavior of each of twelve corn composites developed in a reciprocal recurrent selection program. The seed sources used for this study were obtained ...
-
(Texas A&M University. Libraries, 1974)The objectives of this study were: (i) to evaluate combining ability of segregates from different backcross cycles of exotic sorghums conversion program, and (ii) to determine whether there are changes in combining ability ...
-
(Texas A&M University. Libraries, 1973)This study was designed to determine if the reciprocal recurrent selection program at the Texas Agricultural Experiment Station at Texas A&M University has improved the probability of selecting a higher frequency of ...
-
(Texas A&M University. Libraries, 1969)A complete diallel cross consisting of all possible F₁ hybrid combinations among 9 selected cotton varieties and their corresponding F₂'s were studied using a split-plot design with four replications. Data were taken on ...
-
(Texas A&M University. Libraries, 1969)Genetic behavior and the relationships of quantitative and qualitative characters were studied using five United States rice varieties and the F2 and F3 generations of six of their crosses. Biometrical data indicated that ...
-
(Texas A&M University. Libraries, 1985)Twelve cotton lines with different seed-oil contents, six glanded and six glandless, were crossed in a full diallel mating system. All progenies were evaluated for seed-oil percentage (SO), seed index (SI, mg/seed), and ...
