An increasing trend of soybean production and consumption has been seen in the Philippines. To assess the potential of the soybean germplasm for utilization, diversity of the Philippine soybean collection was established. High diversity was marked on 17 out of 29 qualitative characters, which include plant growth habit, leaf blistering and flower standard color. Phenotypic diversity indices (H&rsquo;) of 92 soybean accessions averaged at 0.62. This aside, traits identical to a variety of soybean with superior characters were all present in the soybean germplasm collection. Using simple matching similarity coefficient, cluster analysis separated the different accessions into 12 distinct clusters at 62% similarity. Categorical Principal Component Analysis (CATPCA) showed that two independent components accounted for 35.36% of the total variation of the qualitative morphological characters. Factor loadings for each component showed the morphological characters, such as pubescence color, flower wing color, and seed coat color, that were contributing to the high projections in the two principal components. Accessions with vigorous seedlings were also observed. With the marked trait diversity, the soybean collection could be potentially used directly and for breeding purposes. Consequently, to uncover further the potential of our genetic resources at hand, the remaining germplasm accessions at NPGRL should be characterized and evaluated.

Phenotypic diversity of soybean (Glycine max (L.) Merr.)&nbsp;accessions in the Philippines for utilization

Background: This study refers to selecting the influence of various EGRs (explant growth regulators) and their specific concentrations at in vitro micropropagation efficiency (including shoot propagation and rooting) of potato and subsequently, to evaluate the resulting micro propagated plantlets capacity to tolerate drought stress under controlled conditions. 
&nbsp; 
Methods: The study was directed to determine the optimal concentrations of BA (benzyl adenine) with (0, 0.5, 1 and 1.5 mg/L), GA3 (gibberellic acid) with (0, 0.1, 0.2 and 0.3 mg/L) and Kin (kinetin) with BA (0, 0.5, 1 and 1.5 mg/L) to stimulate micro tuber formation in the potato varieties Borin and Naima and induction drought was PEG with (0, 0.5, 1 and 1.5 g/L) used. The work was carried out by complete randomized design (CRD) where the number of samples by which the analysis was performed was 112 unit experimental that resulted from the use of two varieties of potato and three replications. 
&nbsp; 
Result: The results revealed that BA at 0.5 mg/L exhibited best shoot growth number reached 10.8 shoot/explant in Naima. BA in 0.5 mg/L and Kin of 1 mg/L resulted in the best number and dimeter of micro tuber reached to 18.5 tuber/explant in Naima.
