Gelatinization temperature (GT) and gel consistency (GC) are of important traits in determination of rice quality. In present work four rice cultivars namely Sang-e-Tarrom, Gerdeh, IR229 and IRRI2 have been utilized in hybridization as parents. In order to know about genetic characteristics and inheritance of the related traits, direct and reciprocal crosses have been conducted between parents Sang-e-Tarrom and Gerdeh, and between IR229 and IRRI2. Inheritance of related traits have been studied in direct and reciprocal hybridizations for hard, intermediate and soft GC, low and high GT. For these evaluations P1, P2, F1, F2, BC1, BC2 generations and their reciprocal crosses have been utilized in present work. Results showed that gene hard GC dominates on intermediate and soft and also intermediate GT dominates on low. From direct and reciprocal crosses Gerdeh × Sang-e-Tarrom and IR229 × IRRI2 have been illustrated that GC and GT expressions are under monogenic control of one major gene corresponding with several modifier genes. Gene dosage effects play a tremendously important and effective role in segregation production among traits. Regarding to the obtained results selections can effectively be performed in later segregation generations for GC and in early generations for GT.

Cumin, a member of the Umbelifereae family, is one of the oldest and economically most important spices. Generally, there is limited information about in vitro culture of Cuminum cyminum. A simple method was developed for regeneration of Cumin. This method yielded a large number of shoots within short period of time (30–40 days) without any sub culturing. The effect of different media and various combinations of plant growth regulators (PGRs) on callus formation and shoot regeneration were investigated. Simultaneous callus and shoot regeneration were obtained. The experiment was conducted in a completely randomized design with 30 treatments and 5 replications per treatment. The best response for shoot regeneration was observed on B5 medium containing 0.1 mg l−1 α-Naphthalene acetic acid (NAA) and 4 mg l−1 Kinetin (Kin). The B5 medium containing 2 mg l−1 NAA and 2 mg l−1 Kin was the best treatment for callus and root induction and regeneration simultaneously.
孜然，伞形科的一员，是最古老和经济上最重要的香料之一。一般来说，关于小茴香离体培养的资料有限。建立了一种简便的小茴香再生方法。该方法可在短时间内(30-40天)获得大量芽，无需继代培养。研究了不同培养基及不同植物生长调节剂组合对愈伤组织形成和芽部再生的影响。同时获得愈伤组织和芽再生。试验采用完全随机设计，30个处理，每个处理5个重复。在含有0.1 mg l−1 α-萘乙酸(NAA)和4 mg l−1 Kinetin (Kin)的B5培养基上，再生效果最好。含2mg l - 1 NAA和2mg l - 1 Kin的B5培养基对愈伤组织和根的诱导和再生效果最好。
