    EVALUATION OF MORPHOLOGICAL PARAMETERS OFSIX UPLAND NIGERIA COTTON(GOSSYPIUM HIRSUTUML.)GENOTYPES

    This study was carried out to access the variation in morphological and yield parameters among six Nigeria cotton genotypes. A total of six genotypes of cotton; Samcot 8, Samcot 9, Samcot 10 Samcot 11, Samcot 12, and Samcot 13 were evaluated for plant height, number of branches, number of bolls per plant and boll size. Seeds of the six genotypes were raised to maturity in a Complete Randomized Design (CRD) with five replicates and data were collected following standard procedures. Data collected were subjected to one-way analysis of variance (ANOVA) and results were considered significant at a significance level of 5 %. Results obtained showed significant variations in plant height with Samcot 13 having the highest plant height (106.10 ± 3.83cm) followed by Samcot 9 (103.00± 2.39 cm). The highest monopodialbranch was observed inSamcot 8 (21.40 ± 0.87) while the highest sympodialbranch was observed in Samcot 11 16.40 ± 0.86). Significant variations were observed in the number of bolls per plant and boll size with Samcot 9 having the highest number of bolls (31.30 ± 3.23) while the least was recorded in Samcot 12 (19.30 ± 3.03). Samcot 8 had the highest boll size (11.25 ± 0.25 cm) while Samcot 11 had the least boll size (9.60 ± 0.28 cm). Yield and yield attributes varied significantly, with different traits been favored by different genotypes. Samcot 9 had the highest weight of bolls (32.17 ± 5.49 g) while the least was observed in Samcot 8 (11.90 ± 1.27 g). Samcot 11 recorded the highest number of seeds per boll (30.68 ± 1.50 g) while the least was recorded in Samcot 9 (26.82 ± 2.49). Samcot 8 has the highest weight of lint per plant (13.66 ± 1.10 g) while the least was recorded in Samcot 13 (6.34 ± 0.89 g). The distinct features of some genotypes in plant height, number of sympodial branches, boll size and weight of lint compared to other genotypes is a good indication of existence of high genetic variability and genotypes with desired characteristicscould be selectedand incorporated into cotton improvement programmes.

    Yield Attributes and Biochemical Compositions of Elites and Landraces of Pigeon Pea [Cajanus cajan (L.) Millsp]
    (NCRI Press, 2023-12-30) Daudu O.A.Y.; Falusi O.A.; Abubakar A.; Gado A.A.; Dangana M.C.; Audu M.A.I; Adebimpe Y.A.
    Cajanus cajan (L.) Millsp (Pigeon pea) is an important leguminous crop grown mostly in the tropical regions of the world, Nigeria inclusive. The crop is still underutilised in Nigeria; the potentials of the crop in terms of yield traits and biochemical compositions, with ability of enhancing food security and preventing over-dependent on very expensive animal protein, is yet to be fully exploited. It was based on this premise that this study was designed. Twenty-five (25) accessions were obtained from International Institute of Tropical Agriculture, lbadan; National Centre for Genetic Resources and Biotechnology, Ibadan and Local farmers in Oyo state, Nigeria. The accessions were sown in the experimental farm in a Randomised Complete Block Design (RCBD) with three replicates. Standard procedures were followed for determination of yield parameters as well as biochemical compositions. It showed that NG/SA/11/08/108 produced the highest number of pods per plot (437.00) and the highest grain yield (2.6t/ha). Similarly, TCC-8126 produced the highest crude protein (22.53 %) while PG/OY/18/002 had the highest carbohydrate contents (52.22 %). TCC-8126 was the best elite genotype in terms of amino acid profile, containing glutamic acid (18.10 %), aspartic acid (11.4 %); arginine (7.41 %), alanine (5.90 %). The values produced for both nutritional compositions and amino acid profiles were within the recommended standard limits set by Food and Agriculture Organisation and United States Department of Agriculture. NG/SA/11/08/108, NG/AO/MAY/09/021/02, TCC-151, TCC-8126, TT-8129 and TCC-2 have been selected as promising genotypes that could serve as breeding lines for future breeding programme of Cajanus cajan in Nigeria.
