Abstract. Purnamasari I, Sobir, Syukur M. 2019. Diversity and inheritance in cowpea (Vigna unguiculata) on protein and yield components characters. Biodiversitas 20: 1294-1298.  Diallel was a method that can be used to see inheritance and diversity character of plants. The objective of this study has evaluated the inheritance and diversity of the yield component characters and seed protein content. This study used genetic material from five homozygous cowpeas (Vigna unguiculata (L.) Walp) genotypes (KM1, KM2, KM4, KM5, and TG2) and 20 F1. Genotypes were planted using a randomized complete block design with three replications. The character observed were the yield components (weight of 100 seed, number of seeds per pod, number of pods per bunch, number of pods per plant and yield) and seeds protein content. Characters that were influenced by general combining ability (GCA) consist of weight of 100 seeds, number of pods per bunch, number of seeds per pod and seed protein content. The variance of GCA has a greater value than the variance of specific combining ability (SCA). Narrow sense and broad sense heritability values were high category consist of weight 100 seed, number seeds per pod, number pods per bunch and seed protein content. That characters were inherited additively. Characters were influenced by additive gene action and have high diversity make it possible to select in F2 generation using the pedigree selection method.

ABSTRACT: Brown chickpea (Cicer arietinum L.) is one of the two chickpea types grown in Pakistan and other countries. The critical period for weed removal in a rainfed chickpea system is an important consideration in devising weed management strategies. Field experiments were conducted in the winter season of 2011 and 2012 to determine the extent of yield loss with different periods of weed crop competition. Seven weed crop competition periods (0, 45, 60, 75, 90, 105 and 160 days after sowing - DAS) were used to identify the critical period for weed removal in rainfed chickpea. Experimental plots were naturally infested with Euphorbia dracunculoides and Astragalus sp. in both years. Individual, composite density and dry weights of E. dracunculoides and Astragalussp. increased significantly with an increase in the competition period. However, yield and yield-contributing traits of chickpea significantly decreased with an increase in the competition period. Chickpea seed yield loss was 11-53% in different weed crop competition periods. Euphorbia dracunculoides and Astragalus sp. removed 39.9 and 36.9 kg ha-1 of N, 9.61 and 7.27 kg ha-1 of P and 38.3 and 36.9 kg ha-1 of K, respectively. Season long weed competition (160 days after sowing) resulted in 19.5% seed protein content compared with 24.5% seed protein content in weed-free chickpea. A Logistic equation was fitted to yield data in response to increasing periods of weed crop competition. The critical timing of weed removal at 5 and 10% acceptable yield losses were 26 and 39 DAS, respectively. The observed critical period suggests that in rainfed chickpea, a carefully timed weed removal could prevent grain yield losses.

The Impact

Soybean variety Bunya was developed in Australia to provide a better quality bean for tofu manufacturers. It is null for globulin subunit 11SA4. We investigated the effect of both the Bunya genetic background and the11SA4 subunit on tofu properties using genotypes containing 11SA4, with and without Bunya parentage, or lacking 11SA4 with Bunya parentage. Both Bunya parentage and 11SA4 significantly influenced globulin subunit composition and tofu texture. The group lacking 11SA4 had lower seed protein content, the largest seeds and the highest 7S and the lowest 11S content and produced the hardest tofu. Examination of the impact of 11SA4 null on tofu texture at four protein contents (380–440 g kg–1) over four coagulant (2.0–3.5 g kg–1) levels revealed that the absence of 11SA4 produced firmer tofu across the protein and coagulation levels tested, and this difference was larger than that from higher protein or coagulation levels. These results demonstrated that the absence of the 11SA4 subunit could increase tofu hardness to a level that otherwise could only be achieved with much higher seed protein content.
